影响芒果叶中芒果苷含量的生长因素研究

目的探讨芒果树生长过程中，影响芒果苷在芒果叶中累积的各种因素。方法通过控制光照、水分、施肥、挂果量、不同良种交互嫁接等生长因素，达到影响芒果叶生长的目的，然后采集芒果叶样品，测定其中的芒果苷含量。结果挂果量、不同良种的交互嫁接不影响芒果叶中芒果苷的含量；减少水分供应、提高光照时间和强度，能提高芒果叶中芒果苷的含量；过多的施水或施用富氮肥料可明显降低芒果叶中芒果苷的含量。结论提高光照时间和强度、降低芒果叶的生长速度，能显著提高芒果叶中芒果苷的含量；挂果量和不同良种交互嫁接对芒果叶中的芒果苷含量没有影响。

Study on the Factors Affecting the Mangiferin Contents in Mango Leaves

Objective To study the growth factors which affect the mangiferin contents in Mango Leaves. Methods Mango trees cultivated by controlling growth factors such as illumination , water, fertilizer, fructification and graft. Then Mango leaves were tested to determine the mangiferin contents. Results Graft and fructification didnt affect the mangiferin contents in Mango leaves ; less water and/or more illumination made higher Mangiferin contents ; but if more water and/or nitrogenous fertilizer mere applied, the mangiferin contents became less. Conclusion More illumination and/or low growth rate make Mango leaves have higher Mangiferin contents, while graft and fructification make no difference .
