新疆若干杏品种叶、枝和果实品质与叶面积的相关分析

对8个新疆杏品种的叶片主脉长度、新梢长度、果实重量、可溶性固形物与叶面积之间进行了相关性分析。所有供试品种的叶片主脉长度与叶面积之间呈非线性幂函数回归关系．新梢长度与叶面积之间呈线性回归关系，相关(指)系数在0．01水平下都达到极显著水平，二者与叶面积之间皆呈极显著正相关；多数品种的叶果比，与平均单果重呈显著正相关，而与果实可溶性固形物的相关性不显著。就叶果比的大小对杏树的产量和果实品质的影响进行了讨论。

Analysis on the correlation between leaf, new branch, fruit quality and leaf area of apricot cultivars in Xinjiang

In the experiment,the study and analysis were conducted on the correlations between the length of main vein,new branches,fruit weight,soluble solid and leaf area of about 8 Xinjiang apricot cultivars.All relationships between main vein length and leaf area of all apricot varieties that show nonlinear math.power regression function, new branch length and leaf area present the line regression relation. All the correlated(index) coefficients come up to significant level under the 0.01 level, which present the correlations between main vein length, new branch and leaf area are significant positive correlation. The relationships between leaf-fruit ratio and the average single fruit weight of most varieties show significant positive correlation and soluble solid has not significant correlation. The effect of leaf-fruit ratio on the fruit yield and quality of apricot was discussed.
