Effects of Acid Rain on the Developmental Stages of Ovules and Seed Proteins in Bean Plants (Phaseolus vulgaris L.)

Abdolkarim Chehregani and Farideh Kavianpour

Abstract:
The aim of this research was to detect some microscopic effects of acid rain on ovule formation, development, structure and protein content in plants. Bean plants were grown in plots in different groups and treated by different acid solutions of HNO3, H2SO4 and both HNO3, H2SO4. The pH of each group regulated at 2, 3, 4, 4.5. Treatments were taken for 4 weeks, one in each day. Developmental stages of ovules were compared in acid treated and control plants. Results showed that developmental process of ovules show some abnormalities. Embryo sac was not completed its growth and was smaller in the treated plants than control ones. In treated plants, vesiculation of embryo sac and plasmolysis of nucellar tissue were seen. Accumulation of dark particles and disruption of nuclear envelope in embryonic cells are the results of acid treatments. Treatments by HNO3 with pH 2, was more effective than other acid solutions. SDS-PAGE showed that protein pattern was the same in experimental and control plants but quantity of protein bands was different.
