染色效率与原植体类型和细胞密度有关。
形成藻殖段是发菜原植体繁殖的主要方式。
Forming hormogonium is a main reproductive way of Nostoc flagelliforme by thallus.
水生原植体的光合固碳能力比天然原植体高。
The aquatic-living colonies had a higher photosynthetic carbon fixation capacity than the natural colonies.
原植体为丝状或片状，大小不一，小的仅数个细胞，大的形态复杂如树状。
Composed of filaments or plates of cells, a thallus ranges in size from a single-celled structure to a complex treelike form.
藻体呈丝状，分枝多，常交织形成天鹅绒般的假原植体，长达30公分以上。
The threadlike branches are often woven together to form a velvety body sometimes longer than 12 in. (30 cm).
近期成功地培养出的水生原植体具有应用前景，然而对其生物学特性尚缺乏认识。
The recently developed aquatic-living colonies bear applied foreground, but little was known about their biological characteristics.
但原植体耐光性比藻丝体强，说明在野外胶鞘对保护发菜免受强辐射伤害有重要意义。
But photostability of thallus is better than that of filament, which means sheath can protect cells form radiation.
那些可进行光合作用和所维生的细胞呈线形结构，但原植体则无根、茎、叶的分化，无输导组织。
The photosynthetic and supportive cells tend to be organized linearly, but a thallus lacks such differentiated specialized structures as stem, leaves, and conducting tissue.
