PROBLEM TO BE SOLVED: To provide a molar osmotic pressure culture method of seaweed, especially, a method of realizing artificial culture target by a method of immobilizing planktonic reproductive cells released from wild large seaweeds and mass-producing.;SOLUTION: The artificial culture target, stable and mass-producible, is obtained by collecting seaweeds (such as wild sea lettuce), stimulating with different molar osmotic pressures (salinity) by an artificial method to release planktonic reproductive cells and adhering the reproductive cells, and thereby, the seaweeds are advantageously produced and much provided as a source of biomass energy material.;COPYRIGHT: (C)2008,JPO&INPIT
