Sucrose synthetase activity in developing kernels

--Shehalata B. Allagikar, S. E. Pawar, R. K. Mitra and N. K. Notani

Developing kernels of normal, standard sh1 and sh1-B kernels at 10, 14, 16 and 22 days after pollination were harvested. Enzyme activity was assayed in the direction of sucrose synthesis. Peak sucrose synthetase activity was noted at 16 days after pollination. However, the enzyme activity was markedly reduced in sh1-B and standard sh1 phenotypes. The peak activity for sh1-B and sh1 phenotypes was 57% and 40%, respectively, of the wildtype.
