About

Research group, authors, and funding information.

Research group

This work was developed at the NEPEM – Núcleo de Estudos em Pesquisa e Experimentação com Milho (Study Group on Research and Experimentation), within the Department of Plant Science (Departamento de Fitotecnia) of the Federal University of Santa Catarina (UFSC), Florianópolis, Brazil.

Study location

Experiments were conducted at the Centro de Ciências Agrárias (CCA/UFSC), Florianópolis, Santa Catarina, Brazil (27°35’S, 48°31’W; 2 m a.s.l.). The subtropical climate of the region is classified as Cfa (Köppen) — humid subtropical with hot summers and mild winters — making it an important testbed for cool-season crops such as flax.
