Abstract: The mature leaves of two Lichi cultivars, Heiye and Huaizhi as materials, the correlations between leaf area and leaf perimeter, leaf length, leaf width, leaf length ? leaf width were analyzed, as well as the correlations between leaf weight and leaf perimeter, leaf length, leaf width, leaf length ? leaf width, leaf area. The results showed that, the leaf area of Heiye and Huaizhi could be estimated by leaf perimeter, leaf length, leaf width and leaf length ? leaf width, the estimation by leaf length ? leaf width was the most accurate. The leaf weight of Heiye could also be estimated by four leaf shape indices and leaf area, the estimation by leaf length was the most accurate. The estimations of leaf weight of Huaizhi by all the leaf shape indices were not accurate.

Key words: Heiye, Huaizhi, leaf area, leaf weight
