INFLUENCE OF TEMPERATURE ON BREAKING OF DORMANCY, GERMINATION SENSU STRICTO AND GROWTH OF APPLE EMBRYO: THERMAL OPTIMUM OF THESE PHENOMENA

An experimental model for distinguishing between breaking of dormancy, germination sensu stricto and growth of apple embryo was developed. The thermal optimum was found to be different for each step. The use of this model should allow a precise study of the mechanisms governing the three phenomena.
