Antagonistic bacteria of composted agro-industrial residues exhibit antibiosis against soil-borne fungal plant pathogens and protection of tomato plants from Fusarium oxysporum f.sp radicis-lycopersici
(2010)Rhizospheric and root-associated/endophytic (RAE) bacteria were isolated from tomato plants grown in three suppressive compost-based plant growth media derived from the olive mill, winery and Agaricus bisporus production ... -
Antifungal Activity of Plant Essential Oils Against Botrytis cinerea, Penicillium italicum and Penicillium digitatum
(2013)Plant essential oils have the potential to replace the synthetic fungicides in the management of postharvest diseases of fruit and vegetables. The aim of this study was to access the in vitro and in vivo activity of essential ... -
Aphid transmission of potato aucuba mosaic virus strains mediated by different strains of potato virus Y
(2000)Three British strains of potato aucuba mosaic virus (PAMV) were tested for transmissibility by the aphid Myzus persicae. None was aphid transmissible on its own but all three were transmitted in the nonpersistent manner ... -
The Aphidiinae (Hymenoptera : Ichneumonoidea : Braconidae) of Greece
(2001)Keys for the identification of genera and species of the subfamily Aphidiinae which occur in Greece as well as the observed parasitoid - aphid relations on various host plants are presented. -
Boron behavior in apple plants in acidic and limed soil
(2013)In dry Mediterranean-type climates boron (B) levels may naturally be high and even toxic to plants. Although liming of an acidic soil is expected to decrease B levels, it is not known what the effects would be in such areas ... -
Breeding Objectives and Selection Criteria for Milk Thistle Silybum marianum (L.) Gaertn. Improvement
(2013)Milk thistle [Silybum marianum (L.) Gaertn.] is an important medicinal-industrial plant. The medicinal compounds of milk thistle are derived from its seeds. The plant is commercially cultivated for the production of ... -
Catalytic Inhibition of Eukaryotic Topoisomerases I and II by Flavonol Glycosides Extracted from Vicia faba and Lotus edulis
(2011)Topoisomerases are essential enzymes involved in all processes of DNA metabolism, and their inhibitors have been identified as potential anticancer agents. The present study examined the effect of nine polyphenolic compounds ... -
Chronic stress and disease resistance in the genome model marine seaweed Ectocarpus siliculosus
(2013)In order to test the capacity of the genome model seaweed Ectocarpus siliculosus to acquire disease resistance, plantlets were repeatedly treated with the polyunsaturated fatty acids (PUFAs) linolenic and arachidonic acid ... -
Comparative efficiency of honeycomb and conventional pedigree methods of selection for yield and fiber quality in cotton (Gossypium spp.)
(2001)The effectiveness of honeycomb pedigree selection (HPS) as compared to conventional pedigree selection (CPS) was studied in one intraspecific (G. hirsutum L. x G. hirsutum L.) cross population (population I) and one ... -
Copper Availability in an Acidic and Limed Zeolite-Amended Soil
(2014)In acidic soils, copper (Cu) availability may be high because of Cu impurities of various agricultural additives. This research was aimed at assessing liming and zeolite application as availability reduction methods. In a ... -
Corn tolerance to atrazine and cadmium and sunflower to cadmium in soil and hydroponic culture
(2008)Hydroponic culture is often used for screening plant tolerance or remediation efficacy to environmental pollutants. Field experiments are usually avoided because of soil and groundwater contamination; thus pot experiments ... -
Correlation between plant growth regulator release rate and bioactivity for the series of newly synthesized phytoactive polymers
(2006)Phytoactive polymers are high molecular weight systems in which a plant growth regulator (PGR) unit is attached to the polymeric chain by a hydrolyzable chemical bond. The release rate of the PGR is linked to the biological ... -
Detection and characterization of fungicide resistant phenotypes of Botrytis cinerea in lettuce crops in Greece
(2013)The development of resistance to chemical control agents needs continuous monitoring in Botrytis cinerea. 790 isolates from lettuce and other vegetable crops were collected from six widely separated sites in Greece and ... -
Determinants of Woody Plant Species Richness in Abandoned Olive Grove Ecosystems and Maquis of Central Greece
(2015)The present study aimed to compare the woody plant species richness and cover (%) of five abandoned olive groves and five maquis ecosystems in central Greece and to describe the relationship between woody plant species ... -
Development of a Simplified Model for Nitrogen Fertilizer Recommendation for Maize, Wheat, and Sunflower in Northern Greece
(2013)In many cases, fertilizer crop recommendations in northern Greece are made based on personal opinions rather than scientific background. This may lead to overfertilization and waste of resources. For sound fertilizer ... -
Development, growth, feeding and reproduction of Ceratomegilla undecimnotata, Hippodamia variegata and Coccinella septempunctata fed on the tobacco aphid, Myzus persicae nicotianae
(2015)The demographic parameters and the larval aphid consumption of the predatory coccinellids Hippodamia variegata (Goeze) and Ceratomegilla undecimnotata (Schneider) were examined at five constant temperatures (17, 20, 23, ... -
Distribution and migration of insects and mites in flat storage containing wheat
(2001)Studies were conducted in a flat storeroom in central Greece, filled with approx., 90 tons of wheat, in order to evaluate insect and mite species abundance, and changes in population density and distribution among sampling ... -
Effect of Tillage System and Rimsulfuron Application on Weed Flora, Arbuscular Mycorrhizal (AM) Root Colonization and Yield of Maize (Zea mays L.)
