Growth and regeneration of plantlets in callus cultures of pineapple

Callus cultures were established from the basal region of in vitro-obtained shoot buds on MS medium supplemented with CH + CW + NAA. Such callus cultures, when grown on MS medium devoid of any growth regulators, regenerated shoot buds and optimum regeneration was obtained on MS + CW (5% v/v) medium. Addition of BA did not enhance shoot bud regeneration, but two variants (albino types) were observed among the BA-induced regenerants. The callus-regenerated shoot buds produced multiple shoots when transferred to MS + NAA + IBA + K medium. The plantlets were induced to root on a modified White's medium + NAA + IBA and subsequently transferred to soil.
