摘要

本試驗乃探討亞洲型百合Asterix、Cardillac、Festival、Florence及Promine-nce等5品種之鱗莖，經5℃冷藏3至6週後種植，對於植株生育、抽莖、開花及後代子球品質之影響。結果顯示；品種間對於低溫需求程度不同，Cardillac、Prominence及Asterix對低溫為短需求性之早生性品種，冷藏3週便足以使80%以上之鱗莖萌芽；冷藏6週則100%均可萌芽且抽莖，定植後分別於92、88、87天即可開花。而Festival及Florence對低溫為長需求性之晚生性品種，冷藏6週仍不足以使全部的植株抽莖，定植後分別需120及147天才能開花。亞洲型百合開花期受冷藏時間長短之影響，冷藏時間愈長則從定植到開花之日數愈短，但縮短效果到處理第5週似已達頂點。不同冷藏週數對於植株高度、單株花朵數及子球品質等性狀的影響，則差異並不明顯，除了各品種固有特性外，應與當時栽培的氣候環境有關係。

To compare the effect of cold storage on plant growth, shoot emergence, flowering, and bulb quality of asiatic hybrid lilies, 5 cultivars 'Asterix', 'Cardillac', ”Festival', 'Florence', and 'Prominence' were investigated. The bulbs were stored in 5℃ for 3 to 6 weeks, then planted into field. It showed that cultivars had different chilling requirement. Asterix, Cardillac, and Prominence were early cultivars with low requirement. More than 80% of the bulbs of those cultivars sprouted in 3 week treatment. In 6 week treatment, 100% of the bulbs were induced to sprout, emerge, and anthesis at 87, 92 and 88 days, respectively, after transplanted. For late cultivars Festival and Florence with long chilling requirement, 6 week treatment was still not enough to incduce shoot emergence. Flowering of Festival and Florence started at 120 and 147 days, respectively, after bulbs transplanted. The amount of days from planting to flowering of asiatic lilies shortened as the duration of cold storage increased from 3 weeks to 5 weeks. This shorten effect seems to reach the highest at 5 weeks treatment. The duration of cold storage did not significantly affect plant height, flower number per plant, and quality of daughter bulbs. It seems that those characteristics were not only affected by genotype but also related to the climate during cultivation.
