|Title:||Effect of elevated carbon dioxide on Spinach (Spinacia oleracea L.) plants|

|Abstract:||Spinach is an important leafy vegetable enriched in iron. An experiment was conducted to study the effect of elevated carbon dioxide on growth and nutrient composition of spinach. The plants were grown in open top chambers (OTC) under two concentration of carbon dioxide viz. ambient (ACO2, 350± 50 μmol mol-1) and elevated (ECO2, 600± 50 μmol mol-1) and were analyzed 40, 60 and 80 days after exposure to CO2. The plants grown in ECO2 had higher net photosynthetic rate and lower stomatal conductance when compared with the plants grown in ACO2. ECO2 also changed the nutrient composition of leaves. Lower nitrogen and iron content and higher carbon and calcium content were observed in the plants exposed to elevated CO2. The rising CO2 may lead to changes in nutritional quality of this important leafy vegetable|
