Alenina S. Effects of He-Ne laser irradiation on adaptive quantitative features expression and bioelectrical properties of cell nuclei in inbred lines and hybrids of Drosophila melanogaster

Dissertation is devoted to the problems of heterosis and variability of adaptive traits in Drosophila melanogaster under conditions of low energy laser irradiation influence. Effects of He-Ne laser radiation treatment were investigated on the organism and subcellular levels. Role of genotype and exposition components in determination of quantitative traits connected to adaptation and reproduction was studied. It was found that He-Ne laser radiation treatment on the early stages of ontogenesis results in changes of mentioned traits. Manifestation degree of heterosis effect de-pended also on treatment procedure. Correlation between adaptive traits and bioelectrical properties of cell nuclei was confirmed. The results of work are of theoretical value and should be taken into consideration for investigations to find out low energy laser irradiationapplications for selection practice and medicine.
