Abstract

Influence of preparation VESB, containing 20OH-ecdysterone, on the level of polyteny of giant chromosomes was investigated in Drosophila melanogaster Meig. It was shown that the effects of the preparation depend on its concentration and genotype. It was found the stimulative effect of the preparation under its addition in medium within 0.01 mkg/ml concentration, whereas 1 mkg/ml concentration has depressive action. Close positive correlation between chromosomes polyteny level and heat shock resistance, body mass, fertility and negative correlation between level of polyteny and development speed were shown as well.
