На основании данных о росте по высоте различных пород хвойных насаждений: сосны обыкновенной (Pinus sylvestris L.), сосны черной (Pinus nigra J.F.Arnold), ели обыкновенной (Picea abies (L.) H. Karst.) и пихты белой (Abies alba Mill.) – изучена скорость (или, темп) их роста в одном и том же возрастном интервале. Предложены новые коэффициенты для оценки типа роста и доказана их пригодность к использованию, для чего их сопоставили с нулевыми натуральными показателями Духовникова для отдельных кривых с высокой степенью корреляции. Далее путем применения новых коэффициентов по типу роста были установлены значения и интервалы показателей скорости роста насаждений исследуемых пород. Коэффициенты типа роста, как и индексы темпа роста, являются достаточно удобным инструментом для установления различий и сходства в скорости роста и типе насаждений.
