摘要:
通过对6月龄棚栽不同种源金线兰及近缘种的农艺性状、多糖和总黄酮含量的测定，结果表明：不同种源金线兰农艺性状间差异显著，对照种福建金线兰百株鲜重和百株干重均最高，分别达284.75、45.885 g；来源于广西百色的金线兰多糖含量最高，含量达169.61 mgg-1DW，比对照种增加36.56%；来源于福建省沙县南阳乡竹山村的金线兰（7号）总黄酮含量最高，含量达9.18 mgg-1DW，比对照种增加34.74%。台湾银线兰多糖含量低于金线兰和野生齿唇兰，总黄酮含量高于野生齿唇兰，并与对照种福建金线兰相当；来源于福建沙县南阳乡竹山村的金线兰叶脉无线种（7号）多糖和总黄酮含量均较高，具有较好的开发前景。
Abstract:
Major agronomical characteristics and contents of polysaccharides and flavonoids in Anoectochilus roxburghii and related species from different areas cultivated in a greenhouse for 6 months prior to the chemical analyses were compared. There were distinctive agronomical differences among the sampled species. For instance, the highest yield was shown CK from Fujian, with a per hundred plants fresh weight(FW) of 284.75 g and dry weight (DW) of 45.885 g; the highest polysaccharide content,in the variety from Baise, Guanxi, at 169.61 mgg-1DW, which was 36.56% higher than CK; and, the highest total flavonoids, in the cultivars from Zhushan Village, Nanyang Township, Shaxian, Fujian (No.7), at 9.18 mgg-1DW, which was 34.74% higher than CK.By comparison, the polysaccharide content of A. formosanus was lower than that of A.roxburghii and A. lanceolatus; the total flavonoids of A. formosanus, higher than that of A.lanceolatus, but not significantly different from those of the cultivars from Fujian; and, both polysaccharides and total flavonoid significantly higher in No. 7. Consequently, the cultivars from Zhushan was considered to have a potential for further study and promotion.
