Direct regeneration of plantIets from immature inflorescence of ginger (Zingiber officinale Rose.) by tissue culture

Abstract

Immature inflorescences of ginger when cultured on MS revised medium supplemented with 10 mg I-L BA and 0.2 mg1-1 2, 4-D resulted in the conversion of floral buds into vegetative buds and these later developed into plantlets directly without intervening callus phase. About 38% ofthe buds produced multiple shoots ranging from 5-25. When individual flowers were cultured separately on the same medium plantlets developed from the ovary in 45% of cases. These plantlets were maclli to develop good root system on MS medium with 1 mg P NAA. These rooted plantlets established easily in the soil. In some of the cultures the ovaries developed into fruits.
