Abstract

Klimatske promjene imaju značajan utjecaj na korisne asocijacije između biljaka i mikroorganizama poput bakterija i gljiva koje potiču rast biljaka (PGPB i PGPF), mikoriza i rizobija. Promjene u temperaturi, razini ugljičnog dioksida, količini padalina te učestalosti ekstremnih vremenskih događaja mogu nepovoljno utjecati na ove odnose. Primjerice, povišene temperature i suša mogu smanjiti efikasnost rizobija u fiksaciji dušika, dok kod mikoriza mogu dovesti do poremećaja unosa vode i hranjivih tvari za biljku. Promjene u reakciji i sastavu tla te dostupnosti hranjivih tvari uvjetovane klimatskim promjenama mogu smanjiti broj korisnih mikroorganizama ili promijeniti njihove funkcije. U ovo radu sabrana su dosadašnja istraživanja o utjecaju pojedinih klimatskih čimbenika na biljke i njihove mikrobne partnere što je važno za održavanje stabilnosti ekosustava, produktivnosti usjeva te za razvoj održive poljoprivredne prakse.

Abstract (english)

Climate change has a significant impact on beneficial associations between plants and microorganisms such as plant growth-promoting bacteria and fungi (PGPB and PGPF), mycorrhizae and rhizobia. Changes in temperature, carbon dioxide levels, rainfall and the frequency of extreme weather events can adversely affect these relationships. For example, elevated temperatures and drought can reduce the efficiency of rhizobia in nitrogen fixation, while in the case of mycorrhizae they can lead to disturbances in the intake of water and nutrients for the plant. Changes in the reaction and composition of the soil and the availability of nutrients caused by climate change can reduce the number of beneficial microorganisms or change their functions. This paper summarizes previous research on the influence of certain climatic factors on plants and their microbial partners, which is important for maintaining ecosystem stability, crop productivity and for the development of sustainable agricultural practices.
