Development of Endosperm-based Basal Media for Micropropagation of sago palm (Metroxylon sagu)

Sago palm (Metroxylon sagu) is well known as the highest producer of starch plant. High demand of sago starch requires intensify planting of sago. Tissue culture is one promising method for mass propagation of planting materials. Works on sago palm regeneration through tissue culture propagation had...

Tissue culture is one promising method for mass propagation of planting materials. Works on sago palm regeneration through tissue culture propagation had been successfully achieved via somatic embryogenesis.
