Petrosimonieta brachiatae and Suaedeta confusae formations distributed in the territory of Azerbaijan

Abstract

Petrosimonieta brachiatae and Suaedeta confusae formations are common in a wide area of Kura-Araz plain. They are mainly distributed in salty and saline soils. Dominant of the Petrosimonieta brachiatae Formation - (Petrosimonia brachiata (Pall.) Bunge - It is an annual plant branched from the base, 5-40 cm high, first hairy, then bare. The formation is represented by 7 associations: 1) Petrosimonia brachiata; 2) Petrosimonia brachiata–Salsola dendroides; 3) Petrosimonia brachiata+Climacoptera crassa; 4) Petrosimonia brachiata+Suaeda confusa; 5) Petrosimonia brachiata-Ceratocarpus arenarius; 6) Petrosimonia brachiata-Halanthium rariphlorum; 7) Petrosimonia brachiata+Atriplex tatariica+ Salicornia europaea. Petrosimonieta brachiatae, the dominant species of the formation, is present in all groups of annual deserts. The species composition consists of 18 plants, the project cover is 40-50%. Suaeda confusa Iljin, the dominant of the Suaedeta confusae Formation, is a 10-40 (50 cm) tall, bluish, glabrous annual plant branched from the base. The formation is represented by 3 associations: a) Suaeda confusoso+Salicornia europeae; b) Suaeda confusa; c) Suaeda confusa+ Suaeda microphylla Up to 16 plants are involved in the floristic composition of the cenozoum. The total project coverage is 40-50%.
