Structural and functional properties of the male generative organs of Siberian larch and scotch pine in the conditions of climate change in Siberia

The influence of air temperature on the male generative organ state of Siberian larch and Scotch pine in the autumn-winter period is considered in the article. In the course of these studies the time offset of the male generative organ development of these conifer types in abnormal years with long and warm autumn in Krasnoyarsk city and its surroundings that leads to the sterile pollen formation and cone and seed productivity decrease is determined.
