Capacidade de combinação entre linhagens de milho visando à produção de milho verde [PDF]

Bragantia, 2009
No Brasil, há escassez de informações sobre a avaliação e obtenção de cultivares destinadas à produção de milho verde, bem como estudos genéticos de características envolvidas nesta produção. Deste modo, este trabalho teve por objetivo determinar o tipo de ação gênica predominante no controle das características e estimar a capacidade geral de ...

Alterations in plant architecture and physiology allow maize to sustain yield after early defoliation

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Maize (Zea mays L.) tolerance to early defoliation is shaped by genotype‐specific physiological and morphological responses. Defoliation disrupts the source–sink balance, altering carbon allocation and plant development. Understanding these responses is crucial for optimizing breeding programs and agronomic management.

Partitioning between primary and secondary metabolism of carbon allocated to roots in four maize genotypes under water deficit and its effects on productivity

Crop Journal, 2015
Plants may respond to drought by altering biomass allocation to shoots and roots or by changing the metabolic activities in these organs. To determine how drought changes the partitioning of carbon allocated to growth and secondary metabolism in maize ...
