Gibberella intermedia the pathogen of St. John's Wort, coneflower and marshmallow in Serbia

Abstract

Gibberella intermedia (Kuhlmann) Samuels et al. (anamorf: Fusarium proliferatum /Matsushima/ Nirenberg) was isolated from seeds of St. John's wort, marshmallow, and coneflower, as well as from roots and stalks of marshmallow and roots of coneflower. These plants had symptoms of leaf chlorosis, malformation, withering and plant dwarfing and were collected from several localities in Serbia during five-year investigations of mycopopulations of the mentioned plants. The morphological characteristics of the pathogen were described.

Gibberella intermedia (Kuhlmann) Samuels et al. (anamorf: Fusarium proliferatum /Matsushima/ Nirenberg) je konstatovana na belom slezu, ehinacei i kantarionu i to na semenu, korenu i stablu, kao i na rasadu ehinacea. Osnovni simptom zaraženih biljaka G. intermedia su bili: propadanje klijanaca, trulež korena i korenovog vrata, patuljavost, asimetričan porast, uvelost, hloroza i smežuranost listova. Uzorci zaraženog biljnog materijala bili su poreklom iz okoline Pančeva, Zrenjanina, Banatskog Novog Sela, Inðije, Rume i Stare Pazove. U radu su date morfološke, fiziološke i patogene karakteristike izolata G. intermedia.
