Abstract
Hanan Mohamed Abd El-Gelil. Mutagenic effect of current application of pesticides on some cotton varieties. Unpublished. M.Sc. Thesis, Department of Genetics, Faculty of Agriculture Ain Shams Unive1•isty.
The Probable mutagenicity of pyrethroid and catabron insecticides usmg six long staple cotton varieties (Giza 75, Giza 80, Giza 83, Giza 85, Giza 86 and Dandera).
The study involved their effect on mitotic division in root tips, the pwcess of
meioses in cotton flower buds and on the storage protein of theM:; cotton seeds and the st orage of the cotton leafs
The different concentrations of the two insecticides induced significant
decrease in of mitoses. The results also indicated that the two pesticid•:!S have mutagenic activity at the Cytological level in the six cotton varieties. All doses were elfcctive in inducing chromosomal abnormalities a nd a clear dose response relationship was observed in the various cytological testes.
Analysis of chromoso mal abnormalities revealed tha t the two insecticides display clastogenic and turbagen i c activities.
At the protein l evel pyrethroid and cat abron were found to play a n.:!
impontant role in changi ng the protei n banding patterns in seeds and leafs of si x cotton variet i es.
C hanges in protein band intensit y were record ed as compared with the control. The results obtained in the present st ud y suggest possible mutagei nc potential of the t wo pesticid es.
