Anatomical structure of the stem and drought resistance of Aylostera flavistyla, Mammillaria bocasana and Echinocactus grusonii

Abstract

The anatomy of Aylostera flavistyla, Mammillaria bocasana and Echinocactus grusonii stems was studied. Different trends of plants’ adaptation to condition of water deficit were identified. It was shown that the most drought-resistant plant is E. grusonii, and the less drought-tolerant is M. bocasana.
