Abstract:

China is one of the distribution centers of Ribes L. plants in the world. In order to reveal the characteristics of species diversity and distribution patterns of Ribes L. in China, and to explore its relationship with environmental factors, the field surveys, specimen identification and data analysis were conducted. The results showed that: (1)There were 56 species of wild Ribes L. plants in China, belonging to six subgenera: subgenus Grossularia, subgenus Ribes, subgenus Berisia, subgenus Coreosma, subgenus Hemibotrya and subgenus Grossularioides.(2)Wild Chinese Ribes L. plants were mainly distributed in the southwest, northwest and northeast regions, the northwest region had the highest species richness, with 34 species belonging to five subgenera, followed by the southwest region with four subgenera and 30 species, and the northeast region had six subgenera and 16 species. (3)The vertical distribution patterns of wild Ribes L. plants in China were remarkable, and the elevation of the concentrated distribution of Ribes L. gradually increased with the decrease of latitude. In the higher elevational northeast region, Ribes L. plants were distributed in the elevation range from 700 to 2 100 m, and concentrated in the elevation range of 700 to 1 500 m. In the middle elevation northwest region, Ribes L. plants were distributed in the elevation range of 1 000 to 3 000 m, and concentrated in the elevation range of 1 000 to 2 000 m. In the lower elevation southwest region, Ribes L. plants were distributed in the elevation range of 2 500 to 5 000 m, and concentrated in the elevation range of 2 500 to 4 000 m.(4)There were 25 endemic species of the Ribes L. in China, including 19 species in the southwest, 15 species in the northwest, none in the northeast, and three endemic species in other regions of China. The distribution of regional endemic species of the Ribes L. was obvious, with 12 species in the southwest, nine in the northwest and eight in the northeast, respectively. No common species were found in the southwest, northwest and northeast regions. In conclusion, the species composition of the Ribes L. in China showed a distinct geographic distribution pattern, the species composition varied in different regions, and this study revealed the species diversity characteristics and distribution pattern of the wild Ribes L. plants in China.
