Ecological bases of seed zoning of woody plants

Based on the study of the dependence of yield and the quality of seeds of a variety of plant species on natural conditions, theoretical and practical provisions for the zonal seed-growing of forest tree plants are established. The regularities in variability of yields and quality of seeds of woody plants are determined depending on soil and climatic conditions, which made it possible to offer a fundamentally new classification of the crop when evaluating it as a seed material: Type I - high yield with high seeding properties of seeds; II type - high yield with low seeding properties of seeds; III type - low yield with high seeding properties of seeds; IV type - low yield with low seeding properties of seeds. Each of these types of crops is formed in certain soil-climatic conditions. On the basis of detailed studies of various aspects of the ecology of seeds, the corresponding soil-climatic zonality of seed-growing of forest plants is determined: Zone of optimal seed production (type I of the crop); Zone of risky seed production (type II crop); Zone of permissible seed production (type III crop); Zone of inadmissible seed production (type IV crop). The procurement of raw materials and seeds of woody plants should be concentrated in the areas of optimal seed production. In areas of acceptable seed production, it is necessary to carry out measures to increase yields. In the second and fourth zones, seed production is not advisable. The methodological basis of forest seed zoning is the allocation of territories where populations of a certain genotypic composition have been formed in the course of evolution. The developed ecological bases of seed production are the further development of the currently functioning system of forest seed zoning, based on the division of the country's territory into forest seed areas, where populations of a certain genotypic composition were formed during the evolution.
