Sažetak
Cilj istraživanja je bio upoznavanje raznih tipova simptoma nedovoljno proučavanih oboljenja na gajenom belom slezu, ehinacei, kantarionu i žalfiji, ispitivanje etiologije, kao i identifikacija prouzrokovača bolesti lekovitog bilja u našoj zemlji. Uzrok bolesti kod ovih biljaka mogu biti gljive iz različitih rodova, među kojima su najčešće one iz roda Fusarium. Iz semena tih biljaka, kao i sa korena i stabla belog sleza i korena ehinacee, izolovana je Gibberella moniliformis Win. anamorf: Fusarium verticillioides /Sacc./ Nirenberg. Rađeno je sa ukupno 37 izolata Gibberella moniliformis, izolovanih u periodu od 2002. do 2006. godine. Iz uzoraka sakupljenih na više lokaliteta, izolacija iz nadzemnih i podzemnih delova obavljena je po standardnom postupku, uz korišćenje sledećih podloga: PDA, SNA, CA i CLA. Za proučavanje teleomorfnog stadijuma korišćena je modifikovana metoda. Uz identifikaciju patogena, opisani su simptomi i ispitana patogenost. Trulež korena i korenovog vrata belog sleza, ehinacee, kantariona i žalfije, koju prate simptomi patuljastog, asimetričnog porasta, uvelosti, hloroze i smežuranosti listova, je oboljenje prisutno u svim ispitivanim područjima. Bolest značajno umanjuje prinose ovih komercijalno važnih biljnih vrsta.
Abstract
Plant diseases on mallow, coneflower, St. John's wort and sage in Serbia were studied only in small extent. Causal agents in these plants can be fungi belonging to different taxa, among them the most often species from the genus Fusarium. Gibberella moniliformis Win. anamorf: Fusarium verticillioides /Sacc./ Nirenberg was isolated from the seeds of marshmallow, St. John’s wort, coneflower, and sage, as well as from the stem and root of coneflower. The aim of investigation was to recognise symptoms of certain diseases in cultivated medicinal plants and identification of causal agents. In 37 isolates of Gibberella moniliformis, isolated during the period 2002-2006, using selected nutritive media (PDA, SNA, CA and CLA), standard and modified methods (Leslie 1991), Fusarium verticillioides was recorded, it's symptoms were described, as well as it's pathogenicity. Root rot in marshmallow, St. John’s wort, coneflower, and sage, followed by symptoms of asymmetric growth, chlorosis and wilt is often present in cultivated plants in areas examined. Disease significantly decreases yields of these commercially important plant species.
