摘要:采用电导法对南亚热带的马占相思、大叶相思、厚荚相思的幼苗在树种和种源2个层次上的耐寒性进行了评估,并进行了排序。结果表明:在树种和种源层次上,3种相思耐寒性变异均达极显著差异;马占相思的低温敏感区为6℃,大叶相思和厚荚相思的低温敏感区为0~3℃;最耐寒的马占相思种源是17703,大叶相思种源是19244,厚荚相思种源是17562和16598。
This paper evaluated the ability of cold resistance of three Acacia species coming from south subtropical areas and sequenced the cold resistance of the provenances on the basis of electrical conductivity. The results showed that there was very significant diference for cold tolerance among the three Acacia species and their provenances. The sensitizing range of low temperature for A. mangium, was 6 ℃, and 3 -0 ℃ for A. auriculaeformis and A. crassicarpa. The strongest provenances of A. mangium, A. auriculaeformis and A. crassicarpa were 17703, 19244, 17562 or 16598.
