Research of origin and bioecological features of lians

Conflicting opinions among researchers regarding the origin and some specific bioecological features of Lians are present. Results of the study of characteristic features of the growth and development of this plant group in order to clarify and compare these opinions have been showing in the paper. Separate life forms (woody, shrubby, grassy) are formed under Lians forming and light factor nutritional, humidity, and supporting factors have been played an important role in this process. It should be noted that the study of some specific bioecological features of Lianas partially solves the problem of growing them on the same territory not only with each other but also with other trees and shrubs.
