“…These results are in agreement with those of Ashrafi and Razmjoo (2010) in safflower and Dornbos and Mullen (1992) in soybean, who also observed oil content reductions due to drought stress. Oil concentration is not only affected by drought stress but was also shown to highly depend on the genotype (Blum, 1997).…”

Safflower is one of the most adapted oilseed crops to the drought-prone arid lands. This experiment was carried out to evaluate the effects of water deficiency on some physiological traits such as proline content, soluble carbohydrate content, relative water content (RWC), and seed quality using 64 safflower genotypes grown under normal and water-deficient field conditions. Plants were grown under normal irrigation until the branching growth stage, when water deficiency was applied to the plants. Results of combined analysis of variance showed the significant effects of genotype, water deficiency, and their interactions on the tested traits. RWC, seed oil content, and oil yield significantly decreased whereas proline, soluble carbohydrate, and protein content increased in response to water deficiency. Cluster analysis divided genotypes into 3 groups of sensitive, tolerant, and semitolerant genotypes under water-deficient conditions. The second group (tolerant group) possessed the lowest seed yield loss due to water stress and produced the highest seed protein content and seed oil yield under water-deficient conditions. The superior seed yield and quality was closely related to the physiological properties of the plants, resulting in higher leaf proline, carbohydrate, and RWC under water-deficient conditions. The results suggest that leaf proline content, carbohydrate content, and RWC would be useful traits to select for water stress-tolerant plants in safflower.

“…We observed that drought globally reduces sesame seed oil content of the five genotypes but the remaining seed components fluctuated according to the genotypes. Similar findings were reported in other important oilseed crops such as canola [46], soybean [47] and safflower [48].…”

Abstract:Sesame is an important crop in West and Central Africa playing a role of an alternative cash crop for smallholders. However, sesame productivity is highly impaired by drought. This study aimed at identifying some drought-resistant genotypes and efficient screening traits in large sesame germplasm. Ten genotypes were examined based on 21 biochemical, physiological, agromorphological and seed quality traits under three weeks of water stress. A high variability for drought resistance was observed among the genotypes. The genotypes WC17, WC18 and WC14 were drought resistant, WC12, WC13, WC06 and WC03 were moderately drought resistant while, WC02, WC10 and WC08 were drought sensitive, based on principal component analysis. The resistant genotypes exhibited both avoidance and tolerance features including increase of the root system, reduced water loss, highest activity of antioxidative enzymes and accumulation of proline. They produced higher biomass and had higher ability to maintain seed quality under drought stress compared with the sensitive genotypes. Strong accumulation (~200% ratio stress/control) of biochemical markers including superoxide dismutase, ascorbate peroxidase, catalase and proline could be regarded as an important indicator for selecting drought resistant genotypes. This study represents a reference for future research towards developing new varieties with improved drought resistance in West and Central Africa.

Safflower is one of the oldest cultivated crops, usually grown at a small scale. Safflower is grown for flowers used for coloring, flavoring foods, dyes, medicinal properties, and livestock feed. Safflower is underutilized but gaining attention due to oil yield potential and the ability to grow under high temperatures, drought, and salinity. Salinity and drought have negative effects by disrupting the ionic and osmotic equilibrium of the plant cells. The stress signal is perceived by membranes then transduced in the cell to switch on the stress responsive genes. This review discusses on stress tolerance mechanisms in safflower. Strategies are proposed for enhancing drought and salt resistance in safflower.
