Abstract Water deficit is one of the major constraints to the establishment and early growth of cacao (Theobroma cacao L.), particularly under increasingly frequent and intense drought conditions. The objective of this study was to evaluate the morphological and physiological responses of cacao seedlings subjected to progressive water deficit under nursery conditions. Plants were evaluated over a 45-day period without irrigation and compared with well-watered plants maintained at 60% of substrate field capacity. Growth variables, photosynthetic pigment concentrations, and proline accumulation in leaves, stems, and roots were evaluated. Stem length showed no significant differences between treatments, whereas… More >
