研究在室内可控条件下,不同品种条斑紫菜在同一外界环境条件下自由丝状体生长率和同一品种在不同外界环境条件下钻孔率的差异.结果表明,当海水比重为1.020～1.023,水温为15～25℃的条件下,不同品系的条斑紫菜生长率和钻孔率存在明显的差异.按生长率由高到低依次为Y叶隐94-1>YW92-1>Y95-1>YSI>YMI>YLII;不同比重下钻孔率由高到低依次为YSI>YLII>YMI>YW92-1>Y叶隐94-1>Y95-1;不同pH值下钻孔率由高到低依次为YSI>YMI>YLII>YW92-1.
The results showed that when the proportion of seawater was 1.020 ~ 1.023, the difference of the rate of free filamentous growth of different varieties of Porphyra yezoensis under the same external environment and the drilling rate of the same species under different external environmental conditions were studied under indoor controllable conditions. , The water temperature of 15 ~ 25 ℃ under different conditions, the growth rate and the drilling rate of Porphyra yezoensis differed significantly.According to the growth rate from high to low were Y Ye Yin 94-1> YW92-1> Y95- 1> YSI> YMI> YLII. The drilling rates from high to low were YSI> YLII> YMI> YW92-1> Yye94-1> Y95-1 under different specific gravities; The order is YSI> YMI> YLII> YW92-1.
