| Popis: | We investigated poplar varieties of Ukrainian and foreign selection in Vinnytsia region (central part of Ukraine). This poplar species had a different growth and productivity on poplar tree archives in Kharkiv region (west part of Ukraine). Poplar selected species investigated in Vinnytsia are as follows: Versiya, Volosystoploda, Constanta, Lvivska, Novoberlinska, Noktyurn, Perspectyvna, Rosiyska, Slava Ukrainy, Strilopodibna. We used Terra-Vet-100, a substance for moisture accumulation, for investigation of impact this substance on survival and growth of poplar tree during the first vegetation year. The poplar experiment was carried out using creation of four poplar plantation of selected species in various conditions (soil and moisture composition). Three experimental plots were after clear-cut of ach and pine tree stands. Only one plot was presented area after agricultural using. We used Tera-Vet-100 on three plantations with poor moisture. Poplar shoots were treated with Tera-Vet-100 before planting. The best survival and growth where observed in condition of higher moisture level (22 %). The best rooting process (16-20 %) was determined after using of Terra-Vet-100 for following selected species: Novoberlinska, Volosystoploda, Constanta, Perspectyvna in condition of medium moisture and fertile soils. Such poplar varieties as Versiya and Slava Ukrainy showed poor rooting process. The following selected species had high level of productivity during the first vegetation year: Volosystoploda, Lvivska. Such poplar selected species as Novoberlinska, Perspectyvna, Volosystoploda showed positive reaction after using of Terra-Vet-100. We have determined that selected polar species such as Lvivska, Novoberlinska and Volosystoploda have the best survival, productivity and adaptability in condition of Vinnytsya region. As a result of investigation, we recommended this species for using in forestry and agricultural practice in central part of Ukraine. But this is only previous results after first year of investigation. Consequently, the main conclusion can be made after next 2-3 year of investigation of this species in different environment condition. |
