| ABSTRACT Nidularium procerum and Nidularium innocentii (Bromeliaceae) were cultivated in vitro on media supplemented with different sources and levels of GA3 (gibberellic acid). These sources were the commercial powder (analytical degree) and fermented extract obtained by Fusarium moniliforme via solid state fermentation. The in vitro elongation and rooting of these plants were evaluated after 50 days of cultivation. The GA3 present in the fermented extract possess the same effect of purified GA3 (analytical degree) for the increase of the height of aerial part of shoots of N. innocentii, but not for the N. procerum being the GA3 fermented extract in a lesser degree. The GA3 fermented extract influences negatively the rooting in N. innocentii, while GA3... |

| O presente trabalho objetivou estimar parâmetros, correlações e ganhos genéticos para caracteres de crescimento e forma, em um teste de progênies deEucalyptus camaldulensis na região centro-oeste do Brasil. Aos três anos de idade, as progênies foram avaliadas quanto aos caracteres: altura total (ALTT), altura comercial (ALTC), diâmetro à altura do peito (DAP) e forma de fuste (FF). A análise de deviance detectou diferenças significativas para os caracteres ALTC, DAP e FF. As estimativas das herdabilidades individuais foram de baixa magnitude para ALTT (0,10) e DAP (0,16), porém, ALTC (0,18) e FF (0,25) apresentaram valores de média a alta magnitude. Os coeficientes de variação genética individual (CVgi%) variaram de 8,59% para FF a 15,91% para ALTC. As... |

| ABSTRACT: Cochlospermum regium roots are used in popular medicine and its extract has diverse phytochemical molecules some with antimicrobial activity, consequently exposing this specie to genetic erosion risks. Thus, the objective of this study was to develop an in vitro multiplication protocol using chemical sterilization of culture medium. Therefore, explants obtained from apical buds of C. regium seedlings were inoculated into with 0.05mg L-1 NAA and 1mg L-1 BAP sterilized by chemical agent sodium hypochlorite (NaOCl) at 0.001%, 0.003% and 0.005% of active chlorine (Cl). Autoclaved culture medium was used as control. Result showed that the contamination by bacterial at 91 days of cultivation was significantly (P<0.05) controlled by autoclaving,... |
