Abstract
本研究係於臺灣省農業試驗所農場進行田間試驗，以兩類不同雜交型的百合-亞 洲型和東方型為試材，選擇進口百合適宜生長的月份(九至翌年三月)種植寸匕較不同栽植 月份百合營養生長、生殖生長及地下部子鱗莖消長之差異，並輔以性狀模式化分析，藉以 評估栽植期效應對不同類型的進口百合的生育影響。試驗結果顯示，隨著定植週數的增加 ，植株高度、葉片數、葉面積及地上部植株乾重亦隨之增加，至開花時期達到高峰。生長 曲線大多可以一元二次方程式表示，除地上部植株乾重無下降趨勢外，其它生長性狀皆略 為減少。不同栽植月份的營養生長表現以9-12月較1-3月佳，而以'Pollyanna'雜交種在不 同栽植月份的生長差異較大。百合鱗莖經定植後，其周徑和重量皆因生長所需而減少，在 開花期後則緩慢增加，此鱗莖周徑和重量增減之曲線以亞洲型百合較為顯著。百合開花特 性因不同栽植月份產生差異，大致而言以接近冬季定植的月份(10至12月)，其開花期較長 、花朵數較多、單朵或全株的開花日數較長，且亞洲型百合花朵品質之優劣程度較東方型 明顯，顯示其受生長環境的影響較大。
It is well known that growth performance of a crop is governed by its environment, and maximum yield can hardly be attained to genetic potential owing to stress conditions encountered during growing frame. Field experiments were conducted at Taiwan Agricultural Research Institute Experimental Farm to evaluate planting date effect on plant growth, flowering and daughter-bulb formation of Asiatic and Oriental types hybrid lilies. Changes of characters of plant, flower and bulb were also modeled to analyze temporal variations. It showed that growth curves of plant height, leaf number, leaf area and aboveground dry weight were curvilinear and reached their peak at about flowering stage. Plants grew better when planted from September to December in 1995 than from January to March in 1996. Circumference and weight of bulbs were decreased after planting and gradually regained their size since flowering, especially for the Asiatic type lilies. Size of daughter bulbs of Asiatic hybrids, but not Oriental lilies, was larger than the planted bulbs. In the flowering characters, days to flowering and flowering duration were longer and more flowers were produced for those planted from October to December. Such variations were pronounced in Asiatic lilies than in Oriental ones, implying the existence of varietal differences of sensitivity to planting environment.
