Abstrakt: Abstract. The sensitivity of stomata to water stress increased during ontogeny of primary bean leaves growing under constant environmental conditions:the decrease in both adaxial and abaxial epidermal conductances was induced by slightly more negative values of leaf water potential in young than in mature and especially old leaves. However, these differences were less expressive than the differences mentioned in the literature for leaves of different insertion level, where adaptations to microelimatic conditions in different canopy layers in addition to ontogeny may occur.
