Abstract

Abstract:

To investigate the effects of hydrogen-rich water (HRW) at different concentrations on the growth of potted China rose (Rosa chinensis), growth indicators such as leaf length, leaf width, bud number, and maximum flower diameter were measured. The results revealed that all HRW concentrations promoted the growth of potted Chinese roses, improved plant architecture, and the 100% HRW treatment exhibited more pronounced enhancement. HRW treatments improved leaf traits and photosynthetic characteristics by increasing leaf length, leaf width, leaf number per plant, and relative chlorophyll content, with the 100% HRW treatment showing higher increments. Additionally, HRW regulated floral development: both 50% and 100% HRW increased flower quantity, optimized flower morphology, and extended single-flower longevity, thereby enhancing ornamental value. In conclusion, HRW improves the ornamental and economic value of Chinese roses by optimizing plant architecture, enhancing leaf traits and photosynthetic efficiency, increasing flower number, regulating floral morphology, and prolonging flowering duration.

Key words: hydrogen-rich water (HRW), China rose, growth morphology, flower traits, ornamental value, economic value
