　　 本研究目的在於探討不同介質與育苗盤對紫錐花種子出土率及幼苗生長之影響。試驗結果顯示，紫錐花出土率在播種後第四週已逐漸穩定，已達 32.8~44.1% ，其中以本場調配介質 (TC1) 配合 60 格穴盤之出土率 44.1% 較佳，以市售之泥炭苔配合 128 格穴盤的 32.8% 出土率顯著最低，其中本場調配介質之各式育苗盤均較泥炭苔介質處理為佳。在第五週齡苗不論在株高、植株展幅、葉數、葉長、葉面積、地上部及地下部乾重方面均以本場調配之介質 (TC1) 配合 60 格穴盤最高，分別為 3.25 cm 、 5.13 cm 、 3.25 片、 4.45 cm 、 9.93 cm² 、 0.199 g 及 0.369 g ，表現較差的為市售之泥炭苔配合 128 格穴盤與泥炭苔配合水稻育苗盤 (M₁T₀) 且達顯著性差異。 關鍵字： 紫錐花、介質、育苗盤、出土率 。

　　 The objective of this study was to assess the effects of various media and trays on seed emergence rates and seedling growth of purple coneflower. The results indicated that the stable seeds emergence rates of purple coneflower were 32.8-44.1% at 4 weeks after sowing. The highest of rates of seed emergence in 44.1% were found in 60-cell plug tray using Taichung DAIS No. 1. medium (M0T1) and the lowest rate in 32.8% was found in 128-cell plug tray using peat moss medium (M1T2). Significant differences of emergence rates between two media were found in all trays.

　　The horticultural characteristics such as plant height, plant width, number of leaves, leaf length as well as dry weight of shoot and root of seedlings, cultured in 60-cell plug trays with M0T1 medium were 3.25 cm, 5.13 cm, 3.25 leaves, 4.45 cm, 9.93 cm2, 0.199 g and 0.369 g, respectively. However, 60-cell plug tray with M0T1 medium was the best treatment, which was significantly better than that planted in 128-cell (M1T2) and rice tray (M1T0) with peat moss medium.

Key words: Echinacea purpurea (purple coneflower), medium, tray, emergence.
