Studying of parameters of the photosynthetic plants activities in dependence from vertical zonation

Studied the quantitative and fluorescent characteristics of photosynthetic pigmental complex of Betula pendula Roth leaves and Betula litwinowii Doluch, growing at the heights of minus 28 and plus 1800 m above sea level. Decrease of the maintenance of chlorophyll a on high-rise profile is revealed, that we connect with intensive insolation in mountains, their destruction in extreme environment. The increase in the maintenance of carotenoids on a high-rise gradient is noted.
