Physio-Biochemical changes in lentil genotypes under biotic stress induced by Stemphylium botryosum Wallr.

ABSTRACT: Stemphylium blight (SB) is a major biotic stress that poses a potential threat to total yield loss in lentils. In this context, a comparative study was devised on the biochemical and physiological changes that may occur in six tolerant/resistant and six susceptible/highly susceptible lentil genotypes that were inoculated with the SB pathogen. Pathogen inoculation significantly reduced total chlorophyll and relative leaf water content across all genotypes, with the greatest reduction observed in susceptible genotypes. The recorded membrane stability index indicated significant membrane damage due to pathogen inoculation, particularly in susceptible genotypes. Similarly, the proline, total soluble protein, total soluble sugar, total phenol, and ascorbic acid contents increased several-fold i
