Hormones-induced modifications in the response of wheat flag leaf to NaCl

Original Papers


A field experiment was carried out to investigate the effects of presoaking the wheat grains (Triticum aestivum L.) in 33 or 66 mM NaCl and indolyl-3-acetic acid (IAA at 50 g m−3), gibberellic acid (GA3 at 100 g m−3) or kinetin (100 g m−3) on some tolerance criteria in wheat flag leaf at different stages of development. At various stages of flag leaf development pretreatment with 33 or 66 mM NaCl decreased degree of succulence (particularly 66 mM), relative growth rate, net assimilation rate, relative water content, K+ content and K+/Na+ ratio and at the same time induced accumulation of abscisic acid and Na+. In the majority of cases grain pretreatment with GA3 or kinetin and to a lesser extent with IAA alleviated either partially or completely the deleterious effect of salinity on the above mentioned parameters.
