Popis: | The features of poplar cultivars rooting and growth are carried out. We investigated survival, growth and adaptation of poplar varieties in Podillya Region (Central part of Ukraine). Ten poplar cultivars of Ukrainian and foreign breeding were studied. These cultivars had a different intensity of growth in the conditions of Kharkiv Region. We used the following poplar varieties: 'Versiya', 'Volosystoploda', 'Constanta', 'Lvivska', 'Novoberlinska', 'Noktyurn', 'Perspectyvna', 'Rosiyska', 'Slava Ukrainy', 'Strilopodibna'. It has been revealed that environmental conditions have a considerable impact on ability of poplar varieties to root and their growth. We used following indices: the environment-varieties interaction: Wricke's ecovalence (1962), Shukla's stability variance, (1972), the ranking of genotypes to environmental resistance (Becker and Leon, 1988), the Kang's yield stability (Kang, Pham 1991). Comprehensive evaluation of availability included indicators: rooting ability, growth intensity, and adaptability to environment conditions. We determined more intensive rooting of poplar varieties: 'Lvivska', 'Novoberlinska', 'Perspectyvna' (35-39 %). The best survival of poplar varieties was in condition of maximum humidification. The less rooting activities were in drain condition (16 %). In drain condition, best survival had 'Strilopodibna' cultivar. Increase of humidification had the most intensive impact on 'Perspectyvna'. The research results have found that sufficient moisture conditions (D4) are the most appropriate ones for growing poplar. The following poplar varieties demonstrated the highest growth: 'Lvivska', 'Novoberlinska' and 'Versiya'. The highest growth in minimal humidification conditions had the following varieties: 'Volosystoploda', 'Lvivska' and 'Constanta'. According to the comprehensive assessment of the rooting ability, growing and adaptability to the environment condition, the most availability is presented by the varieties of 'Lvivska' and 'Novoberlinska'. The variety of 'Volosystoploda' is advisable to use as one of the most stable in condition of reducing moisture. |
