Some ecological features of Tulipa patens Agardh ex Schult. & Schult. fil. in the collection of Central Siberian Botanical Garden of Siberian Branch of the Russian Academy of Sciences

The paper analyzes the characteristics of the seasonal development of Tulipa patens from two donor regions (Altai Krai, Republic of Kazakhstan) in the ex situ conditions of the recipient region, provides comparative in situ morphometric characteristics of these two groups of plants and a comparison with plants in situ. The following characteristics of the adaptation process, which distinguish the two groups from each other growing at the time of the experiment under the same ecological conditions, were revealed: 1) the Kazakhstan plants start the growing season 2–6 days before the Altai Krai plants and most of its phases have a longer duration; 2) for Kazakhstan plants, at the beginning of the regrowth and sprouting phenophase, less sums of temperatures above zero and the number of sunny days are needed; 3) there are significant morphometric differences between Kazakhstan and Altai Krai plants, in ex situ and in situ. Republic of Kazakhstan plants that grow on rocky steppes have more adaptive potential than Altai Krai plants that grow on rocky slopes. Based on the obtained results we can assume that plants of the species Tulipa patens have genetic polymorphisms.
