樱桃结果母枝直径与开花习性的相关性分析

Correlation Analyses on Bearing Shoot Dameter and Flowering Habit of the Cherry

为了探讨影响樱桃[Cerasus pseudocerasus（Lindl.）G.Don]开花习性的内在因素及机理,研究了樱桃结果母枝直径与开花习性的相关性。结果表明,樱桃结果母枝直径与结果母枝长度和总芽量之间呈高度正相关,与叶芽量、4朵花芽量和4朵花量之间呈显著正相关,与萌芽率、3朵花芽量和3朵花量之间呈显著负相关,与2朵花芽量、总花芽量和2朵花量之间呈低度负相关,与总花量呈负相关。作图分析结果表明,樱桃结果母枝直径以4.4-6.5 mm最好,其次以6.5-7.3 mm较好;回归分析结果表明,樱桃结果母枝直径与结果母枝长度、总芽量、叶芽量、萌芽率、2朵花芽量、3朵花芽量、4朵花芽量、总花芽量和总花量等指标的回归曲线都符合二次回归方程。建议可以通过培养优质枝梢来提高花的质量,通过调查樱桃结果母枝直径来预测各类花芽量和开花量等指标。

In order to explore the inner factors and its mechanism of cherry[Cerasus pseudocerasus（Lindl.） g. Don] flowering habit,the correlations of cherry bearing shoot diameter and flowering habit were conducted. Results showed that, cherry bearing shoot diameter had highly positive correlation with branch length and the total amount of bud,and significantly positive correlation with leaf bud amount, four flower bud amount and four flower amount,and significantly negative correlation with three flower bud amount and three flowers, and lowly negative correlation with the two flower buds amount,total flower bud amount and two flower amount, and negative correlation with the total flower amount. The mapping analysis results showed that,cherry bearing shoot diameter for 4.4-6.5 mm was the best, and the diameter for 6.5-7.3 mm was better; The results of regression analysis showed that, cherry bearing shoot diameter and branch length, total amount of bud and leaf bud ,two flower bud amount,three flower bud amount, four flower bud amount ,total amount of flower bud met the quadratic regression equation of the regression equation. It was suggested that,by cultivating high quality branch to improve the quality of the flowers,by investigating the cherry results female branch diameter as well as to predict all kinds of flower bud flowering index etc.
