Leaf nitrogen supply improves sugarcane photosynthesis under low temperature
Cerqueira, G.; Santos, M. C.; Marchiori, P. E. R.; Silveira, N. M.; Machado, E. C.; Ribeiro, R. V.This study aimed to test the hypothesis that increases in leaf nitrogen concentration would reduce the sensitivity of sugarcane photosynthesis to low temperature. IACSP95-5000 plants were grown inside a growth chamber at 30/20oC (day/night) and we evaluated the effects of leaf nitrogen spraying (2.5% urea) on plants facing low temperature (22/12°C) for eight days. The leaf nitrogen supply increased leaf nitroge...
