Study of seaweed kappaphycus alvarezii explants growth in the different salinity concentrations

Abstract

In term of tissue culture techniques method, the most important thing to note is environmental parameters. An environmental parameter that changes suddenly such as salinity can inhibit the growth of seaweed. Thus, this work is attempting the different salinity treatment on seaweed (Kappaphycus alvarezii) explants. This study aimed to determine the explants of K. alvarezii with a comparison of the different salinity levels in the in vitro tissue culture method. The method used in this study was Completely Randomized Design (CRD) with different salinity treatments namely 30, 31, 32, 33, and 34 mg/L. The results showed that different salinities influenced the growth rate of K. alvarezii seaweed explants with the highest explant growth rate was 31 mg/L and the lowest was 34 mg/L.
