Abstract

Crop ecophysiology analyzes the behavior of plant populations in interaction with their environment. This discipline integrates concepts from plant physiology, agronomy, and ecology to develop management strategies for farmers and guide the genetic improvement of crops. The inception of Argentine research in sunflower ecophysiology almost coincides with the beginning of ecophysiology research in the country. Pioneering contributions to the international literature on sunflower by Argentine authors date back to 1985. To date, Argentine researchers have authored a total of 184 papers on sunflower ecophysiology in international journals, with an average publication rate of 5.7 papers per year during the period 2021–2023. This research has addressed a wide range of topics, including phenology, the eco-physiological and numerical determinants of yield and quality, the effects of abiotic factors on these determinants, the optimization of management practices for resource-limited environments, and genotype × environment interactions, among others. Currently, sunflower is regarded by Argentine farmers as a medium- to low-yield crop, often used as an alternative to soybean and maize in situations where these crops cannot be cultivated. However, advances in ecophysiological research in Argentina have the potential to enhance sunflower's competitiveness relative to other grain crops. The knowledge accumulated through crop ecophysiology and associated disciplines (e.g., ecology, agronomy, plant breeding, molecular biology, and genomics), along with significant methodological advances in testing techniques and data interpretation, offers an encouraging outlook for addressing the challenges of sunflower production.

Keywords: Argentina ecophyisiological research on sunflower; main research topics; future challenges of ecophysiological research on sunflower in Argentina
