目的阐明不同温度及种根大小对附子萌发及苗期性状的影响。方法用光照培养箱控制附子的发芽温度,观察不同温度下不同大小附子种根的发芽情况。结果 变温处理较恒温处理的附子种根发芽时间短,发芽率、发芽势和发芽指数均较高,小种根的发芽率、发芽势、发芽指数均高于大、中种根,苗期性状表现也较好。结论种根在10 g左右发芽的综合性能优良,早春应加强水分管理提高种根发芽率。 Objective To clarify the effects of different temperature and seedling size on the germination and seedling traits of Armeniaca. Methods The germination temperature of the aconite was controlled by a light incubator, and the germination of the roots of aconite with different sizes under different temperatures was observed. Results The results showed that the germination time, germination energy and germination index of A. przewalskii seedlings treated with isothermal treatment were higher than those of the other treatments. The germination rate, germination energy and germination index of ramet seed were higher than those of the large and medium seedlings Performance is better. Conclusion The comprehensive performance of seed germination of about 10 g is good. In early spring, water management should be strengthened to increase the germination rate.
