Bioecofunge-C preparation impact on growth and development of pine planting material (Pinus sylvestris L.)

Abstract

Pine plantations drying has been observed during the last decade. Mass drying occurs in the temperate climate zone forests. Scots pine has been signifcantly weakened in recent years, which may further result in a change in the type of forests in Zhytomyr Polissia. This article covers the issue of growing Scots pine seedlings treated with Bioecofunge-C. A study of the biological preparation effect on the germination and growth of Scots pine seedlings in the conditions of Zhytomyr Polissia was conducted. It was proved that the germination energy of Scots pine seeds was signifcantly higher in the areas where Bioecofunge-C was applied compared to the control and amounted to 95 %. An average increase in the height of the seedlings by 34.2 % and root length by 34.9 % was noted during the cultivation of one-year-old Scots pine seedlings in the forest nursery of the Korbutiv Forestry, where the seeds were treated with the preparate. Scots pine seedlings were treated (root dosing) during the growth and development of Scots pine seedlings. The obtained results showed positive dynamics in terms of height in comparison with the control treated with water. The preparate use is promising for obtaining high-quality planting material since the treatment with Bioecofunge-C ensure the preservation, obtaining high-quality planting material and the yield of seedlings. It has been established that obtaining high-quality planting material is one of the most important components of the technologies for growing tree and shrub plants at forestry enterprises of Ukraine. However, obtaining and high-quality planting material resistant to adverse factors requires improvement of existing or development of new measures and methods. It has been proven that the artifcial restoration of the Zhytomyr Polissia forests depends on the cultivation of high-quality planting material.
