Biochemical Effects of Phytotoxins on Chickpea and its Possible Role in Wilt Disease

Iftikhar A. Khan, S.S. Alam and A. Jabbar

Abstract:
Fusarium oxysporum f. sp. ciceris and its phytotoxins induced the leakage of electrolytes from chickpea leaflets, A direct correlation was found between the conductivity of the leaching solution and susceptibility to chickpea wilt. The resistant varieties (CM88 and ILC-3279) released lesser amount of electrolytes as compared to the susceptible varieties (Aug-424 and ILC-1929). The losses of most of the electrolytes such as phosphates, total phenols, protein, carbohydrates, K+ and Ca+ 2 were significantly higher in toxin treated tissues than in control of both the cultivars. There was a little effect of toxin on leakage of Na+ ion in resistant or in susceptible cultivars. The susceptible cultivars released higher amount of phosphates, carbohydrates and K+/Ca+2 ions from toxin treated tissues than the resistant cultivars.
