Stability and destructive activity of orchard microbiota to modern pesticides

Abstract

In the current work we modelled the impact of CO2 and temperature on the growth and development of the invasive species Ambrosia artemisifolia L. We used the physical-chemical methods, laboratory methods, modelling methods and statistical analysis. Our results indicate that the some of the factors of global warming (CO2 and temperature) stimulate the growth and development of ragweed plants. Taking in account the prediction of global climate changes and increasing the concentration of CO2 in the atmosphere twice between the 2050 and 2100 it can be expected to gain the invasions of Ambrosia artemisifolia L. Increasing CO2 stimulates growth of ragweed stems, while the combined effect of increasing CO2 and temperature stimulates growth of shoots in Ambrosia artemisifolia L. In general our study shows that increasing concentration of carbon dioxide in air and high air temperature have positive effects on the development and growth of Ambrosia artemisifolia L. and thus on the invasive expansion processes of the current species in terms of increasing ongoing global warming of Earth’s atmosphere
