Abstract

Abstract:

In this study, Zhangzhou narcissus was used as the test material, purified water (CK) was used as the control, and two treatments of 50% and 100% hydrogen-rich water (HRW) were set up to preliminarily reveal the effects of different concentrations of HRW on the growth of narcissus by comparing the differences in the indexes of narcissus flowering period, leaf length, and the number of flowers in each period. The results showed that different concentrations of HRW significantly prolonged the flowering period of narcissus, and the prolongation time of 100% HRW was significantly greater than that of 50% HRW. Both 50% and 100% HRW enhanced the leaf length and scape height of narcissus at the late stage, and 100% HRW significantly increased the SPAD of narcissus leaves at 14 days after flowering, and prolonged the greening period of narcissus leaves. Under the treatment of 100% HRW, narcissus leaves still maintained a high level of nitrogen content at 14 days after flowering. HRW significantly increased the number and proportion of flowers in the blooming stage of narcissus and decreased the number and proportion of flowers in the senescence stage of narcissus at 14 days after flowering. By analyzing the correlation of various growth indicators of narcissus, result showed that maintaining a higher level of leaf nitrogen content was the key to prolonging the flowering period of narcissus. In summary, HRW can significantly prolong the ornamental time and increase the ornamental value of narcissus by maintaining a higher level of leaf nitrogen content.

Key words: hydrogen-rich water (HRW), narcissus, flowering period, leaf, scape, nitrogen content, delaying senescence, ornamental value
