Concerning the study of the cenoflora of weed-field communities in Perm Territory and adjacent areas of the Republic of Bashkortostan

Background. An analysis of the structure of segetal communities is required to reveal the peculiarities of its formation, develop adaptive strategies for weed component management in fields, and assess and predict main trends in the changes of the species composition.

Materials and methods. A geobotanical study of segetal communities within the forest zone of Perm Territory and adjacent areas of the Republic of Bashkortostan was conducted using standard methods.

Results and conclusion. A syntaxonomic analysis helped to identify 4 phytocenons represented by communities of winter and spring cereals, tilled crops, and forage grasses. The cenoflora contains 106 species of vascular plants; 50 of them are included in the floristic core of plant communities. The richest in species within the cenoflora are winter and spring crops. Communities of tilled crops are leading in terms of species concentration, averaging 15.9 species per 100 m². Differentiating groups and a common group of species of different syntaxa were identified. It is shown that the common group of species, occurring with high constancy and abundance, represents hard-to-eradicate weeds that deserve special attention while developing a system of weed control for crop fields. A dangerous invasive species, Heracleum sosnowskyi Manden., was found in spring crop communities. Its naturalization in the fields of the studied areas presents a serious threat and requires urgent measures to control its distribution and abundance.
