The Effect of GA3 Application on Flowering and Seed Production in Onion1

Year: 1980

Type: article

Abstract: Mother bulbs of onion ( Allium cepa cv. Grano) were treated with gibberellic acid (GA 3 ) at 0, 50, 150 and 450 ppm upon emergence of first flower stems. A single application at 50 ppm shortened by one-half the time required for emergence of 80% of floral stems and increased the uniformity in height of the flower stalks. GA 3 -treated plants produced larger and more productive umbels, resulting in an increase in seed yield by about 30%. There was no difference in seed viability between treatments.
