Abstract
This experiment was conducted to evaluate the impact of foliar application of glycinebetaine on vegetative and reproductive growth stages of two wheat (Triticum aestivum L.) varieties under Na 2 SO 4 stress (150mM). There were three levels (0mM, 50mM and 100mM) of glycinebetaine (GB) applied as foliar spray. Data regarding biomass, growth parameters, gaseous exchange and antioxidant activities were recorded. Salt stress reduced the growth attributes, Net CO 2 assimilation rate and antioxidant activities. However, foliar spray of GB reduced the toxic effects of salinity. GB improved the photosynthetic rate of Na 2 SO 4 -treated plants of both varieties; it also increased the activities of antioxidant enzymes, such as CAT and POD under saline environment. Both levels of GB i.e. 50 mM and 100 mM were almost equally effective in affecting the POD activity in salt treated plants. Finally it can be concluded that salinity tolerance can be induced by foliar application of GB.
