为了探讨影响樱桃果实品质变化的相关性及机理,并为制定科学的樱桃栽培技术提供理论依据。历经3年(2013—2015),以10~12年生“黑珍珠”樱桃品种为试材,对樱桃不同结果母枝直径与果实品质变化的相关性进行了调查研究。结果表明:1)相关系数相关性,结果母枝直径与果实横径和果汁含糖量呈显著负相关,与果柄长度呈显著正相关;呈显著差异性,结果母枝直径与果汁含糖量、果柄长度、叶片长度、叶片宽度和叶柄长度等指标之间都存在极显著差异水平,与果实横径和叶柄直径等指标之间存在显著差异水平。2)回归分析表明,结果母枝直径与果实单果重、果实纵径、果实横径、果汁含糖量和果柄长度的方差分析结果,Significance F分别为0.788 6、0.806 7、0.267 3、0.133 1、0.087 2,即结果母枝直径与果实单果重和果实纵径等指标之间存在极显著差异水平,与其它指标之间不存在显著差异水平;对残差曲线、观察值曲线、预测值曲线和正态概率图曲线等内容做二次曲线回归方程和直线回归方程的比较分析,其结果都符合二次曲线规律。建议通过调查结果母枝直径和回归方程来预测果实单果重、果实纵横径和果汁含糖量等内容;可以把培养结果母枝直径大小作为生产优质果品的主要依据之一。
In order to discuss the correlation and mechanism that affect the quality of cherry fruit, and to provide a theoretical basis for the development of scientific cherry cultivation techniques. After 3 years (2013-2015), 10-12-year-old black pea cherry varieties were used as materials to investigate the correlation between the diameter of branch of cherry and the change of fruit quality. The results showed that: 1) Correlation coefficient, the results of the diameter of the branch and the fruit diameter and fruit juice sugar content was significantly negatively correlated with the length of the stalk was significantly positive; significant difference, the results of the mother branch diameter and sugar content There was a significant difference between the indexes of stem length, leaf length, leaf width and petiole length, and there was a significant difference between the index and fruit diameter and petiole diameter. 2) The regression analysis showed that the results of variance analysis of the results of the branch diameter and fruit fruit weight, fruit length, fruit diameter, fruit juice sugar content and fruit stalk length, Significance F were 0.788 6,0.806 7,0.267 3,0.133 1,0.087 2, that is, there is a significant difference between the diameter of fruit branch and the fruit weight and fruit length, and there is no significant difference between the diameter of fruit branch and other indicators; the residual curve, the observed value curve, the predicted value Curve and normal probability curve curves and other content of the quadratic curve regression equation and linear regression equation of comparative analysis, the results are in line with the law of the quadratic curve. It is suggested to predict fruit weight, fruit vertical and horizontal diameter and fruit juice sugar content based on the results of the study on branch diameter and regression equation. One of the main basis for the production of high-quality fruit can be the diameter of the branch.
