摘  要:
连续2年对蜜梨的花粉直感效应及不同栽培措施进行了比较试验,分析了9个不同授粉品种对蜜梨品质性状的影响。结果表明,蜜梨相关性状的花粉直感效应主要来自父本遗传因素的影响,而不同栽培措施的影响则相对微弱。授粉源选用综合性状优良的绿宝石、京白、杜梨和雪花梨品种,可不同程度的抑制果形、果柄变异,并相对提高单果重和可溶性固形物含量。

摘  要:
The compared tests on the mtaxenia and the cultivated practices of Mili pear were carried out, and also the effects on the quality characters of Mili pear pollinated by 9 cultivars were analyzed. The results indicated that the metaxenia was mainly affected by paternal genetic factors. While weakly by the cultivated practices. The pollens from Emerals. Jingbai, P.betulaefolia and Xuehua with good general characters could suppress the variances of fruit shape and pedicel of Mili pear and also improve the mean fruit weight and soluble solids content.
