Abstract:
Environmental stresses or abiotic stresses especially water usually gives many impact for
plant growth and productivity. Water deficit has profound impact on ecological and
agricultural systems by causing oxidative stress. By relating this environment perturbation
with plants tolerance, resistance of plants towards stresses can be identified and improved
the plants productivity. The objectives of this study are to determine the effects of water
deficit on the growth and chlorophyll content of Zea mays. Zea mays were treated with
different volumes of water i.e. 0, 20, 40, 60, 80 and 100 ml. The growth and chlorophyll
content were determined at 0, 1, 2, 3, 5, 7 and 11 days of treatment periods. In general, total
chlorophyll content increased at early stages but prolonged exposure to water deficit
resulted in the reduction of chlorophyll content. For growth of Zea mays, there were no
significant differences observed between treated and untreated plants. These results
indicated that water deficit did not significantly affected the growth and chlorophyll
content of Zea mays leaves.
