Chapter 7 - Hydrology and Plant Water Relations

摘要: Publisher Summary Water is a controlling factor in the growth of forests, indeed, forests do not occur low rainfall regions world. The water balance stands depends on precipitation, interception, run-off, evaporation and drainage with exception precipitation all these processes are strongly influenced by tree populations, stand structure, canopy architecture. availability soil at any time, interacting evaporative demand atmosphere hydraulic capacity trees, determines conductance ability trees to absorb CO 2 for photosynthesis. Tree–water relations an excellent well-documented example different levels response times. hydrology forest ecosystems important only because interactions between but also importance catchments as supply systems. first part this chapter provides outline hydrological its components, including consideration root zones movement soils. Then it considers tree–water concludes brief discussion consequences stress.
