不同浓度赤霉素对果蔗产量和品质的影响试验总结

The Effects of Different Concentration of Gibberellin on the Quality and Yield of Garden Cane

试验结果表明:浓度为1:15000的赤霉素药液对果蔗的多数农艺性状、全部产量性状、多数商品性状、工艺性状及抗螟性等均有正效应,对果蔗的少数农艺性状、商品性状和抗病性等有轻微负效应,是本试验中对果蔗效果最佳的浓度;浓度为1:5000的赤霉素药液对果蔗产量性状、工艺性状具有显著正效应,对果蔗农艺性状、少数工艺性状、抗螟性等具有明显正效应,对少数商品性状、极少数工艺性状有轻微负效应,是本试验中对果蔗效果位居第2的浓度;浓度为1:7500的赤霉素药液对果蔗农艺性状、产量性状、多数商品性状和抗螟性等具有正效应,对少数产量性状、商品性状和个别工艺性状具有负效应,是本试验中对果蔗效果位居第3的浓度。

The result of the experiment showed that Gibberellin liquid of 1：15000 had positive effects on most agronomic characters, all yield characters, most commercial characters and borer resistance etc., but it had slightly negative effects to a few agronomic, commercial characters and diseaseresistance etc, It is considered the optimum concentration. Gibberellin liquid of 1：5000 was secondary in effect on the quality and yield of garden cane in the test, and Gibberellin concentration of 1：7500 performed third.
