应用不同来源及不同培养状态的坛紫菜自由丝状体,进行了初步的发育诱导试验。结果表明:可以在室内诱导紫菜自由丝状体的发育,使处于不同生长状态的坛紫菜自由丝状体从营养藻丝转化为孢子囊枝,转化的速度与原来的生长状态有关。不同的品系的自由丝状体在相同的诱导条件下,表现的结果是不一样的,应用于栽培生产的自由丝状体容易形成孢子囊枝。温度是诱导自由丝状体发育的重要因素。PO_4~3-P的添加量为20～30m g/L范围内,自由丝状体出现孢子囊枝的时间接近,当PO_4~3-P的添加量超过40m g/L或少于20m g/L以后,对自由丝状体的发育不利。
The application of different sources and different culture state of the algae Freeweed filamentous larvae, conducted a preliminary developmental induction test. The results showed that it could induce the development of free larvae of Porphyra yezoensis indoors, and transform the free filamentous body of Porphyra yezoensis from vegetative hyphae into sporangium branches in different growth states. The rate of transformation was related to the original growth state. Different strains of the free filament in the same induction conditions, the performance of the results are not the same, used in the production of free filaments easy to form sporangia. Temperature is an important factor inducing the development of free filaments. When the amount of PO_4 ~ 3-P added was in the range of 20 ~ 30 m g / L, the time of sporocyst shoots appeared in free filaments. When the amount of PO_4 ~ 3-P was more than 40 m g / L or less than 20 m g / After L, the development of free filaments adversely.
