Abstract
This study examined the possible use of wastewater from different
sources for irrigation purposes. Study of cytotoxicity and genotoxicity of
these types of water, was carried out using Vicia faba L. as a test plant.
Plants were treated with different types of water (Distilled water as a
negative control, aqueous hydrogen peroxide as a positive control mutagen,
tap water, agricultural drainage water and mixed water). Most of growth
parameters were significance affected by pollution which is clearly reduce
most of parameters studied as germination index, root length, seedling vigor
index, tolerance index and plant height. On the other hand, induction of
morphological abnormalities in root was observed. Polluted water treatments
were also affected mitotic and meiotic parameters. Such effect was clearly
observed in decrease the frequency of mitotic index, phase frequency and
increase in the percentage of chromosomal aberrations in mitotic and
meiotic chromosomes of V. faba. Molecular analysis for the offspring seeds
of V. faba for protein, isozymes and RAPD profiles showed that polluted
water had genotoxic effect on Vicia faba plants.
