Изменчивость длины трахеид сосны обыкновенной в зависимости от лесотипологических условий

The article provides a comparative analysis of the lengths of early and late tracheids of dominant coeval Scots pine trees. It has been established that tracheids of juvenile wood are characterized by significant differences in length and the difference between them reached 400%, while in the zone of mature wood, the length of both early and late tracheids stabilizes, demonstrating small fluctuations (in within 10%). That makes it possible to use the obtained results to assess forest typological variations. It was shown that the longest tracheids were found in sorrel pine forests, and the shortest – in sphagnum; ericetal pine forests showed intermediate results. The idea of significant differences between the lengths of tracheids in the zone of mature wood of model trees of 3 trial plots is substantiated.
