COMPARISON OF TWO STRATIFICATION METHODS FOR SEEDS OF THREE PEACH ROOTSTOCKS CLONES

Seeds of three peach rootstock clones: PWM (Manchurian peach), BND 3 and BND 4, were chosen for the experiment.
Stratification was started on 20 December 2000 in a peat substrate, after soaking the pits for 24 hours in a 0.1% Benlate solution.
Two methods of stratification were used: 1) The traditional method (in a cold store at a constant temperature of 4^oC). 2) Warm-cool stratification (the first two weeks at room temperature, then in a cold store at 4^oC). Each combination represented 2000 pits (20 replications x 100 pits). The number of split pits and germinated seeds was counted every 10 days.
After 120 days of stratification, the average percentage of germinated seeds obtained in the warm-cool method reached 38.4, in comparison with only 24.4% in the traditional one.
