Physiological and metabolic changes of Cucurbita pepo leaves in response to zucchini yellow mosaic virus (ZYMV) infection and salicylic acid treatments
The changes of some physiological and biochemical parameters in pumpkin (_Cucurbita pepo_ cv Eskandarani) leaves associated with zucchini yellow mosaic virus (ZYMV) infection and the effect of exogenous application of salicylic acid (SA) were studied in this paper. In comparison to the untreated leaves, ZYMV infected leaves showed many symptoms, including severe mosaic, size reduction, stunting and deformation. Results from ... إقراء المزيد

Protective action of salicylic acid against bean yellow mosaic virus infection in Vicia faba leaves
In this study, morphological, ultrastructural and physiological modifications of faba bean (_Vicia faba_ cv Giza 461) leaves in response to bean yellow mosaic virus (BYMV) infection and salicylic acid (SA) treatments were examined. Under BYMV stress, leaves showed symptoms including severe mosaic, mottling, crinkling, size reduction and deformations. Three weeks after virus inoculation, photosynthetic rate, pigment contents and transpiration rate ... إقراء المزيد

Modifications of antioxidant activity and protein composition of bean leaf due to Bean yellow mosaic virus infection and salicylic acid treatments
The antioxidant status as well as protein composition of faba bean leaves infected with _Bean yellow mosaic virus_ (BYMV) and the effect of salicylic acid application was examined in this paper. Some modifications in the antioxidant status were observed by changing some antioxidant enzymes activities and contents of antioxidant metabolites. BYMV-infected leaves revealed POD, CAT, APX and SOD induced activities ... إقراء المزيد

Salicylic acid alleviates growth inhibition and oxidative stress caused by zucchini yellow mosaic virus infection in Cucurbita pepo leaves
The effects of zucchini yellow mosaic virus (ZYMV) infection and pretreatments with salicylic acid (SA) on biomass accumulation of pumpkin (_Cucurbita pepo_ cv. Eskandarani) were investigated. The response of photosynthesis, transpiration and the activities of antioxidant enzymes in leaves was also considered. Significant reductions in growth parameters (i.e. leaf area, biomass and shoot height), photosynthesis and chlorophyll _a_ and _b_ ... إقراء المزيد

Differential responses of esterase isoenzyme of peanut to salinity and drought as influenced by salicylic acid
* The effect of salinity, drought and salicylic acid on growth and esterase expression of peanut * plants were studied. Seeds of peanut were able to germinate even under relatively high * concentration of NaCl (157.5 mM) or PEG (25%). In general, seedling growth was less tolerant to * salt stress than vegetative growth stage of peanut plants grown in ... إقراء المزيد

Differential responses of esterase isoenzyme of peanut to salinity and drought as influenced by salicylic acid
The effect of salinity, drought and salicylic acid on growth and esterase expression of peanut plants were studied. Seeds of peanut were able to germinate even under relatively high concentration of NaCl (157.5 mM) or PEG (25%). In general, seedling growth was less tolerant to salt stress than vegetative growth stage of peanut plants grown in hydroponic culture containing NaCl, ... إقراء المزيد
