Seeds ofVerbascum thapsus were imbibed on filter papers in Petri dishes and were exposed to a series of temperatures of 4°C→10°C→20°C→10°C→4°C in darkness. After each temperature treatment lasting one month, samples were removed and tested in light and darkness over a range of alternating temperatures. The results showed us that the dormancy state changes gradually according to the imbibition temperatures simulating the seasonal cycle. The ecological implications of the dormancy phases for the regulation of germination in natural conditions are discussed.
毛蕊花种子在培养皿中的滤纸上进行吸胀处理，并在黑暗中依次暴露于4°C→10°C→20°C→10°C→4°C的一系列温度下。每次温度处理持续一个月后，取出样本并在一系列交替温度下的光照和黑暗条件下进行测试。结果表明，休眠状态根据模拟季节循环的吸胀温度逐渐变化。本文讨论了休眠阶段对自然条件下种子萌发调控的生态学意义。
