[In vitro regeneration and applications using vegetable cell and tissue culture].

Abstract

Plant cells by means of their totipotency and aided by in vitro culture techniques can be induced to perform morphogenesis leading to somatic embryoids and massive clonal multiplication; microspores or pollen can be triggered to recover haploid plants, then characters expressed via haploidy can be selected and fixed. Protoplasts from different species can lead to recombinations. We report here work done on Carica pubescens, where somatic embryoids were obtained from cells; in Prunus avium androgenesis leading to pollen calli was triggered, while plants were recovered from Nicotiana tabacum anthers. Fusion products were obtained using C. pubescens and C. papaya protoplasts, leading up to calli and shoots.
