摘要

本研究探討室內光強度20－100 lux、1000－2000 lux及4000－8000 lux對盆栽麗格秋海棠觀賞品質之影響。盆栽麗格秋海棠在觀賞期間置於20－100 lux低光度之室內，花苞無法開花，在光強度1000－2000 lux及4000－8000 lux之室內，花苞可順利開放，單花壽命分別為22.8天及27天；放置四週後，開花數以高光度區4000－8000 lux 27朵／盆最高，中光度區1000－2000 lux 11朵／盆次之，低光度區20－100 lux 3朵／盆最少；盆栽開花期高光度區可達八週，中光區約六週，低光區僅三週。

An experiment was conducted to study the effect of the indoor light intensity on longevity and quality of pot Rieger begonia. Potted plants were given 20-100, 1000-2000 and 4000-8000 lux in the indoor house for 12 weeks. Non-flowering response was observed in the treatment of lower light intensity at 20-100 lux, while the flowering buds easily bloomed when given 12 weeks of supplemental light at 4000-8000 lux and 1000-2000 lux, and the average longevity of single flower was 27 days and 22.8 days respectively. Supplementary lighting not only increased longevity but also increased flowering number. Lighting treatment of 4000-8000 lux obtained 27 flowers per pot, 11 and 3 flowers per pot for 1000-2000 lux and 20-100 lux treatment, respectively, whereas the longevity of pot plants for 4000-8000 lux were 8 weeks and were 6 weeks for 1000-2000 lux, were only 3 weeks for 20-100 lux.
