The carotinoids content in the acerose leaves of the Pinus sylverstris L. geographical crops in the conditions of the Minusinsk forest farm (Krasnoyarskii krai)

The article is dedicated to the study of the variability of the carotinoids content in the acerose leaves of different geographical archangel fir populations that grow in the conditions of the Minusinsk forest farm (the south forest steppe of the Middle Siberia). The highest indices of carotinoids are for climate types from neighboring regions with similar natural and climatic conditions. The carotinoids content decreases to the north.
