Procedures for recovering cassava clones distributed in vitro
Plant tissue culture includes a wide range of techniques: protoplast, cell, anther, callus, meristem and organ culture, all having one common factor: the growth of vegetative material in an aseptic environment; i,e., the sterilized culture medium in test tubes. In spite of the fact that several o...
Methods of vegetative reproduction are discussed using the results obtained with cassava and potato. Results of clone cleaning by heat therapy and in vitro meristem culture are given. Two methods for rapid cassava multiplication are proposed: by sprouts from cuttings and single leaf cuttings, whi...
