Malavolta, E.; Parada, A.; Martins, G.; Gonçalves, J.C.; Centurion, J.F.; Vasconcellos, L.A.B.C.; Almeida, M.; Marchetti, M.E.; Pereira, O.A.P.Dry matter production and accumulation of macronutrients were studied by growing plants in nutrient solution and taking samples at given physiological intervals. It was found that curves describing dry matter production and uptake were sigmoidal in tendency. Maximum rate of uptake was observed within a 2-month period starting at full tillering and ending at the stage of panicle formation. Leaf levels of N, P, a...

Malavolta, E.; Parada, A.; Martins, G.; Gonçalves, J.C.; Centurion, J.F.; Vasconcellos, L.A.B.C.; Almeida, M.; Marchetti, M.E.; Pereira, O.A.Rice plants, varieties IAC-164 and IAC-165 weree grown in number 2 Hoagland's solution, full strength, and with excess of Al and Cl. Nitrate reductase (RNO3) activity was assayed in the leaves one month before harvesting. When the grains were already dry, plants were harvested, the mineral contents of the organs was determined, and crude protein in the grains was also determined (semi micro Kjeldahl). Statistic...
