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