Abstract: Two leaves and one new period was the sensitive period of melon to low temperature and low light condition, which period was always used to chlorophyll content determination and tolerance material selection. There were three leaves in this period, but no research mentioned about the definite measure leaf. To understand these and select the suitable measure leaf for chlorophyll content prediction by SPAD value determination, the chlorophyll content and SPAD value of three leaves of two leaves and one new period melon were collected and analyzed. The three leaves from bottom to up (Y1, Y2 and Y3) at different position of melon inbred line of P148 was selected to determinate and analyze the variation and correlation of SPAD value and chlorophyll content in two leaves and one new period by One-Way-ANOVA, Correlation and Regression program of SPSS 13.0 soft, respectively. The SPAD value and chlorophyll content were increased with increasing of leaves position. The Y3 showed the higher SPAD value and chlorophyll content than Y1 and Y2 significantly. The correlation between SPAD value and chlorophyll content was reduced with increasing of leaves position.The SPAD value and chlorophyll (a+b) content of Y1 had highest R value, the regression equation was established: y(Chla+b)=0.032x(SPAD)-0.141,R2=0.699. The first leaf was selected to determinate the SPAD value for chlorophyll content prediction to mass screen the low-temperature-and-light tolerance melon.
