During the last two centuries global climate, change has been.Primarily attributed to elevated atmospheric carbon dioxide.(CO2) concentrations and increased surface temperatures (Xu.Et al. 2013). Although the concentration of atmospheric CO2.Has already increased from 280 lmolmol1 to more than.390 lmolmol1.It is, anticipated to reach 700 lmolmol1 by.The end of the 21st century (IPCC 2007). Additionally compared,,With the end of the last century the surface, temperature.Will increase by 1.1 - 6.4 ° C on average by the end of the current.Century. Commercial growers throughout the world use supplemental.CO2 in their greenhouses to enhance agricultural.Yields and improve the quality of their crops which also, experience.Heat stress especially in, the summer (Li et al. 2013).Changes in these environmental factors will likely lead to plant.Exposure to both elevated temperatures and higher, CO2 levelsWhich may have interactive effects on plant growth (Yu et al.2014). Under natural conditions vegetable crops, eventually.Face episodes of heat stress that result in a loss of yield and.Loss of agricultural produce quality. The individual effects of.Eelevated CO2 and high temperature have been extensively documented;However their combined, effects on plants are relatively.Less known (Xu et al. 2013).
