目的:评价甘蔗叶不同生长期多糖含量变化的动态积累。方法:以苯酚-硫酸法测定不同生长期甘蔗叶中多糖的含量。结果:甘蔗叶中多糖的含量呈规律性变化,在甘蔗光合作用旺盛的8~9月份采收时多糖的含量较高。结论:该文结果可为甘蔗废弃部分甘蔗叶的有效利用提供科学依据。
Objective: To evaluate the dynamic accumulation of polysaccharide in different growth stages of sugarcane leaves. Methods: The contents of polysaccharides in sugarcane leaves at different growth stages were determined by phenol - sulfuric acid method. Results: The contents of polysaccharides in sugarcane leaves changed regularly, and the content of polysaccharides in harvested sugarcane was high from August to September. Conclusion: The results of this paper can provide a scientific basis for the effective utilization of sugarcane sugarcane leaves.
