Abstract:
Growth, chlorophyll, net carbon dioxide assimilation (A), stomatal condutance (gs), transpiration rate (E), intercellular dioxide concentration (Ci) and vapor pressure deficit (DPV) in leaves of annatto plants “Bico de Pato”, “Peruana CPATU I”, “Peruana CPATU III” and “Wagner” were observed in initial growth of plants.
Although values of A seemed equivalent, differences of growth, chlorophyll, DPV, Ci, gs and E were verified.
The differences in growth of varieties were resulted probably by alterations in leaf area.
