Abstract:

Chrysanthemum morifolium is one of the ten well-known traditional flowers and an important medicinal crop in China. It possesses abundant germplasm resources and has high ornamental,economic,and cultural value,playing an important role in landscape and horticultural production. Low temperatures,a common abiotic stress,affect the growth,development,ornamental quality,and economic value of chrysanthemums. Therefore,research on cold tolerance in chrysanthemum is essential for improving its quality and promoting its broader application. Nowadays,with the rapid development of omics technologies such as genomics,transcriptomics,metabolomics,as well as high-throughput molecular marker technologies,research on chrysanthemum cold resistance has progressed rapidly. This review systematically summarizes advances in chrysanthemum cold-tolerance research from the perspectives of phenotypic traits,physiological and molecular mechanisms,and breeding,aiming to deepen our understanding of the mechanisms underlying cold tolerance and provide a theoretical basis for chrysanthemum utilization and breeding.

Key words: chrysanthemum, low-temperature stress, cold tolerance, physiological mechanisms, molecular mechanisms
