Relationship between Delayed Leaf Senescence (Stay-Green) and Agronomic and Physiological Characters in Maize (Zea mays L.)

Stay-green (SG) is a term used to describe genotypes that have delayed leaf senescence as compared reference genotypes. SG could be favorable for grain yield, silage yield and quality, double exploitation (grain feed stover bioenergy), stress resistance, etc. However, some studies show contradictory results regarding the influence of or in uptake remobilization nutrients moisture grain. This experiment aimed study impact inbred lines maize assess potential exploitation. We also N dry matter from evaluated 16 with contrasting expression field at two locations Galicia 2017. confirmed functional, meaning maintained photosynthesis activity lengthy period. Coordinated senescence, filling was 9 days longer than NSG took up more after flowering, although and, general, kernels less efficient. higher compensated poor remobilization, final effect on content favorable. kernel weight were 20% heavier NSG. The genotypes, indicating breeding purpose bioenergy).
