CYTOGENETIC EFFECTS OF ALDRIN ON SOME SPECIES OF LENS AND PISUM | BIONATURE

Through root-tip, seed-soak, and spray treatments, the cytogenetic effects of Aldrin (1,2,3,4,10,10-hexachloro-1,4,4a,5,8,8a hexahydro1,4,5,8 endo exo di methano naphthalene) were investigated in Lens culinaris, L. esculenta, Pisum satiuum, and Pisum arvense. Inactivation of the spindle mechanism, chromosome condensation, and chromatin bridge are examples of somatic chromosomal abnormalities. Multivalents (quadrioctavalents), fragments, and chromatin bridges were discovered in meiosis sticky chromosomes during anaphase I. Mitosis and meiosis were almost typical in the M2 generation. Spray treatment increased plant height in the M1 generation, whereas seed-soak treatment decreased plant height. Both the seed-soak treatment and the spray treatment reduced the quantity of pods and yield per plant. The effect, however, might not last until M2 generation. Aldrin's potential genetic risks have been discussed.
