| Four papaya genotypes, two from the Solo group (Sunrise Solo TJ and Improved Sunrise Solo line 72/12) and two from the Formosa group (Tainung 02 and Know You 01) grown in ultisol under field conditions in Macaé, RJ, Brazil, were used in this study. Two different effective depths (ED) were determined in the area using a penetrographer with average soil moisture of 11.2%. The area with ED of 0.35 m with a maximum pressure of 4.12 MPa for penetration was defined as an area with restriction (WR) to root growth, while, the area with minimum ED of 0.60 m and a pressure lower than 2.30 MPa as an area with no restriction (NR). The net CO2 assimilation rate (A), stomatal conductance (g s), leaf temperature (Tl), intercellular partial pressure of CO2 (c i) and... |

| RESUMO O objetivo deste trabalho foi avaliar a eficiência da esterilização química do meio de cultura e de agentes geleificantes alternativos e sua influência no desenvolvimento in vitro e ex vitro de plantas de abacaxizeiro ‘Vitória’. O meio de cultivo utilizado foi composto pelos sais do MS e vitaminas de White, com 30 g L-1 de sacarose e 100 mg L-1 de mioinositol. Foram realizadas duasformas de esterilização dos meios de cultivo e das vidrarias: em autoclave a 121°C e com solução de hipoclorito de sódio (NaClO) a 0,003% para enxágue das vidrarias e 0,0003% no meio de cultivo. Os agentesgeleificantes testados foram: M1: ágar (6,0 g L-1); M2: amido de milho (60,0 g L-1); M3: ágar (3,0 g L-1) + amido de milho (30,0 g L-1) e M4: ágar (3,0 g L-1) + amido de... |

| In this research, was used four papaya (Carica papaya L.) genotypes: three from the 'Solo ( Sunrise Solo TJ, Sunrise Solo 72/12 and Baixinho de Santa Amália) group and one from the 'Formosa' group (Know-You 01). They were grown in plastic pots containing a sandy-clay-loam soil subjected to pH correction and fertilization, under greenhouse conditions. Throughout the experimental period plants were subjected to periodic irrigation to maintain the soil humitidy around field capacity. The experiment was conducted 73 days after sowing. In all genotypes, leaf gas exchange characteristics were determined. The net photosynthetic rate (A, mumol m-2 s-1 ), stomatal conductance (g s mol m-2 s-1), leaf temperature (T I, 0C) and intercellular carbon dioxide... |
