(1)We treated the seedlings of Laminaria japonica with MnCl2 solution in various conceiitrations of 5,10,20,50,100,200 ppm.When treated with low concentrations of MnCl2 solutions of 5,10,20,50ppm,the growth of the seavreed both in length and in weight is evidently enhanced,The optimum concentrations are 10 and 20 ppm.Higher concentrations,such as 100,200 ppm,are inhibiting to the growth of the plant.But at the time of harvest,the contents of carbon,nitrogen and phosphorus of all the seaweed treated with various concentra ons of Mn are higher than that of the control group.The carbon and nitrogen contents are the highest in the 10 and.20 ppm Mn treated groups,and ph sphorus contents are the highest in the 20 and 50 ppm Mn treated groups.
