Leaf frost sensitivity and percentage of electrolyte leakage of the evergreen woody species in Tiantong region, Zhejiang Province

Abstract

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.

Key words: relative conductivity, cold resistance, life form, evergreen broad-leaved forests
