Summary:An experiment was conducted in the laboratory of Crop Botany Department of Bangladesh Agricultural University, Mymensingh, during the period from May 2003 to March 2004 to investigate the effect of GA3 and GABA on seed germination and seedling growth of brinjal, tomato and chilli. The concentrations of GABA were 0.16 mll.:1, 0.33 m1L-1, 0.66 mIL:1 and of GA3 were 25 mgL 1, 50 mgC, 100 mg1:1 and of water respectively along with a control where only water was used to treat seeds by soaking for 12 hours in prior to sowing on saturated tissue paper in petri-dishes. The experiment was laid out following RCBD design where each treatment replicated five times. Germination percentage of all the seeds treated with PGRs of above-mentioned concentrations was significantly higher over control. Seed germination was enhanced significantly in brinjal and tomato at 100 mgL" of GA3. Seedling growth (shoot length and root length) increased at 25, 100 mgl.:1 of GA3 and 0.33 mlL1 of GABA.
