The plants of mustard (Brassica juncea L.) were treated with 0, 25 and 50 ΜM gibberellic acid (GA3) at three fully developed leaf stage (30 d after sowing). Effect of GA3 on carbonic anhydrase activity, photosynthetic rate, leaf area index and dry mass was studied at 50, 70 and 90 d after sowing. At harvest 1000 seed mass, pod number and seed yield were recorded. GA3 treatment (50 ΜM) enhanced all the characteristics studied.
