Abstract
Apical dominance in newly budded plants of Cvs Apricot Silk, Peace, Alcc's Red and Golden Treasure was checked at an early stage using benzyl adenine (BA), 2,3,5 tri-iodobcnzoic acid (TlI3A), (2-chloroethyl) phosphonic acid (cthcphon) and chlormequat chloride (Cycocel). These treatments improved the commercial quality of the bush. Ethcphon and cycocel were better compounds for their use and led to the development of new shoots from the basal and axillary buds and from the bud union. Ethephon at 500 ppm with Tween-20 (1%) as a wetting agent caused significant increase in the number of shoots growing from the bud union in both the glasshouse and field-grown roses.
