Root growth and proton efflux rates of rice seedlings in a greenhouse environment Taxas de crescimento de raízes e de efluxo de prótons em plântulas de arroz em ambiente de casa de vegetação

Growth patterns and mean proton efflux rates (E H+) in roots of rice seedlings (Oryza sativa cv. IAC 47) grown under light conditions in a greenhouse environment were studied. Fifteen days after emergence, seedlings were transferred to pots containing 3.7 L of nutrient solution with 1.43 mmol NNH4+...
