Abstract: The characteristics of ornamentation and photosynthesis, chlorophyll fluorescence parameters in spring, summer and fallwere compared between the female (Lonicera tragophylla Hemsl. ) , male (Lonicerasem pervirens L. ) parents and their hybrid (Lonicera tellm ann iana Hort. Sp¾ th) , and the purpose of this study was to improve the ornamental effect of Lonicera by comparing the ornamental and photosynthetic characteristics of three species. The results showed that longer bloom period and more inflorescence numbers per plant were the most significant performance in hybrid; Three species had no significant difference in the maximum quantum yield of photosystem Ⅱ ( F_v /F_m ). The male parent almost had same photosynthetic rate,actual quantum yield of photosystemⅡ, p lant height, number of leaves, basal diameter and underground biomass as the hybrid. Except for F_v /F_m , all parameters of the female parent were significantly lower than those of the male parent and hybrid, revealing that it had the weakest growth vigor. The hybrid had the significant performance mainly in the total leaf area and ornamental effect. It is concluded that higher total leaf area increases the total photosynthetic capacity, which keeps the hybrid to show better ornamental effect thanits parents. Therefore, we suggest that increasing the total leaf area during the early growth stage would have a positive impact on imp roving the ornamental effect of Lonicera
