Scottal pine seed productivity under different climatic and ecological conditions

The article analyzes the parameters of seed productivity of Scots pine growing in different environmental conditions. The analysis was carried out in years with normal climatic conditions and in drought conditions. It was found that in the studied populations the number of seeds in a cone in most trees increased under drought conditions. However, the full-grain content of seeds in this period in both populations decreased significantly. This means that the arid conditions negatively affected the reproductive cycle of the pine and, despite the high number of seeds in the cones, the empty seeds increased sharply.
