Chronic low-dose γ-irradiation of Digitalis purpurea and Aerva lanata plants in vitro have led to an increase in the content of carotenoids and flavonoids in the leaves at the beginning of the post-radiation period. In the following, the content of pigments and flavonoids decreased in comparison to the control samples. For Polemonium caeruleum such...

Aim. Long-term studies of the effect of sublethal doses of pre-sowing low-LET ionizing radiation on seeds have demonstrated the effectiveness of radiation biotechnology to stimulate the accumulation of pharmaceutically valuable secondary metabolites in medicinal raw materials of a number of common medicinal plants in Ukraine. The aim of this resear...

The method of increasing the content of the amount of phenols and flavonoids in the raw materials of medicinal plants by pre-sowing radiation treatment of seeds. The utility model belongs to agriculture, directly to the technology of cultivation of medicinal plants and can be used for pre-sowing treatment of chamomile seeds and St. John's wort. To...

The monography presents the authors' experience and a brief overview of the research of scientists from other countries in the study of the effect of ionizing radiation on the processes of secondary metabolism in medicinal plants. The main idea of the study was to develop biotechnology, which consists in the selection of radiation doses of gamma or...

Aim. The purpose of this work was to determine the dose of g- and X-ray pre-sowing irradiation of seeds of Hypericum perforatum L., causing an increase in biomass and the accumulation of flavonoids in medicinal raw materials. Methods. X-ray and g-irradiation of seeds, biometric methods, flavonoids extraction, quantification of flavonoid content in...

Method of increasing flavonoid content in raw materials of medicinal plants by pre-sowing radiation treatment of seeds. The utility model belongs to agriculture, directly to the technology of cultivation of medicinal plants and can be used for pre-sowing treatment of chamomile seeds and St. John's wort. To implement the utility model, dry seeds are...

Aim. Presowing radiation exposure of seeds is offered to apply as modification factor of secondary metabolites accumulation in medicinal plants. Aim of studying was to choose doses of both gamma- and X-ray exposure of Chamomilla recutita L. seeds that would lead to increasing synthesis of secondary metabolites and biomass. Methods. Both X- and gamm...

Digitalis purpurea L. is the source of a number of biologically active substances used for medical purposes. Agrobacterium rhizogenes-transformed plants show changes in the secondary metabolism. The influence of acute exposure to ionizing radiation on the modification of the pigment system and accumulation of flavonoids in Ri-transformed regenerate...

Results of the study of effect of preliminary γ-irradiation of maize seeds and cadmium chloride entering into the nu-trient medium of sprouts on their absorption and growth characteristics in the water culture conditions have been pre-sented. The radiocapacity factor by the tracer¹³⁷Cs was used as the absorption characteristic. Seeds were irradiate...

Objective: To study the influence of long-term gamma-irradiation with low dose rate (13×10-6 cGy/s) on the body, testes and ventral prostate, development of laboratory rats, as well as quantitative parameters of sperm production along with kinetic characteristics of spermatozoa. Materials and methods: The experiments were performed on laboratory...

Objective. Show the possibility of method of the radiocapacity factor using for the study the phenomenon of adaptation of maize plants to the action of toxic factor - namely , introducing into the habitat of cadmium chloride solution. This method is proposed as convenient and adequate indicator of change of state of the objects under chemical stres...

Objective: To show the possibility of a new approach using for the evaluation of biota's state in the ecosystem under the independent and combined effect of radiation and chemical factors. It is based on a radiocapacity factor analysis, defined as the maximum radionuclide quantity accumulated in biotic components of ecosystem that does not disturb...
