Abstract: ObjectiveThis study investigated correlation between bearing shoot and flower formation of different blue-berry varieties,in order to provide reference for blueberry cultivation in Guangxi. MethodThree blueberry varieties from Tian'e county, Guangxi were used as materials(Misty,Legacy and Premier). Length, diameter, leaf number, lateral bud number, terminal bud number and total bud number of the longest and the shortest bearing shoots were assessed. Cor-relation between the characters as well as correlation between the characters and flower formation were analyzed. ResultAccording to regression analysis,regression equation for Misty total bud number((y)), shoot length(x1) and leaf number(x2) was(y)=1.632+0.052x1-0.026x2, regression equation for Legcy total bud number((y)), shoot length(x1) and shoot diame-ter(x2) was (y)=1.061+0.009x1+0.152x2, regression equation for Premier total bud number((y)), shoot leaf number(x1),shoot diameter(x2),leaf number(x3) was(y)=-3.201+0.086x1+0.267x2+0.360x3. Correlation analysis on the characters showed that,blueberry shoot length,shoot diameter and leaf number were significantly correlated(P<0.05, the same below); to-tal bud number, shoot length,shoot diameter and leaf number were significantly correlated. But the correlation coefficient differed for different varieties. ConclusionLength, diameter and leaf number of blueberry bearing shoot have significant influence on total bud number. In actual planting, bearing shoots quality and total bud number can be increased through controlling shoot length, shoot diameter and leaf number via proper pruning and fertilization. In this way, the yield and quality of blueberry can be improved.
