酒用葡萄品种赤霞珠和梅鹿辄单叶面积分别与叶长和叶宽相关最密切，可用一元直线和曲线方程来估算，且以抛物曲线回归方程计算结果准确可靠。新梢叶面积与新稍粗度、叶片数目呈极显著正相关，可用其为自变量的多元回归方程来估算新梢叶面积。 The single leaf area of ​​wine grape Cabernet Sauvignon and Merlot was the most closely related to the leaf length and leaf width, respectively, which could be estimated by the linear equation and the curve equation. The parabolic regression equation was accurate and reliable. New shoot leaf area and the new slightly coarse, the number of leaves was extremely significant positive correlation can be used as an independent variable multiple regression equation to estimate the shoot tip area.
