Abstract
The present study examines photosynthesis, photochemistry and low weight molecular antioxidants (ascorbic acid and glutathione) of two Triticum aestivum L. cultivars (H45 and Yitpi) in response to growth under two CO2 concentrations (elevated CO2, e[CO2] vs. ambient CO2, a[CO2]), two sowing times (time of sowing 1, TOS1, less stressful growing conditions vs. time of sowing 2, TOS2, more stressful growing conditions) and two water treatments (rain-fed vs. irrigated). The objective was to evaluate (1) if growth under e[CO2] will alleviate climate stresses such as higher temperature and/or limited water supply thereby reducing the need for photoprotection and concentrations of low weight molecu..
