The experiment was performed to elucidate the effect of simulated acid rain on growth of the seven crops(Daucus carota var. saliva DC., Fagopyrum esculentum Moench, Brassica campestris subsp. napus var. pekinensis Makino, Raphanus sativus var. hortensis for. acanthiformis Makino, Brassica alboglabra Bailey, Caphsicum annum 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 with each crop was influenced from simulated acid 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 gradients. According to acidity, total DNA contents of each crop was showed a definite reduction. In conclusion, plant growth was stimulated decreasingly and the changes of total protein patterns and DNA contents extracted from leaves trended with simulated acid rain was showed seriously.
