Abstract

Deserts of cold are related more to the physiographic causes because of their location and are characterized by natural stress conditions such as high altitude, aspect, subzero winter temperature (-20o to -30oC), high daily and seasonal diurnal temperature variations, high IR and UV radiations, reduced O2 and CO2 levels, soil moisture frozen during early spring, etc., which hinder the photosynthetic activities. Under such stress conditions, only few species possess the capability to survive. The study deals with the estimation of the photosynthetic rate, transpiration rate and water use efficiency of natural flora and the introduced species.
