Leaf yellowing of Alstroemeria hybrida L. ‘Rio’ and ‘Jacqueline’, as measured
by sphere spectrocolorimetry, was significantly delayed in vase life studies when
the ends of cut stems were immersed in solutions of BAP or GA3 immediately following
harvest. When BAP or GA3 was used alone at 50 mg·liter-1, foliage color and color
intensity did not diminish during 14 days of storage in tap water. BAP and GA3 also
showed interaction effects on leaf color, but little was gained by using combinations of
chemicals. Chemical names used: 6N-benzylaminopurine (BAP); gibberellin (GA3).
