Effect of ethanol on germination and some anatomy of Phaseolous vulgaris L

Effect of different concentration of ethanol was tested on seed germination and anatomy of leaves and stems of Phaseolous vulgaris. It was shown high concentration of ethanol decreased germination of seeds. Stomatal frequency, stomatal index, lengths and widths of cells was measured after spraying leaves with water and seven different concentrations of ethanol. The highest length of epidermal cells on upper surface of leaf was seen in 10% ethanol treatment. Addition of ethanol reduces stomatal frequency on upper surface of leaf. The highest amount of stomatal index on upper and lower surface of leaf was seen in 80% ethanol treatment. Addition of ethanol reduces frequency and length of trichomes on upper surface of leaf but have not significant effects on length of young vessels.
