摘要:
梨是世界四大水果作物之一,拥有特殊的自交不亲和特性。这种现象在蔷薇科中普遍存在,但关于不同品种的自交不亲和强度却鲜有报道。综合田间自花授粉套袋试验及花粉管原位荧光显微观察,对256个不同梨品种进行套袋处理、花粉管生长特性观察、自交不亲和性强度统计分类以及坐果率调查。结果显示:自交不亲和性较强品种的花粉管虽然有少量穿过柱头,但不能在花柱内进一步生长,表现为扭曲变形、花粉管杂乱无章,以及花粉管末端变粗膨大等现象。不同梨品种自交不亲和性强度R值参差不齐,所调查的大部分梨品种自交不亲和强度分布在强与中之间,分别占57.4%、33.6%,而自交不亲和性弱的只占9.0%,仅有闫庄鸭梨、秋荣、54S-135、金坠、大果黄花和晚秀7个品种。田间自花授粉坐果率调查发现,自交不亲和性强度为强与中的品种的结实率基本为0,弱自交不亲和性强度品种金坠、秋荣的结实率分别为61.4%、32.7%,但晚秀表现出自交不结实。研究结果不仅具有理论价值,而且有潜在的实践意义。
