Assimilatory apparatus of pine cultures

In forest ecosystems the fir needles of coniferous trees play an important functional role, which is determined by its activity in the processes of growth and development of coniferous plant communities, interaction with other components of ecosystems and habitat. The study of the assimilation apparatus in 36-year-old pine cultures located in the cutting areas was carried out in the north-taiga district of Arkhangelsk region. Biometric and morphometric characteristics of the pine photosynthetic apparatus were studied and analyzed. It was also revealed that these conditions were favorable for the growth and development of studied artificial plantations, for the achievement of productive performance similar to the one of the pine green moss group of the middle taiga.
