Harold C. Passam, Ioannis C. Karapanos, Penelope J. Bebeli, Dimitrios Savvas (Greece) A Review <strong>of</strong> Recent Research<br />

on Tomato Nutrition, Breeding <strong>and</strong> Post-Harvest Technology with Reference to Fruit Quality (pp 1-21)<br />

ABSTRACT<br />

Special Feature: <strong>The</strong> continued importance <strong>of</strong> tomato (Lycopersicon esculentum Mill.) as a vegetable <strong>and</strong> salad commodity is<br />

reflected by the large volume <strong>of</strong> research on virtually all aspects <strong>of</strong> the crop. Since 2000, over a thous<strong>and</strong> scientific papers per<br />

year relating to tomato research have been published, not including those in the less widely read literature, conference <strong>and</strong><br />

workshop proceedings. In the present paper, we survey recent findings in the areas <strong>of</strong> tomato nutrition, the influence <strong>of</strong> salinity<br />

on nutrition <strong>and</strong> growth, tomato breeding <strong>and</strong> genetic resources, <strong>and</strong> the post-harvest physiology, storage <strong>and</strong> ripening <strong>of</strong> fruit.<br />

Research findings are considered particularly with respect to fruit quality, as reflected in the quality st<strong>and</strong>ards <strong>of</strong> the <strong>European</strong><br />

Union.<br />

Fabio Stagnari (Italy) A Review <strong>of</strong> the Factors Influencing the Absorption <strong>and</strong> Efficacy <strong>of</strong> Lipophilic <strong>and</strong> Highly Water-Soluble<br />

Post-Emergence Herbicides (pp 22-35)<br />

ABSTRACT<br />

Invited Review: It is well known that post-emergence herbicide uptake into plant foliage <strong>and</strong> efficacy varies with plant <strong>and</strong><br />

chemicals, <strong>and</strong> can be greatly influenced by adjuvants <strong>and</strong> environmental conditions. <strong>The</strong> penetration <strong>of</strong> herbicides into plant<br />

leaves is related to the physicochemical properties <strong>of</strong> the active ingredients, especially molecular size <strong>and</strong> lipophilicity. For a<br />

specific herbicide, uptake varies greatly with plant species <strong>and</strong> there is no simple method at the moment to quickly evaluate the<br />

leaf surface permeability <strong>of</strong> a plant. Furthermore, current evidence suggests that highly-water soluble, ionic herbicides may be<br />

more sensitive to some environmental conditions (low humidity <strong>and</strong> rapid drop drying) than lipophilic herbicides. Various<br />

adjuvants are being used to increase the penetration <strong>of</strong> herbicides into target plant foliage, but their effect varies with chemicals<br />

<strong>and</strong> plant species. <strong>The</strong> mechanisms <strong>of</strong> action <strong>of</strong> adjuvants in enhancing herbicide uptake remain unclear despite the effort<br />

made during the last three decades. A better underst<strong>and</strong>ing <strong>of</strong> the transcuticular transport <strong>of</strong> herbicides <strong>and</strong> the mode <strong>of</strong> action<br />

<strong>of</strong> adjuvants should lead to a more rational use <strong>of</strong> herbicides <strong>and</strong> minimize their negative impact on the environment.<br />

Rosario Nicoletti, Francesco Raimo, Gaetano Miccio (Italy) Diplotaxis tenuifolia: Biology, Production <strong>and</strong> Properties (pp<br />

36-43)<br />

ABSTRACT<br />

Invited Mini-Review: Perennial wallrocket (Diplotaxis tenuifolia (L.) DC) is a perennial herbaceous plant belonging to the<br />

Brassicaceae native <strong>of</strong> the Mediterranean area <strong>and</strong> western Asia, but has now become cosmopolitan. Once harvested as a<br />

spontaneous herb, today it is a crop species whose importance is increasing especially in Europe after the diffusion <strong>of</strong><br />

ready-to-use salads. Leaves present interesting nutritional properties depending on their content in glucosinolates <strong>and</strong> some<br />

antioxidant compounds, such as vitamin C <strong>and</strong> flavonoids, <strong>and</strong> their consumption is recommended in the prevention <strong>of</strong> cancer<br />

<strong>and</strong> cardiovascular diseases. Italy is the main producer country in the world with over 1100 hectares cropped in 2003. However,<br />

production in home gardens <strong>and</strong> harvesting from the wild are still quite significant, which makes figures concerning the overall<br />

production underestimated. It is cultivated both in open fields <strong>and</strong> under plastic tunnels, mostly in rotation with other vegetable<br />

crops in areas <strong>of</strong> intensive horticulture. Besides its relevance as a food crop, it is also thought to possess therapeutic properties<br />

that have stimulated its use in the traditional medicine <strong>of</strong> several peoples in the Mediterranean <strong>and</strong> the Near East areas. An oil<br />

rich in erucic acid can be extracted by the seeds, introducing possible relevance for industrial applications. Aspects concerning<br />

biology, diffusion, cultivation, crop protection, industrial processing, nutritional properties <strong>and</strong> uses <strong>of</strong> perennial wallrocket are<br />

considered in this review.


Daniele Prodorutti, Ilaria Pertot, Lara Giongo, Cesare Gessler (Italy) Highbush Blueberry: Cultivation, Protection, Breeding<br />

<strong>and</strong> <strong>Biotechnology</strong> (pp 44-56)<br />

ABSTRACT<br />

Invited Review: Highbush blueberry is one <strong>of</strong> the most commercially significant berry crops. It is mainly cultivated in the United<br />

States <strong>and</strong> Canada, but also in Europe, Australia, Chile <strong>and</strong> New Zeal<strong>and</strong>. Production <strong>of</strong> this crop is likely to increase in<br />

response to increased consumer dem<strong>and</strong> for healthy foods, including the antioxidant-rich blueberry. This review describes<br />

several issues <strong>and</strong> developments in sustainable blueberry farming, including agronomical <strong>and</strong> cultural techniques (mulching,<br />

irrigation, the beneficial effects <strong>of</strong> mycorrhizae <strong>and</strong> fertilization), disease management (biology <strong>and</strong> control <strong>of</strong> common <strong>and</strong><br />

emerging diseases), pest management, pollinators (effects on fruit set <strong>and</strong> production), conventional breeding <strong>and</strong> molecular<br />

techniques for examining <strong>and</strong> engineering blueberry germplasm. This paper describes past problems <strong>and</strong> current challenges<br />

associated with the commercial production <strong>of</strong> highbush blueberry, as well as new approaches <strong>and</strong> techniques for improving<br />

crop quality <strong>and</strong> future perspectives for innovative research.<br />

Yaşar Akça, A. Aytekin Polat (Turkey) Present Status <strong>and</strong> Future <strong>of</strong> Walnut Production in Turkey (pp 57-64)<br />

ABSTRACT<br />

Invited Review: Turkey is one <strong>of</strong> the most important producers <strong>of</strong> walnut in the world. In 2005, Turkey ranked fourth in world<br />

production with 133,000 t <strong>of</strong> production. According to the average 2000-2005 statistics, Turkish walnut production accounts for<br />

8.89% <strong>of</strong> the World’s total walnut production. This important role is due to Anatolia being a germplasm center, <strong>and</strong> to its suitable<br />

ecological conditions. Walnut has an exceptionally wide natural distribution in Turkey <strong>and</strong> it is a plant which does not need much<br />

labour <strong>and</strong> annual high operating costs. In general, walnut has been grown at the edge <strong>of</strong> farml<strong>and</strong>s in recent years in Turkey.<br />

Cultivated mainly for its nutritious nuts, it is used as a food, in the chocolate industry, for baked foods, <strong>and</strong> in the pharmaceutical<br />

<strong>and</strong> cosmetic industries. <strong>The</strong> leaves <strong>and</strong> green shells are used as a pigment in Turkey. Continuous seed propagation for<br />

thous<strong>and</strong>s <strong>of</strong> years in Turkey has given rise to a great number <strong>of</strong> seedling walnut trees, which represent valuable walnut gene<br />

resources. <strong>The</strong> number <strong>of</strong> native trees is estimated to be over 6 million <strong>and</strong> they possess large genetic variability in yield, nut<br />

<strong>and</strong> kernel characteristics, late bud breaking, late flowering, winter hardiness, tolerance to disease. After recognition <strong>of</strong> the<br />

importance <strong>of</strong> propagation by grafting <strong>and</strong> budding by growers in recent years, the orchards are being established by st<strong>and</strong>ard<br />

cultivars. <strong>The</strong>se st<strong>and</strong>ard walnut orchards are generally planted with cultivars selected in Turkey.<br />

Lena Ekelund, Fredrik Fernqvist (Sweden) Organic Apple Culture in Sweden (pp 65-75)<br />

ABSTRACT<br />

Invited Review: Sweden is a net importer <strong>of</strong> all fruit, including apples – the fruit favoured by Swedish consumers. Domestic<br />

apple production holds a market share <strong>of</strong> a fifth <strong>of</strong> the total supply, while the domestic market share <strong>of</strong> organic apples is only<br />

11%. <strong>The</strong> fact that organic imports are transported long distances may be in conflict with the environmental arguments. <strong>The</strong><br />

organic share <strong>of</strong> around 1% <strong>of</strong> total apple consumption is significantly lower than the 3% organic share <strong>of</strong> all food sales. <strong>The</strong><br />

price premium <strong>of</strong> organic apples is an additional two thirds <strong>of</strong> the conventional price. Organic apple culture constitutes <strong>of</strong> less<br />

than 10% <strong>of</strong> total Swedish apple acreage, while the area certified by the association KRAV is less than 5%. This label has been<br />

crucial in the marketing <strong>of</strong> organics but may now be replaced by EU certification. A few vertically integrated retail chains, with<br />

continuously fewer <strong>and</strong> bigger units, dominate the Swedish food marketing system, but organic apples are <strong>of</strong>ten sold directly to<br />

the consumers, as fresh or as processed products, which may give the producer a higher share <strong>of</strong> the price premium paid for<br />

organic products. Considering the br<strong>and</strong> strategies <strong>of</strong> the supermarkets, the key to market success may be to find a niche in the<br />

small-scale system, possible with ties to the tourist industry, since this <strong>of</strong>fers a channel for small volumes <strong>and</strong> a wide range <strong>of</strong><br />

unusual varieties. This combines the advantages <strong>of</strong> local products with those <strong>of</strong> organics.<br />

Kalomira Elena (Greece) Asparagus Diseases (pp 76-83)<br />

ABSTRACT<br />

Invited Review: Crown <strong>and</strong> root rot is the most serious disease <strong>of</strong> asparagus worldwide resulting in plant yellowing, dieback<br />

<strong>and</strong> wilting. As the disease progresses, root parenchyma is completely destroyed whereas crown interior is discolored. <strong>The</strong><br />

fungi that play major role to this disease are species <strong>of</strong> the genus Fusarium. <strong>The</strong> two dominant species are F. oxysporum f. sp.<br />

asparagi <strong>and</strong> F. proliferatum. <strong>The</strong> species F. solani, F. culmorum, F. subglutinans <strong>and</strong> Phytophthora spp. are less frequently


isolated from diseased asparagus plants. Besides, Fusarium species are the main biotic factors responsible for asparagus<br />

decline syndrome. Seeds, crowns, root residues <strong>and</strong> field soil consist the pathogen inoculum sources. Yield loss results from<br />

plant death <strong>and</strong> from smaller <strong>and</strong> fewer spears. Other economically important fungal diseases are asparagus rust, caused by<br />

Puccinia asparagi that infects asparagus green parts <strong>and</strong> the purple spot, caused by Stemphylium spp. which appears as brown<br />

lesions with dark purple margins on the main stems, branches <strong>and</strong> cladophylls. Both diseases cause a severe drop <strong>of</strong><br />

cladophylls while the plants turn yellow or brown; they also reduce the vitality <strong>of</strong> the root system resulting in the subsequent<br />

year yield reduction. Other fungal diseases <strong>of</strong> asparagus include stem blight caused by Phomopsis asparagi, <strong>and</strong> Cercospora<br />

blight caused by Cercospora asparagi causing subsequent yield loss, particularly in humid areas. Furthermore, several viruses<br />

have been found to infect asparagus causing latent infections.<br />

Antonia Ivascu, Adriana Stinga (Romania) Collecting, Preserving <strong>and</strong> Using Gene Sources from Germplasm Found in Peach<br />

(Prunus persica L. Batsch.) Breeding in Romania (pp 84-90)<br />

ABSTRACT<br />

Invited Mini-Review: <strong>The</strong> collection, preservation <strong>and</strong> use <strong>of</strong> peach genetic resources from the germplasm found in<br />

SCDP-Baneasa is focused on disease <strong>and</strong> pest resistance (especially to Taphrina deformans, Sphaerotheca pannosa var.<br />

persicae, Monilinia, Cytospora cincta, Myzus persicae, Cydia molesta, <strong>and</strong> Anarsia lineatella), fruit quality (especially taste <strong>and</strong><br />

flavour), seasonality (with a ripening calendar that exceeds 3-4 months), adaptability <strong>of</strong> cultivars <strong>and</strong> rootstocks to adverse<br />

environmental conditions <strong>and</strong> also on high yield potential. <strong>The</strong> use <strong>of</strong> different sources <strong>of</strong> genes, including germplasm from<br />

China, or other areas with a large biodiversity confers resistance to diseases <strong>of</strong> the new peach <strong>and</strong> nectarine varieties bred <strong>and</strong><br />

created in Romania. Open pollination, hybridizations <strong>and</strong> back-crosses have been used as breeding methods, <strong>and</strong> have been<br />

combined with screening <strong>of</strong> progenies in the juvenile stage in greenhouse to reduce selection cycles <strong>and</strong> evaluation time.<br />

Mateja Germ, Vekoslava Stibilj, Ivan Kreft (Slovenia) Metabolic Importance <strong>of</strong> Selenium for <strong>Plant</strong>s (pp 91-97)<br />

ABSTRACT<br />

Invited Mini-Review: Selenium (Se) is a trace element that is both an essential nutrient for humans <strong>and</strong> animals <strong>and</strong> an<br />

environmental toxicant; the boundary between the two roles is narrow <strong>and</strong> depends on its chemical form, concentration, <strong>and</strong><br />

other environmentally influenced variables. Se is important in the metabolism <strong>of</strong> cyanobacteria <strong>and</strong> some plants, being involved<br />

in their antioxidative processes. <strong>The</strong> essentiality <strong>of</strong> Se to higher plants, however, is still under debate. Although it is harmful for<br />

plants in high concentrations, it can exert beneficial effects at low concentrations. It can increase the tolerance <strong>of</strong> plants to<br />

UV-induced oxidative stress, delay senescence, <strong>and</strong> promote the growth <strong>of</strong> ageing seedlings. Recently it has been shown that<br />

Se is able to regulate the water status <strong>of</strong> plants under conditions <strong>of</strong> drought. It is widely distributed on the Earth’s surface <strong>and</strong><br />

available for plants in at least small traces. Cultivation <strong>of</strong> plants enriched with Se could be an effective way <strong>of</strong> producing Se-rich<br />

foodstuffs which can be beneficial to health. Se is also a major contaminant in the effluents from some oil refineries, power<br />

plants, <strong>and</strong> in mine drainage water. Se has become the primary element <strong>of</strong> concern in much environmental contamination<br />

because <strong>of</strong> its bioaccumulation in food webs. Bioaccumulation <strong>of</strong> Se is leading to toxic impact <strong>and</strong> changes in communities.<br />

However, it is possible to remove it from soils <strong>and</strong> Se-contaminated agricultural drainage water using plants in a<br />

phytoremediation process.<br />

Jolita Radušienė (Lithuania) Conservation <strong>and</strong> Evaluation <strong>of</strong> Selected Medicinal <strong>and</strong> Aromatic <strong>Plant</strong>s from Lithuania (pp<br />

98-106)<br />

ABSTRACT<br />

Invited Mini-Review: This review focuses on research <strong>of</strong> medicinal <strong>and</strong> aromatic plants in Lithuania <strong>and</strong> describes how the<br />

conservation <strong>of</strong> genetic resources <strong>of</strong> these plants is considered. Biological peculiarities <strong>of</strong> species <strong>and</strong> their sources <strong>of</strong> raw<br />

material determine the mode <strong>of</strong> conservation including in situ <strong>and</strong> ex situ methods. <strong>The</strong> data on evaluation <strong>of</strong> essential oils <strong>of</strong><br />

native species (Achillea millefolium, Acorus calamus, Origanum vulgare, Helichrysum arenarium, Hypericum perforatum,<br />

Thymus ssp., Tanacetum vulgare) <strong>of</strong> commercial value in herbal medicine are presented. <strong>The</strong> morphological, chemical <strong>and</strong><br />

ecological markers support the selection <strong>and</strong> taxonomical identification <strong>of</strong> intra-specific diversity <strong>and</strong> are essential for<br />

germplasm conservation <strong>and</strong> utilization. <strong>The</strong> exploitation <strong>of</strong> the chemical diversity <strong>of</strong> evaluated species may be a potential<br />

source <strong>of</strong> genetic variation to allow selecting the valuable material for breeding.


Antónia Šrobárová, Ľubomíra Kakalíková (Slovak Republic) Fungal Disease <strong>of</strong> Grapevines (pp 107-110)<br />

ABSTRACT<br />

Invited Mini-Review: Grapes have the longest history <strong>of</strong> all the cultivated fruits <strong>and</strong> are among the most widely grown. Cooler<br />

temperatures <strong>and</strong> high relative humidity <strong>and</strong>/or moisture favour the development <strong>of</strong> fungal diseases <strong>of</strong> grapes. <strong>The</strong>se diseases<br />

affect the leaves, shoots, stems <strong>and</strong> fruit. Fungal diseases can render fruit unusable <strong>and</strong> can very easily cause severe losses in<br />

yield. Grapevines are fairly adaptable plants, growing in a wide variety <strong>of</strong> soil types, from light s<strong>and</strong> to packed clay, <strong>and</strong><br />

flourishing around the globe in the temperate b<strong>and</strong>s between 20° <strong>and</strong> 50° latitude, north or south <strong>of</strong> the Equator. Black rot<br />

mould (Botrytis bunch rot – B. fuckeliana (de Bary) Whetzel) are the most common fungal diseases <strong>of</strong> grapevine. Recently,<br />

decline symptoms (Phaeomoniella chlamydospora (W. Gams, Crous, M. J. Wingf. & L. Mugnai) in young grapevines have<br />

increased in areas with new planted vineyards resulting in poor vineyard establishment. In this review we describe symptoms <strong>of</strong><br />

disease <strong>and</strong> their management, <strong>and</strong> the effect <strong>of</strong> climatic factors.<br />

(Serbia) Serbian Dried Fruit Research (pp 111-116)<br />

ABSTRACT<br />

Invited Mini-Review: Serbia has a very long tradition <strong>of</strong> plum drying, <strong>and</strong> it used to be a recognized prune exporter on both a<br />

<strong>European</strong> <strong>and</strong> global scale. Investigations in the field <strong>of</strong> fruit drying have not always been in accordance with production <strong>and</strong><br />

export <strong>of</strong> dried fruits, prunes in particular. In times <strong>of</strong> the largest production <strong>and</strong> export, no adequate attention was devoted to<br />

the development <strong>and</strong> advancement in the respective field, i.e. application <strong>of</strong> the results <strong>of</strong> the study, which accodingly resulted<br />

in a decrease in production <strong>and</strong> export in the ensuing period. Research aimed at advancing the technology <strong>and</strong> suitability <strong>of</strong><br />

particular cultivars for drying as well as quality <strong>of</strong> prune have been pursued ever since the 1960s. Convective drying is the most<br />

common method <strong>of</strong> fruit drying, especially plum drying, <strong>and</strong> is the major drying method in Serbia. <strong>The</strong> latest investigations<br />

include current research in the field <strong>of</strong> kinetics <strong>of</strong> convective drying, study <strong>of</strong> newly developed <strong>and</strong>/or combined methods <strong>of</strong> fruit<br />

drying (osmotic, vacuum, lyophilization, etc.) as well as procedures applicable to finishing <strong>of</strong> dried fruits.<br />

Wheat Cultivars after Inoculation with Three Isolates <strong>of</strong> Fusarium culmorum (W. G. Smith) Sacc. (pp 117-124)<br />

ABSTRACT<br />

Original Research Paper: During two vegetative periods – the end <strong>of</strong> September to the end <strong>of</strong> July – the grain <strong>of</strong> two wheat<br />

cultivars (‘Hana’ <strong>and</strong> ‘Samanta’) was inoculated with three isolates <strong>of</strong> F. culmorum (W. G. Smith) Sacc. Isolate I1 (KF 350) was<br />

the nivalenol (NIV)-producing chemotype while I2 (Haniska) <strong>and</strong> I3 (Vranov) were deoxynivalenol (DON)-producing<br />

chemotypes. In all experiments as well as in controls analysis <strong>of</strong> group B-trichothecenes (NIV, DON) <strong>and</strong> ergosterol (ERG)<br />

concentration was performed. Both wheat cultivars possessed resistance to invasion <strong>and</strong> to toxin accumulation <strong>and</strong><br />

degradation (mainly ‘Hana’). This component <strong>of</strong> resistance can be seen by kinetics curves where increased toxin production<br />

appears mainly after 14 <strong>and</strong> 21 days after inoculation. In spite <strong>of</strong> this, toxin production had a linear kinetics <strong>and</strong> small<br />

concentrations could be observed. However, a slight deviation from linearity was observed in 1998 at the 2 nd <strong>and</strong> 3 rd week <strong>of</strong><br />

vegetation while in 1999 at the 3 rd <strong>and</strong> 4 th week. <strong>The</strong> kinetics <strong>of</strong> ERG biosynthesis can be described as linear but the amount <strong>of</strong><br />

fungal biomass production depends on the environmental condition. F. culmorum isolates could be differentiated according to<br />

their chemotype; mycotoxigenicity was also confirmed. This is the first report <strong>of</strong> trichothecene contamination <strong>and</strong> their<br />

distribution during vegetation harvest in Slovakian wheat.
