Based on the fact that more than half of the studied plants are polyploid, M.S. Navashin was one of the first to show that polyploid forms can appear in response to factors of adverse conditions, and that plants changed as a result of such polyploidization are more adaptable to adverse conditions and have a stronger ability to spread. showed.
