The effect of fresh water and sea water with different specific gravities on the survival rate of young sporelings of Porphyra yezoensis Ueda
Abstract:
An experiment concerning the effect of fresh water and sea water with different specific gravities on the survival rate of young sporelings of Porphyra yezoensis Ueda has been conducted. Conchospores just adhered and young sporelings are used as experimental materials in norma conchocelis culture rooms. The main results are as follows. 1. The conchospores just adhered to bolting silk are very sensitive to fresh water. They can not survive even soaking in fresh water for 10 minutes, but the sporelings cultured in sea water for a short time, can tolerate fresh water quite wen. 2. The conchospores germinated and the sporelings of Porphyra yezoensis can survive a wide range of specific gravity of sea water. In normal sea water (specific gravity being about 1.020-1.022)the losing rate of sporelings is minimum, whereas it is much higher when specific gravity of sea water is lower than 1.005.
