Growth of Scots pine (Pinus sylvestris L.) provenances in conditions of Low Dnieper region
Journal Title: Лісівництво і агролісомеліорація - Year 2014, Vol 124, Issue
Abstract
The article is regarded the growth of Scots pine ecotypes in provenance test that was create in 1963 year in conditions of low Dnieper sands. 11 ecotypes from different regions of Ukraine in two replications are represented in the cultures. The average preservation of the ecotypes’ trees at 50 years of age is 12,2 %. It was found that the trend of worst growth for Polissya ecotypes and better growth for ecotipes from steppes of Ukraine had been noted for 40 years. During selection evaluation of the variant prospects under test conditions the productivity index (timber volume per 1 ha) should be used limitedly. Further observations are needed for the growth and resistance estimation of ecotypes and for studying the possibility of viable self-seeding production.
