The experiment was performed to elucidate the effect of simulated acrid rain on growth of the seven crops(caucus carota vu sativa DC. , Fagopyrum esculenkm Moench, Brassica cmpespis subsp. napus var. pekinensis Makino , Raphuus satlws vu. hortensis for. acnMormis Makino, Brassica dbogjabra Bailey, Caphslcum mum L., and Perilla frutescens Britton). The pH levels of simulated acid rain ranged pH 3.1, 3.6, 4.1, 4.6, 5.1 and 5.6. The germination 10 each crop was influenced from stimulated acrid rain except buckwheat and kale. A general decrease of growth in crops was observed with Increasing pH concentrations. The pattern of soluble protein was observed a tendency to decrease from acidic pH eradlents. According to acidity, total DNA contents of each crop was showed a definite reduction. In conclusion, plant growth was stimulated decreasln and the chanties of total Protein Patterns and BNA contents extracted from leaves trended with stimulated acrid rain was showed seriously.
