Effect of Exogenous Applications of Glycine Betaine on Chlorophyll and Biochemical Attributes of Two Maize (Zea mays L.) Cultivars under Saline Conditions

This experiment was conducted to observe that whether the glycine betaine exogenous application induce the salt tolerance in maize cultivars or not. Experiment was laid dwon in CRD at University of Gujrat, Gujrat-Paksitan during 2011. On the basis of results of the present studies it can be concluded that Salt stress greatly affect chlorophyll a,b, Carotenoids and biochemical parameters of both maize cultivars but exogenous application of glycinebetaine ameliorates the harmful effects of salt stress. However the 100mM GB spray was more affective than 50mM GB application. As whole the glycine betaine induced the salt tolerance in both cultivars in relation chlorophyll and biochemical attributes of maize under saline conditions.
