CHARACTERISTICS OF PINUS SYLVESTRIS L. SEEDS UNDER DROUGHT CONDITIONS IN THE STEPPE REGION OF THE CENTRAL CHERNOZEM REGION
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%.
