| Abstract: | The effects of heat shock (HS) pre-treatment on the response tobenzyladenine were studied in two plant model systems (1) retardation ofsenescence of Arabidopsis thaliana L. Heyhn rosette leavesand (2) induction of greening of detached Cucurbita pepoL.cotyledons. N6-benzyladenine (BA) retarded senescence of rosetteleaves of Arabidopsis thaliana (L) Heyhn and briefpre-treatment with HS (3 at 37 )essentially enhanced this cytokinin effect. BA stimulated cotyledon greening inCucurbita pepo L due to the activation of chlorophyllsynthesis. Brief cotyledon pre-heating at moderate temperatures (3 at 33–35) also enhanced thiscytokinin effect. |
