福建金线莲不同品种生长性状和产量比较

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.%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 .
