摘    要:以亚热带常绿阔叶林中的常见种石栎(Lithocarpus glaber)为研究材料,测定了不同光强条件(100%、75%和50%自然光强)下幼苗叶绿素荧光参数及叶绿素含量,探讨了石栎生长对光强的适应性。结果表明,随着光照强度的减弱,石栎叶片的叶绿素含量上升,3种光强条件下叶片光系统Ⅱ的实际光化学效率(ΦPSII)、最大光能转化效率(Fv/Fm)和潜在活性(Fv/Fo)的季节变化规律相似,高光强下的ΦPSII、Fv/Fm和Fv/Fo值相对较小,说明石栎幼苗能适应较大的光强幅度,同时对低、弱光强有一定的抗逆性。

关 键 词:石栎  光强  叶绿素含量  叶绿素荧光特性

Abstract:Take subtropical evergreen broad-leaved forest of Lithocarpus glaber as experimental materials,measured at different light intensity(100%,75% and 50% natural light intensity) chlorophyll fluorescence parameters and seedling chlorophyll content and discussed the optical strong growth of Lithocarpus galber.The results showed that with the weakening of light intensity,Lithocarpus glaber leaf chlorophyll content increased,three kinds of light intensity to the next leaves the actual photochemical efficiency of photosystem PSII(ΦPSII),the maximum efficiency of conversion efficiency(Fv/ Fm) and light system Ⅱ potential activity(Fv/ Fo) curve similar to seasonal changes,high light intensity under the ΦPSII,Fv/Fm and Fv/ Fo were less than medium and low light intensity,which showed Lithocarpus glaber could adapt to a larger intensity range.At the same time,low light intensity was with a certain degree of resistance.
Keywords:Lithocarpus glaber  light intensity  chlorophyll content  chlorophyll fluorescence
