Investigating the effects of exogenous factors on growth, photosynthetic pigments and bud induction in Gracilaria corticata var. cylindrica under in vitro conditions

Effect of kind and concentration of culture media, and plant growth regulators on in vitro response was studied in an economically important seaweed species viz. Gracilaria corticata var. cylindrica. Filter sterilized autoclaved artificial seawater medium at 100 % concentration (A2) was found to be the most optimum for in vitro culture as the cultured explants showed superiority in terms of growth and photosynthetic pigment content, apart from inducing lateral bud formation.
