Age dynamics of growth separate families of a hybrid-seed plantation pines ordinary in various forest growth areas

Abstract

In this work the age dynamics of families growth of hybrid-seed plantations of Pinussylvestris in test cultures of different ages, created inNemansko-Predpolessky and Berezinsko-Predpolessky forest growing areas is studied. It is established that the seed-bearing breed of hybrid-seed plantations of Pinussylvestrisis characterized by the intensive height growth and preserves the inherent high growth energy over a period of 10-year tests.
