中文摘要 | 商用雜交百合為我國首要的高價球根花卉產業,幾乎遍植於臺灣地區各地。百合 植株生長明顯受到氣候環境的影響,為了維護切花品質、預測開花日期、及栽培種球,必須 充分瞭解百合與氣象之間的關係,方得據以調整栽植期及改進栽培措施。本文研究旨在探討 氣象因子對百合株高、地上部乾物重、及開花期之效應,因此選用常見的亞洲型與東方型百 合四品種參試。試區設於臺中縣霧峰鄉臺灣省農業試驗所農場,試驗栽植日期自1995年三 月至1996年三月止計九次植期,並以農試所內一級農業氣象測站測值做為分析之氣象資料。 根據試驗結果,百合株高與生育期間累積日射量呈顯著相關,在收穫前株高隨著日射量的累 積而上升。地上部乾物重表現趨勢類似於株高曲線,亦可由一元二次曲線方程式表示。開花 期則與生育全期平均氣溫、累積日射量、及累積日照時數呈現直線相關,平均氣溫愈高開花 期愈長,東方型百合品種又較亞洲型百合品種需要較長日數。以累積日射量及累積日照時數 而言,東方型百合均需要較高數值以達到開花。由逐步回歸分析發現,影響各品種開花期的 主要氣象因子並不一致,各有特色。綜合試驗結果本文據此建議,為避免惡劣氣象環境不利 於雜交百合生長與開花,臺灣中部地區的栽植期宜避開四月至八月。 |
英文摘要 | Commercial hybrid lilies are commonly planted over a wide range of climate in Taiwan. The actual growth varies from conditions of local climate which is a much more important consideration in flower production. This research studied climatic effects on plant height, aboveground dry weight, and days to flowering of two Asiatic and two Oriental hybrid lilies in the experimental farm of Taiwan Agricultural Research Institute (TARI), Taichung during 1995-1996. The weather data were collected from weather station located at TARI. It was shown that plant height was significantly correlated with the accumulated irradiance, but not others, of the growing season. Although with different sowing dates, plant elongation was gradually increased as solar radiation accumulated. Patterns of aboveground dry weight were quite similar to that of plant height and were also significant in second order regression equations. For all cultivars, time from sowing to flowering had linear relationships with the average temperature, cumulative irradiance, and cumulative sunshine hour of the growing periods. A negative correlation was found with the average temperature of the growing period, time to flowering decreased as the average temperature increased and Oriental hybrid lilies needed more time to reach flowering than those of Asiatic lilies. On the other hand, Oriental hybrids needed more cumulative irradiance and sunshine hour to anthesis than those of Asiaic ones. By stepwise regression analyese, results showed that each cultivar has different climatic factors as prevailing element(s). To minimize the risk of climatic hazard in growing hybrid lilies in the central part of Taiwan, it is not recommended to plant these hybrid lilies from April to August. |
