Abstract
Two field experiments were conducted at the experimental farm of Tag El




Ezz Agric. Res. station. Dakahlia during 2004/2005 and 200512006 seasons to study




the effect of three antioxidant substances (hydroquinone, citric acid and benzoic acid




at concentratåons of 5, lo and 15mM) on growth, yield and yield components of three




faba bean cultiva rs (Sakha 1, Giza 3 and Giza 2) as well as the severity of chocolate




spot disease caused by Botiytis fabae. Generally, the application of benzoic acid at




any concentration showed priority and proved to be the best and most effective ¡n




reducing disease severity on all tested cutivars. Hydroquinone came ¡n the second




order as compared to control treatment. Citric acid showed the lowest effect in this




respect.




The foliar application of antioxidants on (aba bean cultivars significantly




increased growth and yield components which could be summarized as follows: 1)




Sakha 1 cultivar surpassed Giza 3 and Giza 2 in number of branches, number of pods




and seed weight planf’, 100-seed weight and seed yield, but Giza 3 cultivar




surpassed Sakha 1 and Giza 2 in plant height and straw yield ¡n the two seasons, 2




Citric acid gave the highly significant increase ¡n number of pods & seed weight plnf




and seed yield in both seasons 3) Using 15mM of antioxidant substances ave higher




significant increase ¡n number of branches, pods and seed weight planf, 100-seed




weight and seed yield compared with control and 4) The interaction between (aba




bean cultivars and antioxidants had a significant effect on plant height in both seasons




and on the 100-seed weight and seed yield in the first and second seasons. Sakha 1




with citric acid was more effective ¡n this respect.
