摘要

本研究目的在於探討不同介質與育苗盤對紫錐花幼苗品質之影響。試驗結果顯示，比較第五週齡幼苗之地上部、地下部的鮮重及乾重，均以本場調配之介質（TC1）配合60格穴盤最高，鮮重分別為1.31 g及1.569 g；乾重分別為0.169 g及0.199 g。表現較差的為市售之泥炭苔配合水稻育苗盤且達顯著性差異。在品質分析方面，利用不同品質分析方法A及B，由評估壯苗品質指數顯示，以本場調配之介質配合60格穴盤表現最好，而市售之泥炭苔配合水稻育苗盤表現最差。在養分含量方面，使用本場調配之介質之幼苗地上部磷、鉀及鎂含量顯著高於市售之泥炭苔處理。

The objective of this study was to assess the effects of various media and trays on the seedlings quality of purple coneflower. These results indicated that the seedling weight in 5 week-age cultured in 60-cell plug tray with Taichung DAIS No 1. medium (M0T1) had positive effect. The fresh weight and dry weight of shoot and root were 1.31 g, 1.569 g, 0.169 g and 0.199 g, respectively, so that the seedling quality was better than that planted in rice tray (M1T0) with peat moss medium. The index of seedling quality A and B were used to evaluate the quality of purple coneflower seedlings in different media and trays. Seedlings planted in 60-cell plug tray with Taichung DAIS No 1. medium (M0T1) had best performance than that in rice tray (M1T0) with peat moss medium. However, the uptakes ability of P, K and Mg of seedling nutrient of purple coneflower in all trays with Taichung DAIS No 1. medium (M0T1) were better than that in the other trays with peat moss medium at 5 weeks after sowing.
