Modification of yield scales for pine species for the conditions of the arboretum of the Mountain-Taiga Station

Abstract

In modern conditions, the problem of biodiversity conservation is very acute. The solution of this problem can be facilitated by the introduction of plants by way of increasing the species composition of plants in natural landscapes and their productivity and resistance. A network of botanical gardens and arboretums can be a source of seeds for introduced plant species at the initial stage. Therefore, the study of the dynamics of the generative development of introduced species and the actual yield of cones and seeds in specific plantings is very important. The existing forestry methods for determining the yield of conifers are hardly suitable for use in an arboretum. This article proposes the principle of modifying the existing yield scales for introduced pine species, taking into account the specific growing conditions in the arboretum. The most important of these conditions are the nature of the illumination of the crowns, the scheme of planting trees and their phytocenotic environment.
