Study of Seaweed Kappaphycus alvarezii Explants Growth in the Different Salinity Concentrations

HighlightThe best salinity for the thallus growth of K. alvarezii is 32 mg/LThe indicates osmotic balance seaweedThis osmoregulation process affects nutrient absorption study aims to develop availibility superior seeds alvareziiAbstract Kappaphycus one leading commodities in Indonesian waters. Demand this commodity quite high, as reflected increasing volume exports each year. Fulfillment these demands obtained from production cultivation. Generally farmers get natural seaweed seedlings, namely cuttings existing seaweed. The continuous use nature can cause deterioration quality and quantity. Handling problem originating nature, be overcome by multiplying through tissue culture methods vitro. In term techniques method, most important thing note environmental parameters. An environment parameter that changes suddenly such inhibit Thus, work attampting different treatment on explants alvarezii. This at determining (weight) with a comparison levels vitro method. method used was completely randomized design (CRD) treatments 30, 31, 32, 33, 34 ppt. results showed salinities influenced rate explant 31 ppt, while lowest value ppt
