Abstract
The characteristics of seasonal change of dry matter allocation to component organs among juvenile (J), small size bolting (B1) and later stages individual of Lilium auratum Lindley were studied under the condition of cultivation. The threshold fresh weight of underground parts value of the transition from J to B1 stage was estimated approximately 0.666g. The B1 allocated higher proportion of dry matter for productive parts than J, which caused more 8 days required to recover weight in dormant period. The seasonal change of dry matter showed the presence of enough light environment from sprouting period to end of May in forest floor was required for maintaining Lilium auratum Lindley populations.
