| description | Expansion into areas outside their centres of origin requires knowledge of quinoa's physiology and its response to the environment concerning the determination of seed yield and its numerical components to facilitate crop management and breeding. The objectives of the current work were to analyse the determination of seed weight (SW) of different quinoa genotypes adapted to temperate climates (Sea‐level type) under a wide range of growth conditions through: (a) the analysis of seed growth rate (SGR) and seed filling duration (SFD) variation, (b) the study of seed's water dynamics, and (c) the analysis of the effect of environmental conditions on SW components and water dynamics. For this, four genotypes were planted under four environments, as a result of the combination of sowing dates and growth conditions (field or greenhouse). Variation in SW was a result of a change in SGR (r2 = .66; p |
