摘　　要：应用相关与回归分析方法，对春播长茄品种（F1）幼苗叶面积的测定结果表明，茄子幼苗叶长、叶宽与单株叶面积之间存在极显著的正相关，第4叶位单叶面积与单株叶面积间的相关最为密切，因而以其回归方程作为茄子幼苗叶面积的无破坏性速测方法是简便可行的。The leaf areas of young plants of long eggplant variety (F1) sowed in Spring were measured and analysed with correlation and regression. The results showed that there were highly significant positive correlations between leaf length, leaf width and total leaf area of the whole plant. The closest correlation is between the 4th nodal leaf area anci total leaf area of the whole plant. Thcrefore, using their regression equation as a no harm quick measurment method is simple and feasible.
