摘　　要：以菜心的两个品种:"三月青"和"青柳叶"为试验试材,利用SPAD-502叶绿素仪与丙酮乙醇混合法对其叶绿素含量进行测定,以及对测量数据进行线性、对数、乘幂和指数函数的相关性比较分析,来探究菜心叶片SPAD值与叶绿素含量之间的相关性。结果表明:不同菜心品种的叶绿素a、叶绿素b、总叶绿素含量以及SPAD值都各不相同。通过相关性分析,发现叶绿素含量与SPAD值均呈现显著的相关关系。由此表明,可以利用叶片SPAD值很好地反映整个植株的叶绿素含量水平,通过建立方程式就可以由SAPD值计算出叶绿素的含量。此法简便易行,并且不损害叶片,可以保留植株的完整性。With two varieties of cabbage‘Sanyueqing＇and‘Qingliuye＇as experimental test material, their chloro-phyll content were determined by using SPAD-502 chlorophyll meter and mixing ethanol and acetone method. Thecorrelation between SPAD value and chlorophyll content of cabbage leaves was analyzed by comparison of linear,logarithmic, power, and exponential functions correlation. The results showed that chlorophyll a, chlorophyll b, totalchlorophyll content and SPAD values of different varieties of cabbage were different. Correlation analysis showedthat chlorophyll content and SPAD values was significantly related. It suggested that a very good response leafSPAD value with chlorophyll content of the whole plant. Through the establishment of the equation, chlorophyll con-tent could be calculated by the SPAD values. This method is simple, and does not damage the leaves, so the integri-ty of the plant can be kept.
