We investigated the effects of a highly saline solution (HS) containing hypochlorous acid, calcium chloride (CaCl2),
and phosphoric acid (H3PO4) on cell death and growth rate of laver Porphyra yezoensis and green laver Ulva intestinalis.
Cell death rates of laver treated with HS and HS plus hypochlorous acid (HS + HOCl) in the harvesting stage
were less than 0.5%, and there were no significant differences between the HS and HS + HOCl treatments. However,
cell death of green laver treated with HS + HOCl in the harvesting stage was greater than 81.2%. These results indicate
that the addition of HOCl is highly effective to eradicate noxious green laver without causing damage to laver.
The addition of HOCl and H3PO4 to HS did not increase the area or weight of laver blades. A combination treatment
of CaCl2 and HS, however, significantly increased the area and weight of laver lades compared to controls (P<0.05).
