Abstract

The influence of temperature (1-25 degrees C) and maturity on organ abscission promoted by a range of ethylene concentrations (0.3-100 mu l litre(-1)) was examined on stem explants of two Camellia cultivars ('Anticipation' and 'Donation'; C. saluenensis x C. japonica). Time to abscission of 50% of leaf and floral buds was measured. Leaves were most responsive during stem elongation following vegetative budbreak. In contrast, ethylene-responsiveness of floral buds gradually increased with maturity. Low temperatures (1-5 degrees C) reduced the rate of abscission response to ethylene at all concentrations, but with greatest effect at low concentrations (
