Investigation of Physiological Indices of Cryptocoryne Fisch. ex Wydler in the Tropospheric Ozone
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 10
Abstract
Due to the increase in O3 gas in the troposphere layer, which is caused by industrial pollution, can cause devastating effects on crops. Contamination through this gas, causing changes in metabolic and physiological systems in plants, and thereby causing negative effects on growth and products produced. Absorption of O3, depending on plant type, condition and plant resistance is different. Ozone is a gas which its increasing in the atmosphere, causing changes on the plant such as crystals (irregular spots less than a millimeter in diameter, yellowish-brown), spots (areas of black pigment, small diameter 2-4 mm), bronzing, and reddening, is the effect of this gas can cause harmful effects on plants. Ozone impacts on aquatic plants, has not been studied much, so in this 60-day study, with Ozone 0.5 milligrams per liter against the control plant, the treatment was began and according to the results obtained, the control plants in compared with treated plants with Ozone, 0.5 milligrams per liter, have had better growth and biochemical parameters, finally, the adverse effect of ozone on these parameters, indicators were recorded.
