“…No relevant differences in terms of rainfall rates and average temperature values were observed during the vegetative and reproductive phases in each growing season. Several studies [45,46] highlight that dry conditions during the growing season negatively affect the agronomic performance of safflower. It is well known that safflower is tolerant to drought and heat and that the flowering stage is the most sensitive to environmental stress [7].…”

Safflower (Carthamus tinctorius L.) is a promising oilseed crop for cultivation in central Southern Italy due to its high tolerance to drought and salinity stress and appreciable seed and oil yields. The genetic diversity of cultivars and climate factors can affect fatty acid composition and yield traits. This study aimed to assess the effects of genotype and climate conditions on the productive performance of eight high oleic safflower genotypes under rainfed conditions in Sicily (Italy). These genotypes were compared to the Montola 2000 cultivar, which was used as a reference. Tests were carried out during the growing seasons of 2014–2015 and 2015–2016. The experimental design was a randomized complete block design with three replications. Morphological and yield components were significantly affected by genotype while the year had a significant effect on plant height only. In general, CTI 17 produced the highest seed yield (1.40 t ha−1) and oil yield (0.58 t ha−1). The seed oil content was found on 40.2% of dry matter, on average. The “genotype” factor significantly affected oil content and fatty acid composition. Oleic acid content was on average 66.1% and did not vary greatly over the two growing seasons. The above- and belowground plant parts showed the highest carbon content and the lowest nitrogen content as a percentage of dry matter. The results indicate that, under rainfed conditions, yield parameters of high oleic safflower genotypes can be profitable in southern Italy though significantly dependent upon genotype.

“…Carthamus tinctorius ( C. tinctorius ), also known as safflower, is a promising and versatile industrial crop used in pharmaceuticals, dyestuffs, edible oil products, and animal feeds [ 7 ]. In our previous study, a cell suspension culture system was developed for C. tinctorius to obtain this plant resource more efficiently [ 8 ].…”

Chlorogenic acids (CGAs) are bioactive compounds widely used in the food, pharmaceutical, and cosmetic industries. Carthamus tinctorius is an important economic crop, and its suspension cells are rich in CGAs. However, little is known about the biosynthesis and regulation of CGAs in Carthamus tinctorius cells. This study first elucidated the regulatory mechanism of CGA biosynthesis in methyl jasmonate (MeJA)-treated Carthamus tinctorius cells and the role of the MeJA-responsive hydroxycinnamoyl transferase (HCT) gene in enhancing their CGA accumulation. Firstly, temporal changes in intracellular metabolites showed that MeJA increased the intracellular CGA content up to 1.61-fold to 100.23 mg·g−1. Meanwhile, 31 primary metabolites showed significant differences, with 6 precursors related to increasing CGA biosynthesis. Secondly, the transcriptome data revealed 3637 new genes previously unannotated in the Carthamus tinctorius genome and 3653 differentially expressed genes. The genes involved in the plant signaling pathway and the biosynthesis of CGAs and their precursors showed a general up-regulation, especially the HCT gene family, which ultimately promoted CGA biosynthesis. Thirdly, the expression of a newly annotated and MeJA-responsive HCT gene (CtHCT, CtNewGene_3476) was demonstrated to be positively correlated with CGA accumulation in the cells, and transient overexpression of CtHCT enhanced CGA accumulation in tobacco. Finally, in vitro catalysis kinetics and molecular docking simulations revealed the ability and mechanism of the CtHCT protein to bind to various substrates and catalyze the formation of four hydroxycinnamic esters, including CGAs. These findings strengthened our understanding of the regulatory mechanism of CGA biosynthesis, thereby providing theoretical support for the efficient production of CGAs.

“…Safflower classifies as a plant that can withstand moderate amounts of salt. According to Koutroubas and Papadoska (2005), safflower plants can also be cultivated effectively in regions with relatively low temperatures and in soil that is not very fertile.…”

In order to improve growth, yield components and chemical constituents of safflower plants a field experiment was done at a privet farm in Mansoura, Dakahlia Governorate, Egypt, during winter seasons of 2021/2022 and 2022/2023. Two factors in this experiment were examined, potassium rate (0.0, 24, 48 and 72 kg K2O/feddan) and amino acids types (control, L-tryptophan, phenylalanine and L-tryptophan + phenylalanine each at 150 ppm) as well as their combination treatments. The achieved results indicated that increasing potassium fertilizer rates gradually increased plant height, branch number per plant and total dry weight of safflower, seed yield per plant and /feddan and fixed oil and petals yields per feddan as well as total chlorophyll contents and carthamin content. The highest values in this regard were obtained when plants fertilized with 72 kg K2O/feddan compared to the other rates under study. In addition, utilizing L-tryptophan + phenylalanine each at 150 ppm significantly increased growth and productivity of safflower plants compared to control (un-sprayed plants) and each one individually. Generally, the best combination treatment for improving seed, fixed oil and carthamin yields were achieved with the treatment of L-tryptophan acid + phenylalanine each at 150 ppm and fertilized with 72 kg K2O/feddan.
