Abstract:

Using acupuncture treatment, stratification treatment, H2O2 treatment，KNO3 treatment and GA3 treatment to process Physalis alkekengi var. franchetii seeds, then compare influences of different treatment on germination of Physalis alkekengi var. franchetii seeds. The results showed that: stratification for 40 days can break the dormancy of Physalis alkekengi var. franchetii seeds effectively; GA3 treatment was the most rapid and effective method to break Physalis alkekengi var. franchetii seeds dormancy, and the best concentration was 0.08%; whereas, acupuncture treatment, KNO3 treatment and H2O2 treatment had no obvious effect on breaking Physalis alkekengi var. franchetii seeds dormancy, it turned out that the dormancy of Physalis alkekengi var. franchetii seeds was mainly caused by the after-ripening of embryo and there maybe inhibitors in seeds, and the mechanical restraint of the seed coat wasn’t the important reason why there was a long dormancy period in Physalis alkekengi var. franchetii seeds.
