Abstract:

Specific activity of two hydrolytic enzymes viz., cellulase and polygalactouranase was assayed in the shattering and non-shattering zones of pod wall and lignin content in pod wall of soybean varieties at four harvesting stages viz., at physiological maturity, 5 DAPM, 10 DAPM and 15 DAPM. The cellulase enzyme activities was lowest at non-shattering zone of pod wall of the susceptible varieties as compare to the resistant varieties but highest at shattering zone of pod wall of the susceptible varieties indicating its role in pod shattering. Polygalactouranase enzyme activity was highest at shattering zone of pod wall of the resistant varieties than the susceptible varieties, protecting it from shattering. The activity of cellulase and polygalactouranase enzyme goes on increasing after physiological maturity onwards in both susceptible as well as in resistant varieties. The lignin content in pod wall of soybean varieties also goes on increasing after physiological maturity onwards in both varieties (Susceptible and resistant) but highest lignin content in pod wall of susceptible varieties.
