Application

6-Benzylaminopurine (6-BA) stimulates RNA, RuDP-carboxylase, NADP-glyceraldehyde-3-phosphate-dehydrogenase, protein synthesis. Mode of action Synthetic cytokinin; little translocated. Used to stimulate the following effects: cell division; lateral bud emergence (apples, pears, oranges); basal shoot formation (roses, orchids); flowering (cyclamen, cacti); fruit set (grapes, oranges, melons); causes abscission of young fruitlets, leading to increased fruit size, stimulates flower bud formation and regular bearing in fruit trees. Inhibits senescence of rice seedlings. Enhances lateral bud break and lateral shoot growth, leading to fuller white pine trees. Also causes uniform bolting and increased seed production in spinach. Applied by foliar application, soaking, or painting. Its limited ability to translocate is utilised to restrict effects to the target part of the plant, by local application. Applied at 30 g/a for apple trees.
