摘　　要：作者以20个蓝莓品种为试验材料,调查并分析不同蓝莓品种结果枝的长度、粗度与花芽数量,以及它们之间的相关性。结果表明,不同蓝莓品种结果枝长度、粗度不同,结果枝结构类型差异较大,且不同蓝莓品种结果枝上的总花芽数量不同,坐果率也不同。进一步相关性分析表明,不同蓝莓品种结果枝长度、粗度与花芽数量之间呈现显著或极显著相关性。有5个蓝莓品种结果枝越长、越粗,花芽数量越多,其余15个品种则出现不同结果。综合评价表明,蓝莓不同品种花芽数量受结果枝长度和粗度的影响,生产中应综合考虑不同蓝莓品种性状,通过品种选择或栽培技术措施来保留或培养适宜长度和粗度的结果枝,以利于产量的增加和品质的提高。The author used 20 blueberry var ieties as experimental materials,analyze the length,thickness,and number of flower buds of different blueberry varieties,as well as their correlation.The result showed that the length and stem diameter of branches of different blueberry varieties,and the structure types of bearing branches were quite different.Furthermore,the total flower bud numbers of tree in different varieties were different,and the fruit setting rate were also different.Correlation analysis further supported the notion that the length and stem diameter of branches were significantly or very significantly correlated with flower-bud numbers.5 blueberry varieties with longer and thicker branches,there were very significantly flower-bud numbers.But the other 15 varieties had different branches types with length and stem diameters.The comprehensive evaluation showed that flower-bud numbers of blueberry varieties were affected by the length and stem diameter of branches.Different blueberry varieties should be comprehensively considered of the branches with suitable length and diameter in production through variety selection or cultivation techniques in order to increase yield and improve quality.
