野生东北百合生物量及主要营养元素的分配

Biomass and primary nutrient elements distribution of wild Lilium distichum

对野生东北百合(Lilium distichum)的生物量和N、P、K的分配进行了研究。结果表明,各生长期内,东北百合营养器官生物量分配比例较大,叶的生物量分配逐渐降低,生殖器官的生物量分配逐渐增加,生殖构件与叶呈显著负相关;生殖构件N、P、K的分配高于营养构件各元素的分配,营养构件中P的分配差异不大。

A study was conducted to evaluate the distribution of the biomass and N.P,K within wild Lili-um distichum. The results suggested that biomass distributions of L. distichum were different in different growth stages. The ratio of biomass was higher in nutrient organs than in reproductive organs, the ratio of biomass in leaves decreased gradually and the ratio of biomass in reproductive organs increased gradually. The ratio of biomass in reproductive organs had negative correlation with that in leaves. The ratios of N, P,K content in reproductive organs were higher than in nutrient organs. There was no difference between the distributions of P in nutrient organs.
