EFFECT OF AIR TEMPERATURE ON LEAF PHOTOSYNTHESIS IN ELDER
Journal Title: Current Trends in Natural Sciences - Year 2012, Vol 1, Issue 2
Abstract
Temperature with solar radiation intensity is the main external factor affecting photosynthesis process. Measurements were collected in the 2011 growing season. Photosynthesis and respiration measurements were made at Sambucus nigra leaves with a CO2 analyzer. The aim was to develop a model of photosynthesis in relation to temperature (which is in close relationship with air humidity). Photosynthesis of Sambucus nigra leaves is sensitive to temperature with an optimum around 25-28oC and rates declining by 18% with air temperature around 33-35oC.
