摘  要:
为给苹果砧木种子处理提供技术依据 ,对几种野生苹果砧木的种子进行解除休眠的低温需求试验。结果表明 :在 3℃的低温条件下 ,湖北海棠 (Malus hupehensis Rehd.)和三叶海棠 (Malus sieboldii Rehd.)的多数种子解除休眠需要的低温时数为 12 0 0 h以上 ,丽江山定子 (Malusrockii Rehd.)需要 15 6 0 h以上。不同地区野生状况下的三叶海棠种子解除休眠需要的低温时数有一定差异。

摘  要:
Requirement of low temperature on seeds of wild M. hupehensis Rehd., M. sieboldii Rehd.and M.rockii Rehd.breaking of dormancy was test. The results showed that requirement of low temperature(3℃) on seeds of M. hupehensis Rehd., M. sieboldii Rehd.and M. rockii Rehd. breaking of dormancy were 1 200h and 1 560h. Requisite time of low temperature on seeds breaking of dormancy is different to wild plant of M. sieboldii Rehd. in different ecological environment.
