  In a three-year (2004-2006), field experiment, we aimed to study changes in leaf physiological traits (leaf water potential-Ψleaf, leaf water content-LWC, carbon isotope discrimination-Δ, specific leaf area-SLA, chlorophyll content as assessed by SPAD and modified SPAD-MSPAD) and elemental composition (K, Na, Ca, Mg, K/Na, Ca/Mg, total leaf salinity-TLS) of sugar beets (cv. Rizor) grown unde...

 In order to investigate the effect of salicylic acid and humic acid to mitigate the impact of drought tension during pollination of forage maize, the present experiment was conducted as split plots based on randomized complete blocks design with three replications at Isfahan University of Technology. Drought tension levels included: without tension (control), mild tension (75 percent crop capa...

The effects of irrigation, dry farming and drought treatments on the activities of antioxidant enzymes including superoxide dismutase, ascorbate peroxidase, catalase and peroxidase in barley leaves at different generative growth stages under field conditions were investigated. Three senescence parameters including chlorophyll, total soluble protein and rubisco large subunit protein loss, were a...

The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...
