Genetic features of the offspring of Scots pine (Pinus sylvestris L.) trees differing in the abundance of fruiting
Abstract Development of artificial reforestation is based on selection and genetics. Solving issues related to stability and productivity improvement of cultivated forest-forming species is impossible without taking into account the hereditary properties of the tree offspring. Genetic features of th...
