Abstract
An experimental study to evaluate the growth and development of five hybrid forms of poplars at the early stage of vegetation was carried out under indoor conditions. In the course of the research, morphometric traits were measured: shoot height, stem diameter at the base and leaf plate area. Reliable differences between hybrids were established, correlations between biometric parameters were identified and cluster analysis was performed. The results obtained allowed us to identify hybrids with the most pronounced productivity traits and to preliminarily assess their photosynthetic and carbon storage potential.
