苹果梨优良授粉品种的选择

以苹果梨为研究对象,采用4个河北梨、5个延边当地梨为授粉品种,比较了不同授粉品种在苹果梨上产生的果实直感效应.结果表明:各组合的坐果率几乎都达到了100%.不同授粉树对苹果梨果实性状的影响差异很大,经新复极差法检验,差异达显著水平.综合考虑,可用蜜梨、京白梨作授粉树,生产上结合喷施膨大剂以提高单果重,也可用鸭梨、雪花梨做授粉树,同时结合喷施增糖剂提高果实含糖量.以期为提高苹果梨果品质量和经济效益提供有效的理论依据.

The Choice of Excellent Pollinated Varieties in Pingguoli

In this study,Pingguoli was used as an objection,and metaxenia effect was compared with different pollinated varieties,which were collected from four pear varieties in Hebei and five pear varieties in Yanbian respectively.The result indicated:The fruit setting rate in each combination almost added up to 100%.But there was significant difference on fruit character of Pingguoli produced by different pollinated varieties based on LSR test.In all,Mili,Jing Baili can be used for pollination of Pingguoli combined with sprinkling N-(2-chloro-4-pyridyl)-N'-phenylurea(CPPU)for improving single fruit mass,as well as Yali,Xuehuali were pollinators combined with sprinkling increasing sugar content for improving sugar of fruit.It will provide valuable foundation for improving fruit quality and economic benefit in Ping guoli.
