Histogênese de calo de explante caulinar de Datura insignis Barb. Rodr.

Abstract: Resumo Calos não-homogêneos e compactos foram induzidos a partir de explantes Internodais de Datura insignis Barb. Rodr. cultivados em meio B5 (Gamborg, 1968) suplementado com 1mg/l BAP + 0,25 e 1mg/1 NAA. A análise histológica do calo revelou que, embora tenham ocorrido divisões periclinais na epiderme, no colênquima e no parênquima cortical, interfascicular e medular, apenas os tecidos situados entre a epiderme e o cilindro central transformaram-se em tecido calogênico. Constatou-se a diferenciação de elemen… Show more

“…cytodifferentiation, which gives the way for organogenesis (Figure 2B & 2C). Similar results have been reported by Arumugam & Rao (2000) in Aegle marmelos and by Figueiredo et al (1989) in Datura insignis. In the section of embryogenic callus showed differentiated shoot buds formation and the development of embryoids (Figure 2D & 2E).…”

“…A similar process was reported by Gautheret (1957) in Amorphophallus rivieri. Figueiredo et al (1989) detected that only the cortical tissue was transformed into callus in Datura insignis. They also observed that the meristematic centers were always formed close to the starch accumulating cells.…”
