摘要
为了研究文冠果的结果习性,对其修剪提供理论依据,对文冠果结果母枝的长度、顶端直径、基部直径进行了测定,并统计了结果母枝上的枝条数、结果枝数、结果枝的长度,顶端直径、基部直径、可孕花数、不孕花数、坐果数、单果重、果径、结实量、种子重,进而对文冠果母枝主要性状因子间的相关性进行了分析。结果表明:结果量与母枝相关性最大的性状因子是结果枝数,相关系数达到0.567,说明文冠果母枝上的结果枝数与结果量关系密切。与结果枝相关性较大的性状因子是可孕花数、结果枝顶端直径和基部直径,相关系数分别达到0.823、0.669、0.534,表明文冠果壮枝结果。通过研究产量和结果枝、结果母枝直径之间的关系表明,顶端直径达到4 mm以上、基部直径达到5 mm以上的结果枝;顶端直径达到7 mm以上、基部直径达到9 mm以的结果母枝才能有效的坐果,这对制定合理的整形修剪方案有重要意义。
In order to study bearing habit of Xanthoceras sorbifolia Bunge and provide theory basis for its pruning, length, basal diameter and tip diameter of mother branch were measured, and number of shoots, fertile floret, infertile floret, and fruitlet, single fruit weight, fruit width, burliness quantity and seed weight were counted. The results showed that the correlation coefficient of the number of bearing shoots is the largest among all mother branch characters, up to 0.567,so fruit quantity was closely related with number of beating shoots. The fertile floret, tip diameter and basal diameter of bearing branch had significant correlation with the number of fruitier, up to 0.823,0.669,0.534,showing that vigorous branch can set more fruit. The relationship between yield and diameter of bearing shoots and mother branches showed that bearing shoots with top diameter over 4ram,basal diameter over 5 mm and mother branches with top diameter over 7 mm,basal diameter over 9 mm could set fruit effectively, These results had great significance for developing a reasonable program for pruning.
