Curve Fitting for Relationships Between SPAD Readings and Leaf Chlorophyll Content of Different Litchi Varieties
In the present experiment,five litchi (Litchi chinensis Sonn.) varieties were employed.Relationship between chlorophyll contents and the chlorophyll meter readings (SPAD readings) were studied and the corresponding curves were fitted.For each variety,the best fitting curve was established,and its utility was asssessed.Among the four types of fitting equations,the power equation was the best.
