Abstract

An experiment was conducted to investigate the effect of potato extract (PE) on seed germination and seedling growth of Vanda roxburgii in vitro, a local orchid. Potato extracts significantly enhanced seed germination and seedling growth . Among the concentrations, PE at 200 mlL -1 enhanced per cent germination from 17.2% (control) to 78.24% and was found to be the most suitable one for seed germination. It was also the best among treatments for production of viable protocorms as well as healthy seedlings from seeds. Growth of seedlings in respect of length of shoot, number of root per shoot and length of root per seedling was significantly enhanced in medium supplemented with 100 mlL -1 of PE. It may be concluded that PE at optimum concentration could be supplemented in medium for high percentage of seed germination and seedling growth of Vanda orchid.

Abstract

An experiment was carried out in the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, to investigate the flowering pattern, floral and pod abscission under untreated and GABA (mixture of GA3 and Abscissic acid) treated soybean and their trends concern to yield. The variety of soybean PB-1 (Shohag) was used in the investigation. GABA at 0.5, 1.0 and 2.0 mg L-1 of water with a control (only water) were used for foliar spray. Flower and pod initiation started from 54 and 60 DAS in all plants irrespective to GABA treatment. Flower production trend showed a deltoid pattern where pod production was gradually increased and slowed down at 74 DAS but not in GABA treated plant. The 4th node produced the highest number of flowers, then decreased and got zigzag pattern in upper nodes. GABA treated plants produced more nodes per plant and followed lower trend in flower and pod abscission indicated the efficacy of higher yield.
