不同生长调节剂对果蔗产量和品质的影响

The Effect of Different Growth Regulators to the Quality and Yield of Garden-cane

试验结果表明:植物生长调节剂喜田宝对果蔗分蘖增加、植株长高、茎径增大、蔗汁抽出率提高等具有正效应;赤霉素对分蘖、茎径等有轻微负效应,但对植株增高、有效茎增多则有显著正效应;植物龙对农艺性状和产量性状均为负效应,但却能显著提高蔗糖分。

The results of the experiment showed that Xitianbao (a growth regulator) had positive effects to tillering, plant height, diameter, juice extraction ratio etc of garden cane. Gibberellin had slight negative effects to tillering and diameter et al but it had positive effects to plant height and available stalks. Zhiwulong had negative effects to the characters of agronomic and yield but it can markedly increase sucrose content.
