4种植物生长调节剂对台农芒果控梢效果及开花的影响

Effects of 4 Plant Growth Regulators on Controlling Shoot and Flowering of Parthenon Mango

本文选用4种植物生长调节剂(氟节胺、调环酸钙、烯效唑、多效唑)探究对台农芒果的控梢效果,以及对后期抽花率及花穗长度的影响。结果表明,芒果控梢中期进行用药,氟节胺、调环酸钙、烯效唑+调环酸钙、多效唑处理可显著降低新梢长度,多效唑、烯效唑+调环酸钙、调环酸钙有良好的脱叶和去除嫩芽的效果;此外,药剂处理控梢效果越好,花穗长度越短。

In this article,four plant growth regulators(flumetralin,prohexadione calcium,uniconazole and paclobutrazol)were used to study their effects on controlling shoot,as well as the effects on the later extraction rate and spica length of Parthenon mango.The results showed that when the growth regulators were spraying at middle stage of shoot control,the length of mango new shoots could be significantly reduced by the treatment of flumetralin,prohexadione calcium,uniconazole+prohexadione calcium and paclobutrazol;while prohexadione calcium,uniconazole+prohexadione calcium and paclobutrazol had good defoliation and bud removal effect.In addition,the better the effect of agent treatments,the shorter the length of the spica.
