A pot experiment was performed at Helwan University Experimental Farm, Cairo, Egypt during the season of 2016-2017. This experiment aimed to study the response of vegetative growth criterea, seed yield (weight) and some metabolic activities and constituents of cowpea (Vigna unguiculata L.) plants to foliar spray of ascorbic acid (AA; 100, 150 and 200 ppm) and gallic acid (GA; 100, 150 and 200 ppm), two antioxidant compounds. The foliar application of AA and GA significantly increased all growth criteria (i.e. length of roots and stem, the root and stem fresh and dry weights, No. of leaves and total leaves area cm2/plant), as well as seed weight and quality compared to the untreated control plants. Total photosynthetic pigments (TPP), total carbohydrate (TC),... view more»
