Comparision of Growth and Quality of Anoectochilus roxburghii from different regions

Through the research on difference of growth and quality parameters of Anoectochilus roxburghii plantlets from Fujian province, Yunnan province, Taiwan province and Brazil. The result showed that the growth source quality in the order of Taiwan province>Fujian province>Brazil>Yunnan province;The polysaccharide content of A. roxburghii in the order of Fujian province (Taiwan province)>Brazil>Yunnan province; The total flavonoids content of A. roxburghii in the order of Fujian province > Yunnan province (taiwan province) > Brazil; The total alkaloid content in the order of Yunnan province (Brazil) > Fujian province>taiwan province;the total amino acid content in the order of Yunnan province>Brazil (taiwan province)>Fujian province. The yield is significantly positive correlated to stem diameter and leaf numbers;There is a significant negative correlation between the total alkaloid content and stem diameter; Moreover, there is a highly significant negative correlation between the total alkaloid content and leaf numbers.
