Abstract
The main purpose of this work is to summarize the results of long-term variety testing of the intersectional hybrids obtained from controlled crosses of balsamic poplars with black and black poplars with balsamic ones. The research objectives were to study the growth, sustainability and productivity of intersectional poplar hybrids and to select the best of them. The object of research was the collection and testing site (populetum) made in 1974 on Typical Chernozem soil by stem cuttings with arrangement place 5 × 4 m in Semiluki forest nursery situated in Voronezh region. 13 clones of intersectional poplar hybrids were introduced into the test. The results of 40-year studies of their survival, height and diameter growth, trunk volume and wood stock dynamics are presented, which allowed identifying the most promising poplars’ intersectional hybrids proposed in the assortment for the creation of the most fast-growing and sustainable forest and shelter belt plantations in the region. By the age of quantitative timber maturity of intersectional poplar hybrids (i.e. 25 years) their survival was 83-100 %, and the wood stock – 462 -641 m3/ha. Further by the age of 40 their productivity and sustainability also remained quite high (survival 63-96 %, wood stock – 417-764 m3/ha).
