英文摘要	Despite being native to semi-arid environments, safflower (Carthamus tinctorius L.) growth, seed yield, and physiological responses under contrasting temperature and moisture conditions typically occurring in semi-arid regions are not fully understood. Thus, three field experiments and a greenhouse study were conducted to study the growth, yield, and physiological attributes of six safflower genotypes under different environmental conditions. Spring-sown and summer-sown plants were subjected to contrasting environmental conditions in two 4-replicate randomized complete block design (RCBD) field experiments. In the third field experiment (a 3-replicate split plot RCBD) and the greenhouse study (a 3-replicate RCBD), the safflower genotypes were subjected to different irrigation regimes of no stress to severe drought. Spring-sown safflower outperformed the summer-sown crop in terms of seed filling rate (SFR) by 93%, seeds head(-1) by 62%, 1000-seeds weight by 30%, seed yield by 53%, oil concentration by 16% and protein concentrations by 22%. Plant dry mass (PDM) for the summer-sown safflower was 25% greater than the spring-sown one. In contrast to a 21% increase in seed protein concentration, severe drought led to notable decreases in leaf chlorophyll a (chl-a), chl-b and total chlorophyll (chl-tot) concentrations, leaf area, relative water content (RWC), catalase (CAT) and ascorbate peroxidase (APX) activities, membrane stability index (MSI), oil concentration, yield components and consequently seed yield (36%) and PDM (34%). Genotype Kouseh tended to maintain its seed yield and quality across the environmental conditions, potentiating this under-utilized crop as an alternative to be endorsed in crop rotations of semi-arid climates.
