Abstract:
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=0.0005x1.9829?(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=0.2202e0.0414x (r=0.870* *)，the optimal function model for ‘Japanese hard star’ as y=0.0279x+0.2453(r=0.720* *)
