摘要：Cherry (Cerasus Mill.) species are important agricultural crops with high economic and ornamental values. The seeds of stone fruits have a long dormancy period after harvest, which cannot germinate and grow until the dormancy has been broken. In order to break the dormancy and speed up the gremination of cherry seeds, we studuied the effect of GA3 treatment on the dormancy-breaking and germination rate of Chinese cherry and sweet cherry seeds without cold stratification. The results showed that GA3 treatment significantly increased the germination rates of cherry seeds, reaching the maximum value of 64%, 24% and 40% at the concentration of 100 mg•L−1 of GA3 for cultivated and wild Chinese cherry, and sweet cherry. In addition, GA3 treatment obviously speed up the germination index of cherry seeds, reaching the maximum value when immersing seeds with 100 mg•L−1 of GA3. Therefore, it is necessary to cultivate cherry seedlings by GA3 treatment.
