摘要: 叶绿素是植物光合作用的色素,传统方法测定叶绿素一般采用分光光度法。本研究采用便携式叶绿素计SPAD-502测定落叶松人工林下4个主要阔叶树种绿色度(SPAD值)的季节变化,并与分光光度法测定的叶绿素含量进行相关性分析。结果表明,SPAD值与叶绿素含量具有显著的相关性,SPAD值能较好地反映树木叶绿素含量的变化。因此,使用叶绿素计测定树木的叶绿素含量是完全可行的,在一定条件下可代替叶绿素含量的直接测定。由于叶绿素计SPAD-502携带方便、测定简便、迅速,且不损坏叶片,应在林业研究中积极推广使用。

Abstract: Chlorophyll is the pigment for plant photosynthesis,and its traditional measuring method is spectrophotometry.In this research,portable chlorophyll meter SPAD-502 was used to measure the seasonal changes of the greenness(SPAD) of 4 broad-leaved tree species under larch(Larix gmelinii) plantations,with the correlation between SPAD value and chlorophyll content measured by spectrophotometry investigated.The results showed that there was a significant correlation between SPAD value and chlorophyll content,indicating that SPAD value could well reflect the changes of chlorophyll content in tree foliage,and it was feasible to measure the chlorophyll content by chlorophyll meter instead of spectrophotometry.Chlorophyll meter SPAD-502 should be used broadly in forestry research because of its convenience to carry,simple and rapid measurement,and no damage to leaves.
