| 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 |
