摘要: 有斑渥丹(Lilium concolor Salisb. var. pulchellum(Fisch.)Regel)每蒴果含成熟种子33~208粒,种子千粒重3.5g,发芽率(65.0±3.8)%,种子寿命2年。在试验圃地中, 2年实生植株开始开花,每株一朵,开花率56.6%,花部畸形严重,畸形率66.7%,其中花冠畸形率16.7%,雌蕊退化率20.0%,结实率20.0%,每果平均含成熟种子75粒;三年实生植株全部开花,每株1~3朵,花冠正常,雌蕊退化率35.1%,结实率62.1%,每果平均含成熟种子107.3粒。有斑渥丹花部变异,特别是雌蕊退化,可能是在栽培条件下的一种有利于种群延续的适应。

Abstract: One capsula of Lilium concolor salisb. var. pulchellum (Fisch.) Regel contains 33 to 208 seeds whose weight per 1000 seeds is 3.5g, germintion rate (66.0±3.8)% and longivity 2 years. Plant initiates to differentiate one flower in 2 years old in seedling nursery. And flowering rate of the lily is 56.6% but flowers are serious malformation. The 66.7% of malformation rate, which includes 16.7% of corolla malformation and 20% of gynecium malformation, results in 20.0% of fecandity. The average number of mature seeds per capsula is 75 seeds. All plants can differentiate 1 to 3 flowers whose corolla is normal and malformation rate of gynecium 35.1% in 3-years old. While the fertility rate of the lily is 62.1%. The reason of flower malformation, especially gynecium malformation, may be an adaptation favouring the continuance of the population under cultural conditior.
