Abstract:

Objective: The objective of this study was to determine anthocyanin components and contents in petals of Camellia japonica 'Chidan' and its bud mutation cultivars, and to clarify the material basis of their color formation by combining with phenotypic analysis of flower colors, then reveal their relationship between anthocyanin components and flower colors and provide the basis for the bud mutation breeding of flower colors in C. japonica. Method: Flower colors were measured by CIE L* a* b* scale, and anthocyanin components and contents were measured by high-performance liquid chromatography coupled with diode array detection (HPLC-DAD) and ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). The relationship between flower colors and anthocyanin components was explored by multiple liner regression analyses.Result: Seven anthocyanin components were detected in C. japonica 'Chidan' and its bud mutation cultivars, that were cyanidin-3-O-β-galactoside (Cy3Ga), cyanidin-3-O-β-glucoside (Cy3G), cyanidin-3-O-(6-O-(E)-caffeoyl)-β-galactoside (Cy3GaECaf), cyanidin-3-O-(6-O-(E)-caffeoyl)-β-glucoside (Cy3GECaf), cyanidin-3-O-(6-O-(Z)-p-coumaroyl)-β-glucoside (Cy3GZpC), cyanidin-3-O-(6-O-(E)-p-coumaroyl)-β-galactoside (Cy3GaEpC) and cyanidin-3-O-(6-O-(E)-p-coumaroyl)-β-glucoside (Cy3GEpC). Anthocyanins were not detected in petals of C. japonica 'Yudan', and Cy3GECaf were not detected in C. japonica 'Jinbi huihuang'. Objective: Flower color was intensified with the increase of the contents of main anthocyanin components and total anthocyanin of C. japonica 'Chidan'and its bud mutation cultivars. The main anthocyanin components were Cy3G and Cy3GEpC in pink and red petals, and Cy3G and Cy3Ga in dark red petals. The increase of proportions of Cy3Ga and Cy3G in petals of C. japonica 'Chidan'and its bud mutation cultivars caused intensification of the flower colors. Cy3G and Cy3GEpC were the main anthocyanins which determined the red color of petals in C. japonica 'Chidan' and its bud mutation cultivars, and the accumulation of their contents significantly intensified red color of the petals.

Key words: Camellia japonica, bud mutation, anthocyanin, flower colors, ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry
