摘要：

采用针刺、层积、双氧水（H2O2）法、硝酸钾（KNO3）法和赤霉素（GA3）法对酸浆种子进行处理，研究不同处理对酸浆种子萌发的影响。结果表明：低温层积40天可有效地打破酸浆种子的休眠；赤霉素处理是打破酸浆种子休眠最为快速有效的方法，解除酸浆种子休眠的最佳浓度为0.08%；而针刺法、KNO3法和H2O2法对酸浆种子的解除休眠作用并不明显。说明酸浆种子休眠的主要原因是胚存在后熟作用且种子内部可能存在萌发抑制物质，而种皮的机械束缚不是抑制酸浆种子萌发的原因。

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.
