Abstract

STUDIES ON CHLOROPHYLL CHANGES IN HEALTHY AND DISEASED LEAF OF COWPEA (VIGNA UNGUICULATA (L.) WALP)

S. M. Talekar*

ABSTRACT

The present biochemical studies indicated that the chlorophyll content was found decrease due to the infection of Colletotrichum destructivum, Colletotrichum capsici and Erysiphe polygoni. In healthy leaves chlorophyll content was found to be more than infected leaves. In healthy leaf contained higher amount of chlorophyll a (0.692 mg/g), chlorophyll b (0.505 mg/g) and total chlorophyll (1.197 mg/g). The leaf infected with C. destructivum contained reduced amount of chlorophyll a (0.562 mg/g), chlorophyll b (0.367 mg/g) and total chlorophyll Colletotrichum destructivum was higher to the tune of 18.78, 27.32 and 27.73 %, respectively of chlorophyll a, chlorophyll b and total chlorophyll. Similar types of results made by Chavan (2013) on soybean. Similar kind of observation was made by (Berger et al. 2007, Lobato et al. 2009) on different host plant.
