Unveiling sunflower morphological and phenological adaptations to drought stress

Abstract

Drought stress significantly threatens crop productivity worldwide, requiring a comprehensive understanding of plant adaptations to alleviate its adverse effects. Sunflower, as an important source of edible oil, is greatly affected by drought in different developmental stages. This review investigates the morphological aspects and phenological adaptations of sunflower under drought conditions. Through a detailed description of morphological and phenological changes in sunflower, induced by drought, we aim to unravel the plant’s strategies for coping with water scarcity. In addition, the study describes genetic background of drought tolerance in sunflower, as well as insight about valuable genetic resources. Finally, we have described drought mitigation mechanisms known in sunflower, through morpho-physiological adaptations and agricultural practices which can alleviate the effect of drought. As a future strategy this research emphasizes the importance of genetic diversity in cultivating drought-resilient sunflower, using modern breeding techniques through genomic selection and omic’s technologies as a promising strategy in the face of escalating water limitations and development of drought tolerant and tenacious sunflower.
