油茶结果枝与成花相关性研究

Correlation between Bearing Branch and Flower Formation in Camellia oleifera

以赣无系列5-6年生油茶林为研究材料,通过调查分析其结果枝分布、长度、直径、叶片数,并分析与成花的关系。结果表明,在树冠垂直方向上结果枝主要分布在40-99 cm区域,占总量的80%;油茶结果枝长度与成花有密切关系,花芽数量最多在20-60 mm范围内,其中40-60 mm花芽数量约占总体的37%;结果枝直径在2.0-2.3 mm花芽数量最多,其分布规律呈橄榄型;叶片数以5-7片的花芽数量居多。相关性分析表明,结果枝长度、直径及叶片数均与花芽数量呈极显著相关性。

The 5～6 a Camellia oleifera stands of ‘Ganwu’ series was made as study materials.The distribution,length,diameters and leaf number of bearing branch were studied and then its correlation with flower formation was analyzed.It indicated that 80 percent of bearing branches were distributed in the 40～99 cm region of the crown vertical direction.There was a close relationship between the length of bearing branch and flower formation.The flower bud was mass in the range of 20～60 mm＇s length,and 40～60 mm＇s number was accounting for 37 percent.So was it in the range of 2.0～2.3 mm＇s diameter whose distribution was olive type and 5～7 slices＇ leaf number.Correlation analysis showed that there were most significant correlation between the number of flower bud and the length,diameter and leaf number of bearing branch.
