平欧杂交榛枝条主要性状因子间的相关分析

Correlation analysis among main branch characters in hybrid hazel

为了研究平欧杂交榛主要品种的结果习性,对平欧杂交榛4个品种结果母枝及结果枝的枝长、基部直径、顶梢直径进行了测定,并统计了结果母枝上的枝条数、结果枝数及叶片数和果苞数,进而对平欧杂交榛枝条各主要性状因子间的相关性进行了分析。结果表明:在4个平欧杂交榛品种结果母枝的各性状因子中,与单枝结实量相关性最大的性状因子是结果枝数,说明平欧杂交榛结果母枝上的结果枝数与单枝结实量关系十分密切;在"辽榛3号"、"达维"和"辽榛4号"结果枝的各性状因子中,与果序坐果数相关性最大的性状因子是顶梢直径,而在试材"辽榛7号"结果枝的各性状因子中,与果序坐果数相关性最大的性状因子却是基部直径,文中由此推知,平欧杂交榛果序坐果数与结果枝的粗度密切相关。

In order to study bearing habit of main varieties of hybrid hazel, length, basal diameter and tip diameter of mother branches and bearing shoots in four varieties of hybrid hazel were measured, and number of shoots and number of bearing shoots in mother branches and number of leaves and fruits were also counted. The results show that the correlation coefficient between number of bearing shoots and nut quantity of single branch is the largest in all mother branch characters of four varieties of hybrid hazel, so nut number of single branch is closely related with number of bearing shoots in mother branches. The correlation coefficient between tip diameter and nut number is the largest in all bearing shoot characters of Liaozhen No.3, Davey and Liaozhen No.4, but that between basal diameter of bearing shoots and nut number is the largest in Liaozhen No.7. It is obviously that the relationship between nut number and diameter of bearing shoots is close.
