黄花梨授粉品种选配的研究

<正> 大多数梨的品种都存在着自交不亲和的现象,因此在栽培时,必须配置授粉品种。 半个世纪来,国内外学者对梨的授粉问题作了大量的研究,发现不同品种授粉对着果率及果实体积等性状有着不同的影响,互有差异,并对授粉品种的选配及果实的发育进行探索和研究。

STUDY ON SELECTION OF POLLENIZERS FOR 'HWANG HUA'PEAR

In 1983-1984, 'Hwang Hua' pear was cross-pollinated with ten pear cultivats. Flowering dates, fruit-set, fruit size, fruit weight, hardness, content of stone cells, and contents of sugar, organic acid, Vitamin C etc. were determined and compared. 'Xin Shi Ji' end 'Hang Qing' pears are the best varieties usedas pollenizer for' Hwang Hua' pear The result showed that the color, shape, quality, end other characters of pear fruit were not distinctly affected by pollenizers. But, different pollenizers for the'Hwang Hua' pear,can result in difference in the fruit weight. The fruit pollinated with 'Xin shi Ji', 'Hang Qing' and 'Hwang Mi' is obviously larger than with 'Ba Yun','Er Gong Bai',aud'Jing Bai'. The difference was about 50g.per-fruit.The fruit weight of Hwang Hua' pear was positively correlated with the fruit weight of pollenizers (r=0.7879～0.8114).
