叶面喷施5-氨基乙酰丙酸对甘蔗生长、产量和糖分的影响
Effects of Foliar Spraying 5-Aminolevulinic Acid on the Growth,Yield and Sugar Content of Sugarcane
摘要
Abstract
To further explore the effects of foliar spraying different concentrations of 5-aminolevulinic acid(5-ALA)on the growth indices,yield and sugar content of sugarcane,clarify the differences in the effects of different concentration treatments,this paper took the sugarcane variety Guitang55 as the experimental material.Treatment groups with foliar spraying of 5-ALA at concentrations of 100 mg/L(T1)and 50 mg/L(T2)were set up,and spraying with clear water was used as the control(CK).The plant height,stem diameter,and sugar content were measured 30 and 60 days after spraying,respectively,and the plot yield was measured during the harvest period and converted into the yield per hectare.After 30 and 60 days of spraying,the growth rates of plant height,stem diameter,and sugar content in the T1 and T2 groups were significantly higher than those in the CK.Among them,the T1 treatment had a more significant promoting effect on plant height and sugar content,while the T2 treatment had a more obvious effect on increasing the stem diameter.The yield of the T1 group increased by 34.57%compared with that of the CK,showing a significant yield-increasing effect.Therefore,foliar spraying of 5-ALA at a certain concentration can significantly improve the growth indices of sugarcane and thus increase the yield,and there are certain differences in the effects of different concentration treatments.This study provides theoretical support for the application of 5-ALA in sugarcane cultivation.However,the regulatory mechanism of 5-ALA on sugar metabolism in sugarcane,as well as its application effects on different varieties and at different growth stages,still need further research.关键词
