| 摘 要： | 对临安市3种桉树幼苗叶片叶绿素荧光特性进行研究,结果表明,自然低温下,各桉树表现出不同的适应性,总的来说,邓桉>柳桉>巨桉;自然低温(日最低气温-3.6℃)对柳桉和巨桉造成较大损害,而邓桉可通过维持相对较高的光化学效率,以及利用不断增加的qN来进行耗散,具有较强的抵抗低温胁迫伤害的能力。

| Abstract: | A research was conducted on chlorophyll fluorescence characteristics in leaves of three species of Eucalyptus seedling in Lin'an,Zhejiang province.The results showed that each species had different effect to natural low temperature.Generally speaking,the order of cold-resistance under natural temperature was E.dunnii>E.saligna>E.grandis.Natural low temperature had greater damage on E.saligna and E.grandis.However,E. dunnii was relatively higher cold resistant by relatively higher photochemical efficiency an... |
