Activities of carbonic anhydrase and ribulose-1,5-bisphosphate carboxylase, and dry mass accumulation in Brassica juncea following defoliation

The effect of 30.% defoliation of shaded leaves in lower layers of plant was studied on activities of carbonic anhydrase (CA) and ribulose-1,5-bisphosphate carboxylase (RuBPC), leaf dry mass per unit leaf area, and plant dry mass of mustard (Brassica juncea). Removal of 30 % of leaves resulted in increased CA and RuBPC activities of leaves, and leaf and plant dry masses.
