Se ha documentado variabilidad genotípica en el impacto del estrés térmico durante etapas reproductivas del maíz sobre el número, peso y calidad de los granos. Sin embargo, se desconoce el efecto del estrés térmico en pre-floración sobre el peso y la calidad cuando hay cambios en la relación fuentedestino post-floración, i.e. defoliaciones. El objetivo de este trabajo fue analizar la evolución del peso de los granos de maíz y su calidad para un híbrido tropical (H1) y sus dos líneas parentales (L1 y L2), ante un evento de estrés térmico pre-floración combinado con reducciones de la fuente de asimilados post-floración. Se realizó un experimento bajo condiciones de invernáculo que permitió manipular el régimen térmico (con y sin estrés). El e...
