✦ Synopsis

Inclusion of IAA in the vase water had little effect on leaf yellowing in cut flowering branches of Alstroemeria pelegrina L . while kinetin delayed leaf yellowing at 10 -'M (continuous treatment) . Chlorophyll was effectively retained by 10 -'M gibberellic acid (GA) in the vase water or by a 20h pulse at 5'C with 10-1/10-4 M GA . After 16h of 14 C-GA, uptake at 20'C relatively high levels of 14 C were found in leaves and low levels in stems and flowers . After this treatment about half of the 14 C-GA, in leaves was metabolized into unknown compounds .
