摘要

Present study showed the photosynthetic characteristics of 4 wild oil peony (Paeonia, Ranunculaceae) species from 11 provenances in different provinces in China and hereby predicted the seed yields of them. By investigating the leaf gas-exchange factors, light-response curves and Chlorophyll contents of the different peonies in April, 2015, several photosynthetic parameters were analyzed and compared. The daily photosynthesis variation curves of eight origins were bimodal while the rest three were unimodal. Results showed that Paeonia rockii from Lintao county and Paeonia delavayi from Wenbishan mountain had significantly higher net photosynthetic rate than the others, suggesting larger photosynthesis capacity. The analysis of net photosynthetic rate reduction showed that Paeonia rockii and Paeonia delavayi had larger photosynthetic abilities than the other two species. Paeonia rockii from Baokang county had the biggest apparent quantum yield and lowest light compensation point of the all, which enabled it to possess the largest radiation use efficiency and shade-endurance. Paeonia delavayi from Wenbishan mountain had the biggest light-saturated net photosynthetic rate coming with the largest photosynthesis potential. Furthermore, the total chlorophyll content comparison showed strong photosynthesis capacity in Paeonia rockii from Baokang county and Paeonia rockii from Lintao county. In summary, Paeonia rockii and Paeonia delavayi especially Paeonia rockii from Lintao county, Paeonia rockii from Baokang county, and Paeonia delavayi from Wenbishan mountain had advantages in photosynthetic capacity to synthesis organic matters and could be screened as superior provenances.
