云南茶树良种氟含量变化比较研究
Comparative Study of Improved Tea Varieties on Fluoride Content Change in Yunnan
摘要
Abstract
[Objective] The aim was to know the fluoride accumulation characteristics of different tea varieties,and provide a scientific basis for selecting large leaf tea varieties with low fluoride accumulation.[Method] The fluoride content was determined by the Method of Fluoride-ion Specific Electrode in four leaves one bud of twenty tea varieties collected from tea varieties garden of Menghai,Changning and Simao in Yunnan province.[Result] The results showed that the average content of fluoride of the varieties was 15.30-157.60 mg/kg mg/kg in these areas.The average content of fluoride of Yunkang 10 was the lowest in seven tea varieties in Menghai,Changning and Simao as a whole.The LSD multiple comparison results showed that the average content of fluoride was a certain difference among the varieties in the same area and among the areas in the same variety.The average content difference of fluoride of Yunkang 10 was very no significance among seven tea varieties of Menghai and Changning except Simao.[Conclusion] Yunkang 10 can be used as control variety with researching fluoride accumulation of large leaf tea and selecting low fluorine material in Yunnan.关键词
