Abstract
The meiotic effects of 2, 4-D and 2, 4, 5-T on hexaploid wheat T. aestivum L., tetraploid wheat T. durum Desf. and a diploid related species Ae. ligustica L. The two herbicides increased the percentages of abnormal meiotic cells significantly. The kinds of irregularities observed were lagging chromosomes, single and multiple bridges, fragments and asynchoronization in the disjunction of chromosomes during second anaphase. It was evident that chromosomal stickiness was the cause of most of the aberrations observed. The increase in dose of 2, 4, 5-T caused significant increase in the percentages of meiotic cells with chromosomal aberrations in Ae. ligustica L.
