Growth Characteristics and Yield of Anoectochilus roxburghii Cultivars

摘要: 以福建金线莲组培苗为试材，研究不同品种组培苗的生长性状差异和200 d栽培苗的生长性状、生长量和干物质含量的差异。结果表明：3个品种组培苗中，红霞和圆叶的外观特征和茎粗度均优于尖叶；3个品种200 d栽培期植株中，红霞的外观特征特别突出，单位面积鲜重产量和干物质产量均最高，红霞的综合表现第一，圆叶的综合表现第二，尖叶的综合表现第三。

Abstract: The in vitro growth characteristics of tissue cultured plantlets and the growth, biomass increase and dry matter content of 200-day-old seedlings of three varieties of Anoectochilus roxburghii were compared. The appearance and stem girth of the in vitro Hongxia and Yuanye plantlets were superior to those of Jianye. Among the 200-day-old seedlings, Hongxia had an outstanding appearance and the largest fresh weight yield and dry matters per unit area among the 3 cultivars. Overall, Hongxia was rated most desirable, followed by Yuanye and Jianye, for scaleup cultivation.
