Abstract

Monitoring the state of forest stands is an urgent task for researchers in modern environmental conditions. Scots pine is one of the main forest-forming species in the world. The article studies the quality indicators of the seeds of a pine growing in the steppe zone against the background of a spring-summer drought. The objects of research are in contrasting environmental conditions. It was found that in the studied plantations there is a very high level of empty seeds: 10-12 seeds per cone. In a plantation from an ecologically clean territory, graininess is 4.7% higher than in a plantation with anthropogenic impact. Experimental data on soil germination showed that pine seeds of the steppe region, collected under arid conditions, are absolutely not viable, germination is 0%.
