Samenvatting Teleutosporen vanPuccinia horiana P. Henn. kiemen spoedig na hun vorming. Promycelia gekiemd op objectglaasjes zijn langer en smaller dan promycelia gekiemd in situ. Het promycelium is meestal driecellig, soms ook een- of tweecellig. Een promycelium produceert één tot drie, meestal twee basidiosporen. Deze zijn aanvankelijk een- of tweekernig, later meerkernig. Basidiosporen kiemen snel op natte objectglaasjes en bladeren. De basidiosporenkieming kan op drie onderling iets verschillende wijzen verlopen.
Notes:
Abstract Teleutospores ofPuccinia horiana P. Henn. germinate soon after their formation. Promycelia germinating on microscope slides have a tendency to grow in length and become narrow in outline; when germinating in situ, developing promycelia are short and stout, and show a lobed apical cell. The promycelium is usually three-celled, but at times it is one- or two-celled. Two basidiospores are usually produced by each promycelium (observed range one to three). Basidiospores are uni- or binucleate at first, but later become multinucleate. They germinate rapidly on microscope slides and on host leaves, when sufficiently wet. Three different patterns of basidiospore germination were observed.
