摘要
对长白山5种槭属植物的光响应参数、光谱反射率、光谱反射指数及色素含量进行对比研究,分析植物生理生态的异同点,探索光合与反射光谱特性之间的联系.结果表明:白牛槭(Acer mandshuricum)最大光合速率(Amax)和光饱和点(LSP)都显著高于其他4种槭属植物(P<0.05),其对林下光环境的适应性最强;550 nm左右的光谱反射峰可以作为区分不同树种的依据;白牛槭叶绿素归一化指数(ChlNDI)和光化学反射指数(PRI)均显著高于其他4种槭属植物(P<0.05);5种槭属植物的ChlNDI均与其叶绿素含量呈正相关,且与Amax有一定联系.
This research compared the light response parameters, spectral reflectance, spectral reflectance indices and pigment content of five Acer species in the Changbai Mountain to analyze the differences and similarities of physiological and ecological characteristics among species, and to explore the relationship between photosynthetic and spectral reflectance characteristics. The results showed that A. mandshurieum was the most adaptable species to the understory light environment with maximum photosynthetic rate （Amax and light saturation point （LSP） significantly higher than the other four Aeer species （P 〈 0.05）. There was a spectral reflectance peak around 550 nm, which can be used to detect different species. Both chlorophyll normalized difference index （ChlNDI） and photochemical reflectance index （PRI） ofA. mandshuricum were significantly higher than the other four Acer species （P 〈 0.05）. The ChlNDI of five Acer species are positively correlated with chlorophyll content, and also related to the Amax Fig 5. Tab 1. Ref30
