Abstract
Apple explants in continuous illumination at 24°C cultured on basic medium for 18 days increased their frost resistance from -4.4° to -10. 0°C. This acclimatization was accelerated by ABA. GA cultured explants showed growth increases during the first 10 days and a rapid loss of frost resistance.
A large increase in water soluble protein was found after ABA and GA treatments.
Four-month-old seedlings doubled their frost resistance when exposed to 0°C for 5 days, but ABA and GA sprays were not effective.
The increase in water soluble protein was not reflected in frost hardiness.
