B a c k g r o u n d . Global climate changes have a negative impact on the life of native plants, reducing biodiversity. But on the other hand, the increase in average annual temperature causes the natural migration of species and can make it possible to grow plants from warmer climatic zones, which are not yet widely cultivated in Ukraine. One of...
