Abstract

Abstract Spraying chrysanthemums at pinching with N 6 benzyladenine (BA) 400 ppm and 6-benzylamino)-9-(2-tetrahydropyranyl)-9H-purine (PBA) 200 ppm significantly increased branching, while other chemicals and lower BA concn less consistently stimulated larger numbers of branches than untreated plants. The chemicals inhibited stem elongation, but only BA caused a significantly shorter stem. Ethephon delayed flowering 10 or more days for all cultivars, and BA (400 ppm) spray of stock plants prevented or delayed rooting of cuttings taken 0 to 4 weeks after treatment. Sprays of BA, PBA and ethephon applied at pinching improved branching more than treatment 2 weeks before or 2 weeks after pinching.
