Abstract:

Water stress is one of the most important environmental factors that reduce growth; development and production of plants thus, the effects of water deficit stress and foliar application of ascorbic acid were studied on chlorophyll a and b, flavonoids, anthocyanin content and soluble sugar composition (glucose, xylose and mannose) in leaves of sunflower. A factorial pot experiment based on completely randomized design was used with three replications. Stress levels were consist, -0.03 (control), -0.6 and -1.2 MPa as first factor and ascorbic acid concentrations namely 0, 50, 100 and 150 mM were allocated to second factor. The results showed that, water deficit stress decreased chlorophyll content while increased flavonoids, anthocyanin and soluble sugars content. Ascorbic acid foliar application had significant effect on decrease of flavonoids, anthocyanin and soluble sugars content in stressed plants. All these results suggest that, ascorbic acid foliar application increases water stress resistance and we can use it on stressed plant in order to decrease adverse effect of water deficit stress.
