Time of flower bud differentiation in 18 lily species native to Japan was surveyed and classified into 4 groups as follow: Type 1-a. l.rubellum and L.dauricum. Flower bud was initiated in early fall and was completed in early winter within bulb before sprouting. Type 1-b. l.concolor var.pulchellum(Chosenhimeyuri),L.japonicum, L.maclatum(native to Sadoga-shima), and L.hansonii. Flower bad was initiated in late fall within bulb before sprouting and was completed in next spring when the plant sprouted from the ground.Type 2-a. L.longiflorum, L.alexandrae, L.nobillissimum, L.speciosum, L.auratum, L.platyphyllum, L. leichtlinii var. maximowiczii, L.medeoloides, L.callosum, L.brownii, L.concolor(Tosahimeyuri), L.maculatum(native to Miyake-jima). Flower bud was initiated just after sprouting.Type 2-b. L.lancifolium and L.hanryi. Flower bud was initiated about one month after sprouting. Time of flower bud differentiation in 84 cultivars belong to Asiatic hybrid was surveyed and classified into 4 groups as lilies native to Japan.

对日本18种百合的花芽分化时间进行了调查，并将其分为4类：1-a型;红毛忍冬（L.rubellum）和蝙蝠葛（L. dauricum）。花芽在初秋萌发，初冬在鳞茎内完成，然后萌发。1-B型。美丽同色乳杆菌（Chosenhimeyuri）、日本乳杆菌（L.japonicum）、斑点乳杆菌（L.maclatum）（原产于Sadoga-shima）和汉森乳杆菌（L. hansonii）。落花发生在晚秋鳞茎内萌芽前，次年春天植株破土而出时落花完成。L.longiflorum、L. alexandum、L. nobilissimum、L.speciosum、L.auratum、L.platyphyllum、L.莱希特利尼变种maximowiczii、L.medeoloides、L.callosum、L.brownii、L.concolor（Tosahimeyuri）、L.maculatum（原产于Miyake-jima）。花芽在萌发后即开始形成，2-B型。卷叶草和汉氏卷叶草花芽萌发后一个月左右开始萌发。对84个亚洲百合品种的花芽分化时间进行了调查，并将其分为4类。
