Abstract

This article presents the results of research of the effect of treatments of seed and planting material of Scots pine (Pinus sylvestris L.) with growth regulators and fungicides. The experiments were carried out in open ground in 2020 on the territory of the permanent nursery of the State Forestry Institution “Logoisk forestry”. Before sowing, some of the seeds belonging to the first quality class were encrusted with a protective and stimulating composition, including the growth regulator Ecosil Mix and the fungicide Vincit Forte. In parallel, on the 30th and 60th days, solutions of Ecosil Mix or Ecosil Plus were introduced by spraying vegetative plants in several variants. Seedlings were grown in field conditions for 90 days, after were measured morphobiometric as well physiological and biochemical parameters.

As a result, it was found that treatments with the Vincit Forte, as well Ecosil Mix and Ecosil Plus, have a significant effect on parameters of Scots pine seedlings. The dependence can be traced both on the combination of drugs and on the frequency of foliar treatments. The greatest growth-stimulating effect is observed when vegetating plants are sprayed with Ecosil and seeds of Ecosil Mix and Vincita Forte. The activation of seedling growth was accompanied by a noticeable improvement in photosynthetic and oxidative processes, as well an increase in the integrity of plant cell membranes.
