Two field experiments were conducted during the two winter seasons of 2002/2003 and 2003/2004 in a private farm with reclaimed sandy soil at El-Nagah village, South El-Tahrir provience El-Behaira Governorate Egypt. The experiments aimed to study the effect of foliar treatme>nts with different concentrations of α-tocopherol, (100, 200 and 400 mg L<sup>-1</SUP>) ascorbic acid (100, 200 and 400 mg L<sup>-1</SUP>) or nicotinamide (25, 50 and 100 mg L<sup>-1</SUP>) on faba bean plants. The results indicated that, foliar spray with all treatments of antioxidants on faba bean plants induced increments regarding number of branches, leaves and leaves area/plant, fresh and dry weights of shoots as well as chlorophyll a, chlorophyll b and carotenoid contents as compared with the untreated plants after 75 days from sowing. Foliar application of antioxidants significantly increased plant height, number of branches, pods and seeds/plant; seed yield (g)/plant, 100 seed weight as well as seed and straw yield (ton/fed). Also total carbohydrate, crude protein, K, P and Ca contents in dry seeds were significantly increased. On the other hand, the results showed that, the different treatments in general induced marked reductions in vicine and convicine (the causative agents of favism) in yielded seeds. This reduction reached nearly to 42% as compared with those of the untreated plants. All the treatments of antioxidants induced significant decrease in lipid peroxidation and oxidative enzymes such as polyphenol oxidase, peroxidase, catalase and superoxide dismutase activities in faba bean shoots compared with the control values. The maximum yields of seed and straw (ton/fed) of faba bean were obtained in response to 50 mg L<sup>-1</SUP> of nicotinamide or 200 mg L<sup>-1</SUP>> of α-tocopherol. In addition, the plants treated with 200 mg L<sup>-1</SUP> ascorbic acid, 50 mg L<sup>-1</SUP> nicotinamide and 400 mg L<sup>-1</SUP> ascorbic acid respectively recorded marked reduction in <I>vicine </I>and <I>convicine </I>contents. |
