摘　　要：以湿栽水芹D07为试验材料，研究了种子繁殖过程中不同分苗苗龄对湿栽水芹生长、根系活力、品质及功能性成分含量的影响。结果表明：2～3片真叶期为湿栽水芹种子繁殖的适宜分苗苗龄，可以培育出长势一致的优质苗，叶柄长、叶柄粗、植株鲜质量等生长指标及根系活力、壮苗指数均为最高，品质较好，功能性成分含量也较高；而子叶期分苗的育苗效果较差。Taking seeds of wettish-cultivated water dropwort〔Oenanthe stolonifera（Roxb）Wall.〕‘D07’as experimental material,studied the effect of different reculturing seedling ages on the growth, functional components of root system and leaf blades. The results indicated that the 2-3 true leaf stage is proper age for reculturing seedling,which could culture superior seedling with uniform growth.The petiole length,petiole width,plant fresh weight,etc.,and growth index,root system activity,strong seedling index were the highest. Its quality was better,and functional component contents were also high.While cotyledon stage treatment would make the reculturing seedling to have poor culture effect.
