Abstract:

Salsola (L.) is one of the biggest genera in the family Chenopodiaceae and plays an important role in the flora and plant resources utilization in Xinjiang. In this study, the biodiversity (including fruiting perianths and leaf anatomical structures) and geographical distribution of 32 Salsola species distributed in Xinjiang were observed. The results were as follows:  = 1 \* GB3 According to the fruiting perianths with or without the winglike appendages, they were divided into two kinds, and the kind with winglike appendages had more abundant forms; = 2 \* GB3 There were four leaf anatomical structures including C3-SYMP, C3-C4, C4-SALS+H, and C4-SALS-H. Based on these structures, the most Salsola species in Xinjiang were C4 plants; = 3 \* GB3 The Salsola species in Xinjiang were mostly herbaceous, and their habitats were mainly in dry and salty environments; = 4 \* GB3 They were distributed in six geographical areas in Xinjiang, and the most ones were distributed in the Juggar subregion, and then in the Tacheng-Yili subregion; = 5 \* GB3 The common Salsola species in Xinjiang and the neighboring countries were significantly more than those in the neighboring regions of China.
