Sterility of basal spikelets in wheat: predetermined fate or a matter of resources?

Journal of experimental botany - 4 Dec 2024

Tamagno Santiago, Carrera Constanza S, Marchese Sofia I, Savin Roxana, Slafer Gustavo A

Abstract excerpt

Grains per spike in wheat (Triticum aestivum L.) are not uniformly distributed. Basal spikelets are typically sterile (or rudimentary) under common agronomic field conditions leading to the assumption that this is a constitutive trait. Yet, it is unknown whether high resource availability per plant could prevent floret mortality in basal spikelets. We present data from two field experiments assessing spike...
