Effect of hormones on growth and yield characters of seed crop of kharif onion (Allium cepa L.)

Effect of hormones on growth and yield characters of seed crop of kharif onion (Allium cepa L.)

Indian Journal of Plant Physiology 38(3): 193-196

Onion bulbs for production of a kharif seed crop were dipped in 150, 300 or 450 p.p.m. solutions of GA3, NAA or ethephon or in water for 6 h, dried and planted in the field. GA3 and NAA treatment increased plant height, number and size of leaves and number of umbels per plant at concentrations up to 300 p.p.m., whereas 450 p.p.m. was less effective. Ethephon decreased plant height, with the effect increasing with increasing concentration.
