不同防寒措施对引种的加拿大糖槭抗寒生理指标的影响

对引种的2年生加拿大糖槭苗分别进行稻草防护、窖藏处理,并以野外露地越冬生长的苗木为对照,研究不同处理的加拿大糖槭苗在生理及形态等方面对低温的反应,结果表明:在自然条件下的苗木形态指标不如稻草防护的苗木,窖藏的加拿大糖槭的苗木质量又优于稻草防护的加拿大糖槭,因此,对引种幼苗,最好保护方法是窖藏法。

Effects of cold resistance physiological indicators on different winterization measures for Acer saccharum

The 2-year-old Acer saccharum seedlings were processed by using straw protection or cache store respectively,and the open field was taken as the control to study the growth of the winter seedlings in order to show the different treatment response to low temperature in the aspect physiology and morphology.The results showed that the morphology index of natural seedlings under was not as good as that of the processed one,but the cache store was superior to the straw protection,therefore,for the introduced seedlings,the best protection way was cache store.
