| 摘 要： | 以2年生青钱柳(Cyclocarya paliurus)幼苗为材料,通过叶面喷施不同质量浓度的水杨酸、纳米TiO2、稀土硝酸镧、硝普钠溶液,研究其对青钱柳幼苗叶片黄酮和微量元素含量的影响。调控结果表明:水杨酸(200 mg/L)处理对青钱柳叶片中山萘酚、异槲皮苷含量提高效果最佳,分别达到21.199、0.413 mg/g;而对槲皮素含量的影响最大的是100 mg/L的水杨酸处理,含量可达到6.507 mg/g;400 mg/L纳米TiO2处理对微量元素Fe含量影响最大,Fe含量可达到1.375 mg/g。

| Abstract: | The effects of exogenous substances on contents of flavoniods and trace elements in Cyclocarya paliurus leaves of 2-year-old seedlings were investigated by spraying different concentrations of salicylic acid(SA),nanometer titanium dioxide(Nano-TiO2),lanthanum nitrate(LN) and sodium nitroprusside(SNP),respectively.The results showed that 200 mg/L SA has the best effect on increasing the content of isoquercetin and kaempferol in the leaves,and the contents of isoquercetin and kaempferol were 21.199 mg/g and 0.413 mg/g.However,the greatest content of quercetin achieved in the 100 mg/L SA treatment,which was 6.507 mg/g.The highest contents of inorganic ions Fe was obtained in the 400 mg/L Nano-TiO2 treatment,which was 1.375 mg/g. |
