新疆两个品系杂交杨叶绿素荧光生态适应性特征/Chlorophyll fluorescence characteristics of ecological adaptability two poplar species in the Xinj iang[J]
比较研究了新疆伊犁地区广泛栽植的两个品系的杂交杨Populus balsamifera L .(Da)和Populus euramericana cv(I-467)叶绿素荧光变化特征;揭示两个品系的杂交杨对特殊地理区域中强辐射等环境影响因子的内禀生态适应性.通过暗适应和光适应的荧光实验,表明两个品系的杂交杨暗反应下荧光变化相似,光反应下荧光变化存在明显差异.I-467将光合反应中心PSⅡ吸收的过剩光能以热耗散等非光化学过程消耗的能力大于Da,相应降低了用于光化学淬灭的份额.Da对光的敏感指数(S)和PSⅡ反应中心吸收的过剩光能(E)能均高于I-467.取消光照条件后,两个品系杂交杨叶绿素荧光系统最初均能以较快的速度恢复,恢复速度逐渐减慢.Da对强光的转化适应能力比 I-467高,I-467对弱光和快速的光变化的适应程度更强.实验结果表明Da对于强光的适应能力更好,对光能的利用率更高.因此Da更适合作为新疆强光辐射区伊犁河谷人工速生丰产林树种进行造林
