Abstract
The main target of the paper is to study structure of main pine forest types in Usmansky and Khrenovskoy pine forests, their chemical composition of essential oil (EO) monoterpene fraction. This paper is on problems of Scots Pine (Pinus sylvestris) breeding and seed-growing in the forest-steppe European part. It is done for forest culture improvement, based on genetics and breeding. The characteristic of main components of pine-needles essential oil in free and controlled cross-breeding was investigated. The established peculiarities of monoterpene biosynthesis in pine-needless essential oil are genetically motivated. The long-term opportunity for essential oil composition usage as characteristics of Pinus sylvestris breeding on resistibility to diseases and pests was defined. The structures of main forest types in Usmansky and Khrenovskoy pine forests according to basic monometric and biochemical indices were studied. The data on composition, changeability and inheritance regularity of monoterpenes may be used for recommendations on creating of Pinus sylvestris seed base on genetic and breeding bases.
