摘　　要：以"粉艳红"和"日本硬星"2个不同类型的番茄品种叶片为试材,分别采用SPAD-502叶绿素仪与分光光度法测定2个品种番茄叶片的SPAD值、叶绿素含量,分析其相关性并建立拟合方程。结果表明:2种番茄叶片的SPAD值与叶绿素a、叶绿素b、总叶绿素含量的相关性均为极显著。就SPAD与叶绿素a的相关性而言,"粉艳红"的最优函数模型为y=0.0005x1.9829(r=0.902**),"日本硬星"的最优函数模型为y=0.0204x+0.059(r=0.669**);就SPAD值与叶绿素b的相关性而言,"粉艳红"的最优函数模型为y=0.0883e0.0403(r=0.758**),"日本硬星"的最优函数模型为y=0.2738e0.0144x(r=0.635**);就SPAD值与总叶绿素含量的相关性而言,"粉艳红"的最优函数模型为y=0.2202e0.0414x(r=0.870**),"日本硬星"的最优函数模型为y=0.0279x+0.2453(r=0.720**)。Taking leaves of two kinds of tomato varieties of ＇Powder red＇ and ＇Japanese hard star＇ as materials, using the SPAD-502 chlorophyll meter and spectrophotometry to determine two kinds of tomato leaf SPAD value and chlorophyll content,their correlation analysis and the fitting equation were established. The results showed that two kinds of tomato leaves,the correlation of SPAD value and the content of chlorophyll a, chlorophyll b, total chlorophyll content were significantly correlated. In terms of the correlation between SPAD and chlorophyll a, optimal function model for ＇Powder red＇ was y=0. 0005.3219829 （r=0. 902＊＊ ） ,the optimal function model for ＇Japanese hard star＇ as y=0. 0204x＋0. 059（r= 0. 669＊＊ ）. On the SPAD value and the correlation between chlorophyll b,optimal function model for , Powder red＇ was y=0. 0883e0.0403 （r=0. 758＊＊ ）,the optimal function model ＇Japanese hard star＇ was y=0. 2738e0.0144x（r=0. 635＊＊ ）. On the SPAD value and the correlation between total chlorophyll content was concerned, the optimal function model for ＇Powder red＇ was y：0. 2202e0.044x （r=0. 870＊＊ ） ,the optimal function model for ＇Japanese hard star＇ as y=0. 0279x＋ 0. 2453（r=0. 720＊＊ ）.
