In this study the effect of responses of Catharanthus roseus to NaCl stress has been explored. Periwinkle plants were exposed to different concentrations of salt and the effect of treatment on germination, growth parameter and antioxidative defense system investigated. Seeds were presoaked in solutions with different salinity after sterilization. Experimental samples irrigated once every two da...

as sesame is a somewhat neglected crop, information concerning its response to salinity is lacking. the effects of nacl stress were studied on seven genotypes of sesamum indicum l. the 6-weeks-old sesame seedlings were treated with different nacl concentrations (0, 30, and 60 mm). the nacl caused significant decreases in fresh and dry mass of all genotypes; however responses of genotypes to the...

The present investigations were undertaken to ascertain the extent of lipid peroxidation, oxidative stress and antioxidative system during ripening of two varieties of ber fruits (Ziziphus mauritiana Lam.) differing in their shelf lives, viz. Umran (8–9 days) and Kaithali (4–5 days). Based on visual observations, fruits were categorized as immature green (IG), mature green (MG), turning colour ...

Nitrogen (N) deficiency affects plant growth and crop yield. In this study, we investigated the role of glucose-6-phosphate dehydrogenase (G6PDH) in response to N availability three soybean cultivars, JINDOU 19 (JD19), LONGHUANG 3 (LH3), LONGDOU 2 (LD2), that have different tolerances low-N stress. The results showed leaf area primary root length JD19 LH3 were greater than LD2 under stress, sug...

lentil is considered as salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. this pot experiment was conducted to determine the effect of exogenous salicylic acid (sa) application on physiology, growth, yield and yield components of lentil grown under salt stress in greenhouse conditions, in a factorial arrangement based on randomized...

Salinity is one of the most important abiotic stresses that limit crop growth and productivity. This study focuses on the effects of different strains of plant growth promoting rhizobacteria (PGPR) on the physiological responses of two wheat cultivars under normal and salt stress conditions. The wheat cultivars selected include one which is tolerant to salinity (Kavir) and one which is sensitiv...

The properties of nanomaterials and their potential applications have been given considerable attention by researchers in various fields, especially agricultural biotechnology. However, not much has been done to evaluate the role or effect of zinc oxide nanoparticles (ZnO-NPs) in regulating physiological and biochemical processes in response to saltinduced stress. For this purpose, some callus ...

Salinity affects normal growth and development of plants depending on their capacity to overcome the induced stress. The present study was focused on the response and regulation of the antioxidant defence system in Brassica oleracea roots under short and long salt treatments. The function and the implications of hydrogen peroxide as a stressor or as a signalling molecule were also studied. Two ...

The effects of double stress environment i.e. lead (heavy metal) and NaCl (saline) on the activity of antioxidant enzymes in Vigna radiata seedling were studied. The antioxidant activities of enzymes, i.e of superoxide dismutase, catalase, ascorbate peroxidase, guaiacol peroxidase, glutathione reductase and their activity proportions were examined. Superoxide dismutase, ascorbate peroxidase, gu...
