Potential effects of growth regulator agents on antioxidant activity of two verities of faba bean (viciafabal.,)
Faba bean ( lessThan i greaterThan Vicia faba L lessThan /i greaterThan .) as the most cultivated leguminous species in the world, is an excellent source of protein, dietary fiber, micronutrients and phytochemicals. A field experiment was conducted at Ghazala, Zagazig University, Sharkia Governorate during 2015, to study the effect of plant Growth Regulator such as; Gibberellic acid (GA3) and Inidol acetic acid (IAA) on antioxidant contents of two genotype seed extracts Nubaria 1 and Miser 3. Both two varieties were treated with both GA3 and IAA at two levels 50 and 100 ppm and 100ppmGA3 +100ppm IAA as foliar treatments. The Nubaria 1 seeds extracts have highest contents of phenolics (13.51, 13.64, 16.94, 17.97 and 20.53 GAE/g and flavonoid (8.07, 8.06, 9.12, 10.28 and 11.86 mg/QE/g, respectively. Also genotype seed extracts (Nubaria 1) has have highest antioxidant capacity (82.82% DPPH). Plant growth regulators such as GA3 and IAA are improving biosynthesis of phenolics and flavonoids, therefore improve antioxidant capacity and nutrition value of seeds.
