Participation of Species of the Family Brassicaceae Burnett in Spring Phytocenosis of the Lowland Zone of the Nakhchivan Autonomous Republic

The spring flora of the lowland part of the Nakhchivan Autonomous Republic was studied. The role of representatives of the family Brassicaceae Burnett in the spring flora was determined. The phytocenosis, including representatives of the family Brassicaceae Burnett, consists of 15 perennial species (41.66%), 13 annual species (36.11%), 3 biennial species (8.33%), one species that is either annual or biennial (2.77%), and among the woody representatives, one species (2.77%) is a tree and 3 species (8.33%) are shrubs. By ecological group, 17 species (47.22%) are mesophytes, 12 species (33.33%) are xerophytes, 3 species (8.33%) are xeromesophytes, 2 species (5.55%) are mesoxerophytes, 1 species (2.77%) is a hydromesophyte, and 1 species (2.77%) is a hydrophyte. Perennials predominate by life form, and mesophytes predominate by ecological group. The plants that form the phytocenosis mainly belong to the family Asteraceae Bercht. & J.Presl (12 species - 33%). The coordinates of the site where the phytocenosis with representatives of the family Brassicaceae Burnett is located in the lowland zone of the Autonomous Republic were identified using GPS: 39º4'49.73952'' N, 45º33'56.19276'' E, 956 m above sea level. Other significant representatives of the spring flora of the lowland part of the Autonomous Republic are also present here.
