A method is provided for the regeneration of an individual coconut plantlet. It comprises culturing a tissue explant of an undifferentiated male flower of a coconut tree in a culture medium, which contains 10-50 ppm of an auxin, 0.1-3% of a polysaccharide produced by a bacterium of Pseudomonas and 0.05-1% of activated carbon, in a dark place until a shoot-like structure appears; and then culturing under exposure to light of 3,000-20,000 luxes while repeating its subculture in a fresh culture medium.

A novel acidic heteropolysaccharide which comprises as its structural units arabinose, mannose, galactose, glucuronic acid, and xylose, at a specific ratio. The polysaccharide can be prepared by culturing a callus induced from a plant belonging to the genus Polianthes L. in a culture medium containing plant hormones. The polysaccharide can be used as a component of agents for external application and detergents, and provides good moisturizing effects and a smooth, satisfying feeling upon use. When formulated in detergents, they produce remarkable improvement in a clean, rich feeling upon use.
