摘　　要：为合理利用百合种质资源,采用引种栽培、大田调查的方法,对百合生育期和形态特征进行观测.结果表明,不同产地引种的百合出苗期、现蕾期、花期和生长量变化均不相同,湖南省隆回县的龙牙百合出苗最早;衡山县的野生百合现蕾最早;卷丹花期可延续至8月中旬.百合生长有2种类型:一种是前期快速生长,现蕾后生长减慢,或趋于停止;另一种是开花前后一直缓慢生长.卷丹和百合种间差异较大,但百合种内、卷丹种内差异较小,且比较稳定,说明种质间的变异大于种质内的变异.To make good use of germplasm resources of specicy lily reproductive period and the morphological characteristics were observed through choosing suitable cultivars and using field investigation methods. The results show that ： The seeding stage, squaring period, florescence and the variety of growth among the lily＇s germplasm which were introduced from different places were different. Lilium. brownii F.E.Brown＇s sprout which was introduced from Longhui county（Longya） came the earliest. L. brownii F.E.Brown introduced in the wild from Hengshan county showed flower bud first. The florescence ofL. lancifolium Thunb lasted till the middle of August. There are two different growth curves： the one indicated rapid growth in the earlier stage, the speed of growth slowed down after flower bud, or tends to have a stoppage; the other suggested low growth speed around period of bloom. The difference between L. brownii F.E.Brown and L. lancifolium Thunb. was remarkable, but the difference among different L. brownii F.E.Brown or different L. lancifolium Thunb. was small and atable, indicating variation between that the species was greater than intraspecifie variation.
