以地被菊品种‘紫重楼’为试材,对‘紫重楼’花发育过程中CmUFGT基因相对表达量、可溶性糖含量及花色苷含量的变化规律进行了初步的探究讨论。结果表明:‘紫重楼’叶片中可溶性糖含量随着花朵发育呈先升后降趋势;‘紫重楼’花发育过程中舌状花可溶性糖含量、花色苷含量和CmUFGT相对表达量均呈先升后降趋势,但可溶性糖含量峰值滞后;花发育过程中子房中花色苷含量总体比较平稳,后期略有下降,可溶性糖含量和CmUFGT相对表达量呈上升趋势;同一头状花序不同轮舌状花花色苷含量从外到内呈上升趋势,CmUFGT相对表达量呈先升后降趋势,可溶性糖含量呈下降趋势。
The experiment was carried out to investigate the variation of relative expression of CmUFGT gene, soluble sugar content and anthocyanin content during the flower development of ’Zilv floor’ with the ground-tolerant Chrysanthemum variety Zizhonglou. The results showed that the content of soluble sugar in the leaves of Zizhonglou rose first and then decreased with the development of flowers. The soluble sugar content, anthocyanin content and the relative expression of CmUFGT in the flower of Zizi Lou The peak of soluble sugar content lags behind; the content of anthocyanin in ovary in the flower development process is generally stable and slightly decreases in the late stage, while the soluble sugar content and the relative expression level of CmUFGT are on the rise; the same flower head with different rounds The content of anthocyanin in tongue-shaped flowers increased from the outside to the inside, the relative expression of CmUFGT increased first and then decreased, and the soluble sugar content showed a downward trend.
