Use of plant biotechnology for the propagation of threaten cataceas.

Abstract

The quick readiness of postures for the restoration of the vegetable cover in a degraded ecosystem constitutes one of the main factors in the ecological restoration programs. The in vitro tissue culture techniques are attractive for the propagation of threatened species, due to the discharges multiplication rates that are gotten in a relatively short time and to the reduced required departure material and from this point of view it is considered to the cactaceae like the family more worked. Cuba has a wide vascular flora, in which stand out diverse cactuses goods, but the same as other countries of the tropic have a great destruction of their habitat due to the man’s devastating action, so that the development of alternative techniques as tissue culture can help to counteract the loss of the biodiversity in the Cuban flora. Key word: micropropagation, extinction danger, biodiversity conservation, in vitro tissue culture
