| Popis: | The authors have investigated duration and period of flowering of plants (Ailanthus altissima (Mill.)) under the conditions of the right bank forest steppe and the Ukrainian steppe. We have determined that the duration and period of flowering of introduces plants to a large extent depends on the climatic conditions in which they grow. A. altissima plants are stated to belong to a group of plants with medium flowering duration. The abundance of flowering of A. altissima plants in the conditions of the right bank forest-steppe and steppe of Ukraine is estimated. The length of laying and reaching the fruits of A. altissima plants is determined to occur at different periods of the growing season, depending on the average daily temperature of the air and the place of growth of this species. We have also revealed that A. altissima trees enter the fruiting phase at the age of 10‑15 years in the southern regions of the steppe and in the 15–18 years under the conditions of the right bank forest-steppe. A. altissima during the growing season has stable flowering and fruiting in the investigated plants. The average rate of flowering abundance in the conditions of the right bank forest-steppe was stable and was estimated at 4.5, and in the steppe – 5 points. The fertility abundance index in the right bank forest-steppe and the steppe was stable and quite high – 4.0 and 5.0 points. The authors have presented the results of the study of the average parameters of the abundance of flowering and fruiting A. altissima, in green plantations growing in the National Dendrology Park "Sofiyivka" of the National Academy of Sciences of Ukraine, Uman NPC, Uman and Uman district, Dendrology Park "Veseli Bokovenki" Kirovograd region, urban area, Chethelnik Vinnitsa region, Odessa city, and Mykolayiv city. A. altissima flowering was defined to be the most noticeable in streets of Odessa and Mykolaiv (5.0 points). We evaluated plants growing in the Dendrology Park Vesely Bokoveniy, Kirovograd region as 4.5 points. Plants growing in the National Dendrology Park "Sofiyivka" of Cherkasy region were also evaluated as 4.5 points. The fruit harvesting phase in the National Dendrology Park "Sofiyivka" begins at the end of August and lasts for 35–40 days. In Odessa and Mykolaiv regions, the term of fruit reaching is much lower. The achievement phase begins at the end of July and lasts for 30–35 days, which confirms the difference in the duration of seed formation in different regions. The decorative nature of the fruits is determined by their size, shape, color, and time of reaching and falling from the plants. |
