Description The present investigation had been done to study role of biochemical components in
bacterial blight ( Xanthomonas axonopodis pv. cyamopsidis ) resistance in clusterbean.
Clusterbean crop (cv. HG563, FS277, PNB, C. serrata) was raised in pots filled with 5 kg
of sieved sandy soil in a naturally lit net house. Two sets of 15 pots of each genotype were
maintained. One set was kept as control and another set was inoculated with Xanthomonas
axonopodis bacterial suspension at 30 - 35 days after sowing (DAS) and humidity was
maintained before and after inoculation. Morphological parameters like fresh and dry
weight of leaves and shoot decreased with infection but increased with advancement stages.
Chlorophyll, non- structural carbohydrate and crude protein content decreased in inocul ated
leaves as compared to uninoculated one . Oxidative enzymes activity (PPO, POX, PAL and
TAL), phenolic content and structural carbohydrates (ADF, Cellulose, Lignin and Silica)
increased in inoculated leaves. From the present study it may be concluded th at biochemical
constituents - like lignin, total phenols, flavanols, peroxidase, PAL, TAL, PPO and catalase
might plays an important role in bacterial blight resistance in clusterbean.
