浙江天童常绿木本植物的叶片相对电导率及抗寒性
Leaf frost sensitivity and percentage of electrolyte leakage of the evergreen woody species in Tiantong region, Zhejiang Province
摘要
Abstract
In this study, leaf percentage of electrolyte leakage was examined by using respectively 26℃ , 0℃ and - 5℃ temperate treatments, to reflect the leaf frost sensitivity for 59 evergreen woody plants in Tiantong region, Zhejiang province. The objective was to select frost-resistant woody plants for establishing frost-tolerant plantations. The results showed: (1) the most evergreen woody plants acclimatized themselves to 0℃, indicating few leaf damage; whereas,-5℃ treatment led to a significant increase of leaf percentage of electrolyte leakage for all plants, suggesting a heavy leaf damage; (2) among three dominant families of plants, the frost-resistance was higher in Lauraceae and Fagaceae than in Symplocaceae; and (3) evergreen broadleaf plants was more frost-resistant than conifer species. Therefore, the frost-resistant plants belonging to Lauraceae and Fagaceae families should be preference species in afforestation.关键词
