ЭФФЕКТЫ ФИЗИКО-ХИМИЧЕСКИХ ВОЗДЕЙСТВИЙ НА ЛЕКАРСТВЕННЫХ РАСТЕНИЯХ

Abstract

This research is devoted to investigation effects of presowing treatment by electromagnetic radiation of the millimeter-wave range (EMR) and exogenous aminolevulinic acid (ALA) in ultra-low concentrations in medicinal plants Calendula officinalis L. and Nigella sativa L.. Microwave EMR in two frequency bands, 53.57-78.33 GHz (wide range mode) and 64.00-66.00 GHz (narrow range mode), has been selected to study the physical effects on seeds, with a treatment exposure time of 20, 12, or 8 min and ALA in micro- and nanoconcentrations have been used: 1) 10-6; 2) 10-7; 3) 10-9; 4) 10-11. The experiments were conducted under laboratory and field conditions. Morphometric and biochemical parameters of plants at different stages of ontogenesis were studied. Original data about EMR and ALA influence on the content of phytohormones in seedlings and the qualitative composition and quantitative content of saturated and unsaturated fatty acids, as well as individual biologically active compounds in the seeds of the plants C. officinalis and N. sativa under study were obtained.
