t0“Physiological Changes and Yield Components of Safflower (Carthamus tinctorius L.) Lines as a Function of Water Deficit and Recovery in the Flowering Phase”
e7“IMA 04, IMA 14, and IMA 21 were considered tolerant because their physiological variables and yield components were less affected by water restriction, and they also showed recovery after rehydration compared to IMA 02”

Other claims from this paper (12)
- Intervention effect Water deficiency decreased relative water content, water potential and photosynthetic pigment contents in safflower.
- Intervention effect Water deficiency decreased photosynthetic performance and the maximum and potential quantum yield of PSII in safflower.
- Intervention effect Water deficiency decreased electron transport rate and photochemical quenching in safflower.
- Intervention effect Water deficiency increased electrolyte leakage, water use efficiency and non-photochemical quenching in safflower.
- Intervention effect Water deficiency caused reductions in the number of capitula, 100-grain mass and harvest index in safflower.
- Mechanism Decreases in photochemical efficiency and photosynthetic performance explain the reductions in yield components under water deficiency.
- Intervention effect Under water deficiency, IMA 02 showed more significant reductions in capitula number, 100-grain mass and harvest index.
- Observation IMA 02 was considered susceptible to soil water changes.
- Intervention effect IMA 04, IMA 14 and IMA 21 showed recovery after rehydration, compared with IMA 02.
- Observation IMA 04, IMA 14 and IMA 21 were considered tolerant to water restriction.
- Recommendation These safflower lines can be recommended for commercial use.
- Recommendation Safflower breeding programs should select superior genotypes under drought conditions.
