Abstract

Glavni predstavnici porodice tikvenjača (Cucurbitaceae L.) se kultiviraju ponajviše radi ishrane čovjeka. Ovisno o vrsti, koriste se u sirovom ili prerađenom obliku. Smanjeni prinos i/ili štete u skladištima uzrokovane fitopatogenima znatno utječu na uspješnost proizvodnje. Bakterije, kao predstavnici fitopatogenih prokariota, mogu uzrokovati značajno smanjenje prinosa i kvalitete proizvoda. Najvažnije bakterije koje se javljaju na tikvenačama su: Pseudomonas syringae pv. lachrymans, Erwinia tracheiphila, Xanthomonas cucurbitae, Acidovorax citrulli, Serratia marcescens, Pseudomonas syringae pv. syringae i Pectobacterium carotovorum subsp. carotovorum. Analiza bakterija prisutnih u i na biljnim organizmima, kao i laboratorijska identifikacija uzročnika bakterioza tikvenjača, korisna je za proizvodnu praksu jedino ako se obavi pravovremeno. Uzorkovanje za potrebe laboratorijskih analiza uvjetovano je prepoznavanjem simptoma bolesti u polju. Rad donosi pregled suvremenih znanstvenih i stručnih znanja o bakteriozama tikvenjača, njihovoj raznolikosti, prisutnosti i pojavnosti uzročnika i epidemiologiji, te o specifičnostima njihove simptomatologije. Predstavljene su osnove temeljnih dijagnostičkih laboratorijskih protokola namijenjenih identifikaciji bakterijskih patogena tikvenjača, kao i strategije njihovog suzbijanja, s naglaskom na ekonomski i ekološki prihvatljive tehnike zaštite bilja koje je neophodno primjenijivati u cilju smanjenja ili sprječavanja šteta od bakterioza.

Abstract (english)

The main representatives of the plant family of cucurbits (Cucurbitaceae L.) are cultivated mainly for human consumption. Depending on the species, they are used raw or processed. Reduced yields and/or storage losses caused by phytopathogens significantly affect production. Bacteria, as one of the representatives of plant pathogenic prokaryotes, can cause significant reduction of yield and quality. The most important bacterial species that occur on cucurbits are: Pseudomonas syringae pv. lachrymans, Erwinia tracheiphila, Xanthomonas cucurbitae, Acidovorax citrulli, Serratia marcescens, Pseudomonas syringae pv. syringae and Pectobacterium carotovorum subsp. carotovorum. Analysis of bacteria present in and on plant organisms, as well as laboratory identification of species causing bacterioses on cucurbits, is useful for production praxis only in case when it is performed on time. Sampling for laboratory analysis is conditioned by the recognition of disease symptoms in the field. The paper provides an overview of modern scientific and professional knowledge about bacterioses of cucurbits, their diversity, presence and occurrence of pathogens and epidemiology, and the specifics of their symptomatology. The basics of general diagnostic laboratory protocols intended for the identification of bacterial pathogens of cucurbits, as well as strategies for their control, are presented. Economically and environmentally friendly plant protection techniques that need to be applied, in order to reduce or prevent damage caused by bacterial diseases, were emphasized.
