Effect of Elevated Carbon Dioxide Concentration on the Stomatal Parameters of Rice Cultivars

The response of stomatal parameters of four rice cultivars to atmospheric elevated CO2 concentration (EC) was studied using open top chambers. EC brought about reduction in stomatal conductance and increase in stomatal index, size of stomatal guard cells, stroma, and epidermal cells. Such acclimation helped the regulation of photosynthesis to EC. These changes in stomatal characters made rice cultivars adjustable to EC environment.

Additional key words: epidermal cell size and density; leaf area and dry mass; net photosynthetic rate; open top chamber; Oryza sativa; stomatal size and density; stomatal conductance; stroma
