Abstract:Nitrogen plays a vital role in regulating leaf senescence and yield formation in rice (Oryza sativa L.). However, little information is known about the effects of N rates on the growth and grain yield of rice plants with leaf early senescence. This study used a leaf early-senescent rice mutant (osled) and its wild type (WT) (93-11) and investigated how N rates of 0 kg ha -1 (0N), 240 kg ha -1 (240N), and 360 kg ha -1 (360N) influenced the main agronomic and physiological performance of the mutant osled.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
