摘要：[目的]为探明油茶花粉直感效应和品种精确配比。[方法]以长林3号、长林4号、长林40号和长林53号4个良种为研究对象,采用人工授粉完全双列杂交试验,研究不同授粉组合下油茶坐果率、果实质量、种仁含油率和鲜果含油率的差异,同时按照混料设计优化油茶品种配置模式。[结果]不同授粉组合在油茶坐果率、果实质量、种仁含油率和鲜果含油率等方面均差异显著,异交授粉的各项指标均显著高于自交授粉。综合分析上述各项指标,长林53号的推荐配置授粉品种是长林4号,长林3号、长林4号和长林40号的推荐配置授粉品种均是长林53号。3个品种配置,采用长林4号(33.65%)+长林40号(26.18%)+长林53号(40.17%)时产油量最高。[结论]油茶在坐果率、果实质量、种仁含油率和鲜果含油率等方面存在花粉直感效应,利用花粉直感效应并结合实际生产情况,通过选择授粉品种以及品种的比例配置,促进油茶高产高效。
[Objective]To investigate the xenia effect of camellia oleifera pollen and the precise matching ratio of varieties.[Methods]The differences in fruit setting rate,fruit quality,seed kernel oil content and fresh fruit oil content of camellia oleifera under different pollination combinations were investigated in a complete double-row cross test using four breeds of‘Changlin3’,‘Changlin4’,‘Changlin40’and‘Changlin53’,and the configuration pattern of high yielding varieties of oil tea was screened according to the mixture design.[Results]Different pollination combinations showed significant differences in fruit setting rate,fruit quality,seed kernel oil content and fresh fruit oil content of camellia oleifera,and all indexes of cross-pollination were significantly higher than those of self-pollination.The recommended pollinator for‘Changlin53’was‘Changlin4’,and the recommended pollinator for‘Changlin3’,‘Changlin4’,‘Changlin40’was‘Changlin53’.The highest oil yield was obtained with the configuration of three varieties,‘Changlin4’(33.65%)+‘Changlin40’(26.18%)+‘Changlin53’(40.17%).[Conclusion]Camellia oleifera has xenia effect in fruit setting rate,fruit quality,seed kernel oil content and fresh fruit oil content,and the pollen direct effect is used to promote the high yield and efficiency of Camellia oleifera by selecting pollination varieties and the proportional configuration of varieties.
