Paclobutrazol and bulb size effect on onion seed production

2009

E01116

A field experiment was performed in Mymensingh, Bangladesh, during 2005-06 to evaluate the effects of paclobutrazol (PBZ, 0, 20, 40 and 80 ppm) and bulb size (small, medium and large) of onion on the growth and seed production of onion cv. 'Taherpuri'. The PBZ application significantly decreased the plant height, number of tillers per bulb, number of leaves per plant and length of scape. The number of flowers, umbels per bulb, umbel diameter, 1000-seed weight and seed yield were not influenced by the PBZ concentrations used. The plant height, number of leaves per plant, length of scape, effective fruits per umbel, percentage of fruit set and seed yield were positively influenced by the bulb size of onion. Variable interactive effects of PBZ dose and bulb size for different traits were recorded.
