Abstract :An experiment was conducted to assess the response of mung bean (Vigna radiata L. Wilczek) to 28-homobrassinolide (HBL) supplied to the seeds (1.0 µM) and/or to the foliage (0.01 µM) of the plants. Samples of the treated plant materials were assessed 30 and 50 days after sowing (DAS). It was observed that the activities of carbonic anhydrase (CA) and nitrate reductase (NR), leaf chlorophyll content (Chl), net photosynthetic rate (PN), stomatal conductance (gs), carboxylation efficiency (CE), dry mass (DM), pod number, and seed yield at harvest increased significantly over the control, irrespective of the mode of application. However, the plants raised by seed soaking also received foliar application of HBL generated maximum response. The order of response to HBL treatment was seed soaking + foliage application > foliage application only > seed soaking > control.Keywords : Brassinosteroids, carbonic anhydrase, nitrate reductase, stomatal conductance
