Abstract

Chlorophyll (Chl) and total soluble protein decreased and proteolytic activity increased over a 12-day period during dark-induced senescence in detached leaves of Tara, a yellowing cultivar (Y) of Dendranthema grandiflora. In Boaldi, a non-yellowing cultivar (NY), Chl and soluble protein remained near initial levels and little change in proteolytic activity was observed. Sodium dodecyl sulfate polyacrylamide gel electrophoresis of soluble proteins showed no major differences in banding patterns between the two cultivars at day 0; however, all of the resolved proteins were diminished in Tara by day 12. On the other hand, in NY Boaldi, the intensity of the protein bands did not change over the 12-day period. Attached and detached leaves exhibited similar senescence patterns for each cultivar. Ethylene (100 µl l-1) accelerated the rate of Chl loss in detached leaves of Tara, but had no effect on Boaldi. These observations suggest that Boaldi is a stay-green genotype, possibly a functional type. The results are discussed in relation to the role of ethylene in chrysanthemum leaf senescence.
