引种桉树苗期的抗寒性分析
The Analysis of Cold Resistances of Introduced Eucalyptus at the Seedling Stage
摘要
Abstract
In this paper, to screen out Eucalyptus species which are fast- growing and cold -resistant ability for cultivation in Jiangxi province, especially in Ganbei area of Jiangxi province, their physiological reaction under low temperature stress and their morphological change after freezing injury in Eucalyptus seedling are studied.The relative electrical conductivity and MAD content of Eucalyptus were tested and analyzed with 7 one - yea - old leaves of Eucalyptus under controlled low temperature treatments.The semi - lethal temperature was determined by using Logistic equation fitting for inflection point value.The results showed that the relative electrical conductivity, MDA content increased with the lowering of the treating temperature.The cold resistance of Eucalyptus species has significant difference.It is concluded that the cold resistance order of the seven Eucalyptus at the seedling stage was E.camphora ＞ E.dunnii ＞ E.dorrigoensis ＞ E.cypellocarpa ＞ E.camaldulensis ＞ E.grandis ＞ E.saligna.E.camphora and E.dunnii can be planted experimentally for their cold resistance in Ganbei area of Jiangxi province.关键词
