Genetic Regulation of Maize and Sorghum under Abiotic Stress
Climate extremes of temperature, drought and flooding continue to challenge global agricultural production and food security. If modeling studies are accurate, climate variability and drought will be a more prevalent occurrence in the future, not only inhibiting grain yield but also stressing water …

Capacidade combinatória e diversidade genética em sorgo granífero
… (ACAM), incidência de antracnose (ANT), stay green (SG) e produtividade de grãos (PROD). Para a análise dialélica, adotou-se o método 4 de Griffing (1962) adaptado a dialelos parciais. As análises de diversidade genética realizadas foram o método UPGMA e agrupamento de Tocher modificado. …

Characterization of the effect of nitrogen deficiency on above-ground plant phenotypes in relation to root complexity in maize
… genome for some N stress indicative traits (e.g. stay-green). This research and related projects are essential to a better understanding of plant N uptake and metabolism. Understanding these processes is a necessary step in the progress towards the goal of breeding for better NUE crops.

Genetic and agronomic approaches for improving nitrogen use and maize productivity
… to greater post-flowering N uptake and enhanced stay-green. In conclusion, genetic and agronomic approaches for improving maize N use and productivity should focus on i) grain yield at low N (stress tolerance and yield stability), and ii) enhancing fertilizer N use through strategies that …

Physiological aspects of relative changes in nitrogen and plant density stress tolerances over a 38-year period of US maize hybrid introductions
… by advancing silking and extending functional stay green in maize leaves); stronger source and sink during grain filling; enhanced tolerance to higher density; and canopy architecture changes. Newer hybrids were known to accumulate more dry matter and nitrogen in the post-silking period, but …
