HEAT AND DROUGHT RESISTANCE OF THE IRON TREE INTRODUCED TO THE ABSHERON PENINSULA OF AZERBAIJAN

The iron tree is one of the relic plants of the Caucasus, in particular in Azerbaijan. The plants are over 4000 years old. Homeland is Persia, modern Iran. It is the rarest plant common on the slopes of the Talysh Mountains in the Lankaran region of Azerbaijan. The plant belongs to the family Hamamelidaceae, genus Parrotia , and species Parrotia persica (D. C.) C.A. May. The tree has the highest growth and development, durability and the ability to naturally regenerate, high-quality wood, which differs from all types of tree species in specific gravity. Therefore, the wood of this type is dense and sinks in water. This quality of wood allows it to be widely used in the manufacture of furniture, construction and in the manufacture of equipment for underwater and sailing shipbuilding. For the first time in the conditions of the dry subtropical climate of Absheron in Azerbaijan, 10 specimens of young iron tree seedlings were introduced, delivered from the Lankaran Scientific Center of ANAS. The seedlings were planted at the experimental site of the Institute of Dendrology of ANAS in early spring. The purpose of this article is devoted to an experimental study of heat resistance and drought resistance, in connection with the dynamics of photosynthetic activity of this species introduced in the conditions of the Absheron Peninsula of Azerbaijan.
