摘　　要：收集了11省(市)23县(市)的23个鱼腥草种质资源,在浙江省丽水市林业科学研究所百果园基地进行种源特性观察试验,结果表明,23个种源从形态特征上可分为二大类,一类为生长初期叶绿色,茎节间较长,生长盛期叶翠绿色,叶缘波状,茎浅红色;另一类为生长初期叶带紫红色,茎节间较短,生长盛期叶墨绿色,叶近全缘,茎紫红色、浅红色或绿色。物候期较为一致,可分为破土萌芽长叶期(2月下旬到3月下旬)、快速高生长期(3月底到4月中旬)、开花结果期(4月下旬到6月底)3个阶段。不同鱼腥草种源在高、径生长和蒴果、种子数量等方面均存在显著差异。高生长以18号(浙江嵊州)种源最好,平均高度达83.08 cm,15号(安徽绩溪)种源最低,仅为41.08 cm;径生长以4号(云南会泽)种源最好(0.506 3 cm),15号(安徽绩溪)种源最差(0.3 cm)。综合性状以4、18、19(浙江长兴)、12(浙江嘉善)、5(贵州安顺)、17(浙江泰顺)等种源表现较好,能获得较高的生物量。单果序蒴果数以7号种源(河南正阳)最多,达83.4颗/果序,蒴果内种子数以10号种源(广西柳州)最高(22.67粒/蒴果),综合蒴果和种子数量以10、5号种源较好。Twenty three provenances of 22 counties of 11 provinces of Houttuyniae cordata were collected and were planted in Baiguoyuan of Lishui, Zhejiang province to study their properties. The results indicated that 23 provenances could be divided into 2 types according to their morphology characters. One type had green leaf at intial growth stage, long interajoint pink stem, Paris green leaf at peak of growing season, wave leaf costa, while another type had purple-red leaf at infial stage, short interajoint pink, purple-red or green stem, jasper leaf at peak of growing season, full leaf costa. Their phenological periods were similar and could be divided into 3 stages： germination from the last ten-day of February to the last ten-day of March, fast heigh growth from the end of March to the middle ten-day of April, flowering and fruit bearing from the end April to the end of June. There were significante differences among provenances on height and diameter growth, amount of fruit capsule and seed. Provenance of No 18 （Shengzhou, Zhejiang） had the best height growth with mean of 83.08 cm, the lowest was No 15 （41.08cm, Jixi, Anhui）. Provenance of No 4（Huize, Yunnan） had the best diameter growth with mean of 0.5063cm and the last was No 15 （0.3cm）. Provenance of No 7 bad the most amount of fruit capsule, the lowest was No.17. Provenance of No.10 had the most seed with 22.67/capsule.
