以刺槐、白蜡及臭椿的种子为试验材料,探讨了不同温度处理对3种绿化树种种子发芽的影响。结果表明:3种树的种子在变温方式下的发芽能力比恒温下强。其中:快速变温处理种子的发芽率、发芽势、发芽指数、活力指数、发芽幼苗长度及发芽苗根长均比缓慢变温处理下的数值高。
The seeds of Robinia pseudoacacia, Ash and Ailanthus altissima were used to study the effects of different temperature treatments on the germination of three tree species. The results showed that the seed germination ability of three tree species was higher than that under constant temperature. Among them, the germination rate, germination potential, germination index, vigor index, germinating seedling length and germinating seedling root length of fast-heating seeds were all higher than those under slow temperature-changing treatment.
