| 摘 要： | 通过2年2点对4个不同矮蔓型西葫芦品种商品瓜位置与化瓜等指标进行了研究,结果表明,不同矮蔓型西葫芦品种商品瓜离生长点的距离不同,结果中期半矮蔓品种平均为20.9cm,矮蔓品种为14.9cm,这主要是由于节间长度不同引起。不同矮蔓型西葫芦品种的化瓜率都较高,达37.9%~40.3%,品种间差异不显著,半矮蔓品种化瓜主要在商品瓜下方,矮蔓品种主要在商品瓜上方;生育后期商品瓜位置与新生叶的产生正相关,半矮蔓品种商品瓜对新生叶产生抑制作用小,库之间的竞争是其化瓜的主要原因,矮蔓品种商品瓜对新生叶产生抑制作用大,源的供应不足是其化瓜的主要原因。建议在生产中通过控制节间长度调节营养生长与生殖生长的平衡。 |

| Abstract: | Fruit abortion in relation to fruit set position was investigated using 4 different type bush summer squash varieties in 2 years and 2 locations. The results showed that marketable fruits were produced from different height on different variety due to the length of internode,20.9 cm for semi-bush varieties and 14.9 cm for bush varieties. During early stage the fruit abortion rates were 37.9%-40.3% and no significant varietal differences were observed. During late stage, fruit development had less inhibits to the development of new leaves and the fruit abortion was because of the competition among fruits in semi- bush varieties. However, fruit development inhibited the development of new leave and the fruit abortion was mainly due to short supply of source in bush varieties. We recommend achieving the balance of vegetative and reproductive growth by regu- lating internode length. |
