摘要
以金花梨、早酥梨、线穗梨、金秋梨四个大果型梨品种为试材 ,在不同时期 ,采用不同距离疏花 ,研究了它们的果实早期发育的特点。结果表明 :早期疏花幼果细胞数增多 ;果实体积与细胞数、细胞大小呈正相关。疏花时期与疏花距离的最佳组合为 :花序分离期 ,间距 2 5～ 30 cm。
The effect of flower thinning in different periods and with different distances to the earlier fruit development of the four pear varieties was studied. Results showed that the earlier flower thinning can increase the number of the cells of young fruits,the more cells there are in the fruit and the larger cell volume is, the larger fruit volume is.The most proper combination between the period and the distance of flower thinning is selected.
