以‘黑叶’和‘怀枝’2个荔枝品种的成熟叶片为材料，对叶周长、叶长、叶宽、叶长宽乘积与叶面积、叶重量之间的相关性进行回归分析。结果表明，‘黑叶’和‘怀枝’均可通过叶周长、叶长、叶宽和叶长宽乘积进行叶面积估算，其中以叶长宽乘积的估算效果最好；‘黑叶’可通过叶周长、叶长、叶宽、叶长宽乘积和叶面积估算叶重量，其中以叶长指标的估算效果最佳；‘怀枝’基于上述5个叶形指标进行的叶重量估算效果不佳。
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.
