Th e most of previous studies have been focused on the eff ect of water stress on plant yielding. However, the conditions in which plants grow from the moment of planting might aff ect their morphology and physiological response. Th e aim of this study was to examine the eff ect of water defi ciency on growth and plant physiological response of strawberry (Fragaria x ananassa Duch. cv. ‘Salut’)...

Ovipositional preference and larval survival of the diamondback moth, Plutella xylostella (L.), were compared among cabbage, Brassica oleracea L. variety capitata; glossy collards, Brassica oleracea L. variety acephala; and yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata in different treatments of planting density, host plant age, intercropping, and water stress in 2003 and 2004. P. x...

Plants are able to acclimate to new growth conditions on a relatively short time-scale. Recently, we showed that the progeny of plants exposed to various abiotic stresses exhibited changes in genome stability, methylation patterns and stress tolerance. Here, we performed a more detailed analysis of methylation patterns in the progeny of Arabidopsis thaliana (Arabidopsis) plants exposed to 25 an...

Contents of trans-zeatin riboside (ZR), dihydrozeatin riboside (DZR) and N6-(delta2-isopentenyl) adenosine (iPA) was quantified by an indirect ELISA using polyclonal antibodies, in the roots, xylem sap and leaves of pot grown sunflower plants subjected to water stress (RWC of leaves approximately 65 per cent). The delivery rates of all three cytokinins decreased significantly under stress. Cyto...

With frequent fluctuations in global climate, plants are exposed to co-occurring drought and pathogen infection and this combination adversely affects plant survival. In the past, some studies indicated that morpho-physiological responses of plants to the combined stress are different from the individual stressed plants. However, interaction of drought stressed plants with pathogen has not been...

Dimethylsulfoniopropionate (DMSP) and dimethyl sulphide (DMS) are compounds found mainly in marine phytoplankton and in some halophytic plants. DMS is a globally important biogenic volatile in regulating of global sulfur cycle and planetary albedo, whereas DMSP is involved in the maintenance of plant-environment homeostasis. Plants emit minute amounts of DMS compared to marine phytoplankton and...

Exposure to transient 10-days boron (B) deficiency stress created during different periods of growth cycle of nodulated soybean plants grown in a liquid culture was found to inhibit the nodule number and to increase the nodule dry weight. Nodule fresh weight was decreased in the stressed plants especially in the older ones. The loss of tissue water in the B-deficient nodules was accompanied by ...

The interactive effects of nickel (Ni) and ascorbic acid (AsA) and gibberellin (GA3) on soybean seedlings (Glycine max L. cv. Union × Elf) were examined. Seven-day old hydroponically-grown seedlings were exposed to NiCl2, 6H2O (0.5 mM), either with or without AsA (1 mM) or GA3 (0.05 mM) or AsA (1 mM) plus GA3 (0.05 mM), for five days. Nickel toxicity symptoms, such as formation of reddish-brown...

Plants of four soybean (Glycine max L. Merrill) genotypes differing in their ability to accumulate iron were studied. The efficient genotypes were Hawkeye (HA) and A62-9 (E-9), and the inefficient ones were PI-54619-5-1 (PI) and A62-10 (I-10). When plants of opposite efficiency were grown in the same solution, iron accumulation decreased in the primary leaves of efficient plants, but it was una...

Drought is a major limiting factor of crop productivity worldwide and its incidence is predicted to increase under climate change. Drought adaptation of cool-season grasses is thus a major challenge to secure the agricultural productivity under current and future climate conditions. Endophytes are non-pathogenic plant-associated bacteria that can play an important role in conferring resistance ...
