It was found from more than 20-year lasting monitoring of the hydrologic cycle in 20 mountainous sites in the Czech Republic (altitude 600–1400 m a.s.l., vegetation season April–September: mean air temperature 8–10ºC, mean precipitation total 400–700 mm, mean duration of sunshine 1100–1300 hours, and mean potential transpiration 200–250 mm) that plant temperature does not get over about 25ºC when plants transpire. According to the natural selection hypothesis, the phytocenosis able to survive the unfavourable conditions and produce the biggest amount of phytomass will be prevailing on the site occurring in the long-term stable natural conditions. Simulation of the phytomass productivity based on the optimum temperature for plant growth manifested that plants with the optimum temperature of about 25ºC can survive the unfavourable conditions and produce the biggest amount of phytomass in the studied site in the long-term scale.
