摘要

本研究旨在探討環控室內不同光質處理對苦瓜育苗品質之影響。試驗結果顯示，光量維持在150 μmol m^(-2) s^(-1) 的情形下，以RGB(51:24:25)處理最佳，株高、莖粗、葉片數、根長、地上部鮮重、地下部鮮重、地上部乾重、地下部乾重、全株乾重及壯苗指數分別為23.42 cm、3.07 mm、8.83 片、29.75 cm、4.51 g、3.82 g、0.85 g、0.29 g、1.14 g 及1.34。本研究證實在環控室內以人工光源取代太陽光進行苦瓜育苗是可行的。

This study was intended to explore the effects of light quality on the seedling quality for bitter gourds at a controlled environment room. Experimental results showed the seedling quality of RGB (51:24:25) treatment was the best at 150 μmol m^(-2) s^(-1) light intensity, and plant height, stem diameter, number of leaf, root length, fresh weight of shoot, fresh weight of root, dry weight of shoot, dry weight of root, dry weight of plant, seedling index were 23.42 cm、3.07 mm、8.83 leaves、29.75 cm、4.51g、3.82 g、0.85 g、 0.29 g、1.14 g and 1.34, respectively. This study confirmed the environmental control room by using the artificial light source to replace the natural sunlight for bitter gourds seedling production was feasible.
