Conteúdo: | Leaf age effects on the leaf conductance to water vapour diffusion of the adaxial and abaxial leaf surfaces were measured in the morning andin the afternoon on 17 different plantain and banana (Musa sp.) genotypes. The irradiance levels increased three-fold while leaf to air vapour pressure deficit levels increased two-to four-fold from morning to afternoon during the sampling period in a field site located in the humild forest-moist savanna transition zone of Nigeria. Conductance values were reduced in older, and senescing leaves relative to the young and mature leaves both in the morning and in the afternoon. Conductances were higher for the abaxial leaf surfaces than the adaxial surface and higher in the afternoon than in the morning, with some genotipe differences.
