[IBC] humidity
Bill,
What else will your book deal with? Jerry Meislik Whitefish Montana USA Zone 4-5 http://www.bonsaihunk.8m.com/ Transpiration Transpiration is the process by which a plant loses water primarily from leaf stomata. Transpiration is a necessary process that uses about 90 percent of the water that enters the plant through the roots. Transpiration is necessary for mineral transport from the soil to the plant parts, for cooling plant parts through evaporation, to move sugars and plant chemicals, and to maintain a turgor pressure. The amount of water lost from the plant depends on several environmental factors, such as temperature, humidity and wind or air movement. As temperatures or air movement increase, transpiration increases. As humidity decreases, transpiration increases. In the winter time The plant reduces both transpiration and respiration processes. The plant still needs the water intake from other sources; such as the relative humidity from a water dish in the winter time as the stomata (this reduces transpiration) will open to increase to take in water vapor for photosynthesis needs. hope this helps, Bill Daniels In Sunny California ************************************************** ****************************** ++++Sponsored, in part, by John Quinn++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?
