不同催花时期对菠萝果实生长发育的影响 Effects of Different Forcing Date on Growth of Pineapple Fruit

以巴厘品种作为试验材料，选择3个不同的催花时间，分析不同催花时期对菠萝果实生长发育及可溶性糖含量的影响。在距离催花相同的时间测定果实各指标，结果表明，9月9日催花的菠萝冠芽高、果长、果径低于其它催花处理。9月9日催花的菠萝果实可溶性总糖含量显著高于其它催花处理。 The differences of pineapple fruit growth and total soluble sugar were studied in three different forcing times with pineapple Ananas comosusr cv. Yellow Mauritius. The results showed that the crown height, fruit length and fruit diameter of pineapple forced on 9th September were lower than the other forcing date at the same time after forcing. However, the content of total soluble sugar in fruits forced on 9th September was significantly higher than the other forcing date treatments.
