Chrysanthemum plasticity for postharvest behaviour

A research by China researchers demonstrates he rich resources of the genetic material related to postharvest behaviour. The work in this case uses 275 cut chrysanthemum germplasm, from which a total of 7 elite germplasms with strong storage tolerance and prolonged vase life were identified.

Objective

Enhancing storage tolerance and extending vase life constitutes the core objective of postharvest preservation research for cut flowers. This study aims to systematically evaluate and screen cut chrysanthemum (Chrysanthemum × morifolium) cultivars with superior storage tolerance and vase performance, thereby laying a robust material foundation for postharvest quality improvement and breeding of new cut chrysanthemum cultivars.   

Method  

A total of 275 cut chrysanthemum germplasm resources were used as research materials. Postharvest preservation-related indicators during the dry storage period and vase period were determined. The storage tolerance and vase performance of cut chrysanthemums were analyzed and evaluated by using difference analysis, variation analysis, correlation analysis, cluster analysis and principal component analysis.   

Result  

There were significant differences in postharvest storage tolerance and vase ornamental performance among different cut chrysanthemum cultivars. ‘Nannong Hongyi’ ‘Qinhuai Ruixue’ and ‘Pip’ had excellent storage tolerance, long vase life and outstanding comprehensive traits, which were suitable for promotion and application as main cultivars with good storage and transportation resistance and long ornamental period. ‘Nannong Lifengche’ and ‘Nannong Binyun’ had prominent storage tolerance, which were suitable for long-distance transportation and long-term storage, and could be used as excellent parents for breeding export-oriented cut chrysanthemum cultivars. ‘Nannong Hongdiandian’ and ‘Rongshan’ had a long vase ornamental period; although their storage tolerance was relatively poor, they were very suitable for localized high-quality production and could be used as key parents for breeding high-end gift flower cultivars.   

Conclusion  

On the basis of the storage tolerance, vase life data, and associated statistical analyses of 275 cut chrysanthemum germplasm resources, a total of 7 elite germplasms with strong storage tolerance and prolonged vase life were identified. In practical breeding applications, parental materials can be selected in line with distinct breeding objectives to facilitate targeted variety development. [Ch, 4 fig. 7 tab. 47 ref.]
