Timing of salicylic acid application affects the response of maize ( L.) hybrids to salinity stress.

The effect of genotype and timing of salicylic acid (SA) application on response of maize to salinity stress has been investigated. Single and triple hybrids (SH and TH, respectively) of maize were grown hydroponically and sprayed with 1 mM SA one week either before or after application of 150 mM NaCl. The effect of salinity on maize performance was stronger than that of SA regime or maize hybrid.

Roles of dehydrin genes in wheat tolerance to drought stress.

Physiological parameters and expression levels of drought related genes were analyzed in early vegetative stage of two bread wheat cultivars (Sids and Gmiza) differ in drought tolerance capacity. Both cultivars were imposed to gradual water depletion started on day 17 till day 32 after sowing. Sids, the more tolerant cultivar to drought showed higher fresh and dry weights than the drought sensitive genotype, Gmiza.
