对北方地区引种的加拿大糖槭越冬状况的研究

Research on the Survived Winter the Condition on Acer saccharum Introduced in the North

该文研究了不同防护措施对2年生加拿大糖槭在沈阳的越冬情况、生理反应及对苗木形态和生长的影响。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要优于稻草防护的加拿大糖槭,因此,对引种的加拿大糖槭幼苗,在沈阳最好的越冬保护方法是窖藏法。

In this paper, the effects of different protective measures on hibernation, physiological responses, morphology and growth regarding the seedlings of the introduced 2 - year- old Acer saccharum in Shenyang were studied. The results indicated that： the morphological characteristics of seedlings in natural conditions were not so well as that protected by straws, the quality of Acer saccharum stored in caches was better than that protected by straws. Therefore, the best methods to protect the domesticated seedlings in Shenyang in winter were to be stored in caches.
