[Abstract] To investigate relationship between tomato (Solanum lycopersicum) leaf chlorophyll content and Minolta SPAD-502 plus chlorophyll meter, we studied leaves at plant vegetative growth stage and reproductive growth stage, and conducted correlation analysis to establish most optimal function model. The results showed that the correlation of SPAD value and the content of chlorophyll a, chlorophyll b and total chlorophyll content were significantly correlated in tomato leaves. At plant vegetative growth stage, the optimal mathematic function for SPAD value and chlorophyll a, chlorophyll b and total chlorophyll were y = 0.0006x 1.924 ( r = 0.785), y = 0.0006 x1.8009 ( r = 0.756) and y = 0.2317e 0.0406x ( r = 0.869) respectively. At reproductive growth stage, the optimal function models were y = 0.0236x-0.0705( r = 0.856) for chlorophyll a, y = 0.2975e 0.0127x ( r = 0.793) for chlorophyll b and y = 0.0306x + 0.1443( r = 0.869) for total chlorophyll. All these data proved SPAD-502 can be an effective tool used for rapid and nondestructive estimation of leaf chlorophyll content in tomato.
