The early-maturing eddo "June Red" is a specific dasheen species with numerous cormels in Yongding county.

摘要“六月红”早熟芋是永定县特有的多子芋品种。

Studies were made on the vegetative propagation coefficient and cormel's biological characters using eighth-excision in different development phase of Lycoris radiate.

摘要在红花石蒜不同生长发育期进行八分法切割繁殖，研究无性繁殖系数和子球生物学性状差异性。

(2) all of biological characters, such as cormel's fresh weight, size, height, root length, roughness and root quantities, presented 1% significant difference.

(2)不同生长发育期无性繁殖的子球鲜质量、最大直径、子球高度、根系长度、根基粗度及根系数量等生物学性状均呈现1%水平极显著差异。
