冠菌素和茉莉酸甲酯处理对金银花矿质元素影响研究

Effects of COR and Me-JA on Mineral Elements in L.japonica

应用ICP-AES技术,测定并分析冠菌素和茉莉酸甲酯处理对金银花矿质元素含量、累积量和比例的影响。结果表明:(1)冠菌素处理使金银花K,Mg,Na,Zn,B,Si含量分别不同程度提高,P,Ca,Fe,Mn含量分别不同程度降低;(2)茉莉酸甲酯处理后金银花K,Na,Zn,B,Si含量分别不同程度增加,P,Ca,Mg,Fe,Mn含量分别不同程度降低;(3)冠菌素和茉莉酸甲酯处理后金银花K∶P和Na∶Zn升高,Ca∶Mg,Fe∶Mn,B∶Si降低。研究结果明确了冠菌素和茉莉酸甲酯处理对金银花矿质元素的影响,并为生长调节剂的合理使用提供科学依据。

ICP-AES technique was used to determine the content,accumulation and proportion of mineral elements in L.japonica and analyze the differences after treatment by COR and Me-JA.The results show that：（1） The content of K,Mg,Na,Zn,B and Si in L.japonica were increased by 5.82%,2.55%,155.17%,5.34%,16.11% and 142.15% respectively after treatment by COR,while the content of P,Ca,Fe and Mn was reduced by 3.99%,19.20%,38.89% and 35.96%（2） After treatment by Me-JA,the content of K,Na,Zn,B,and Si were increased by 4.46%,137.93%,6.09%,10.09% and 89.24%,however the content of P,Ca,Mg,Fe and Mn were decreased by 9.82%,20.29%,8.49%,42.00% and 36.80% respectively.（3） When treated by COR and Me-JA,K∶P and Na∶Zn were increased,while Ca∶Mg and Fe∶Mn and B∶Si were decreased.The results of this study define the influence of COR and Me-JA on the mineral elements of L.japonica,and provide a scientific basis for the rational use of plant growth regulators as well.
