Abstract
A serious blight caused by Alternaria alternata was found to affect the leaves, flowers and propagules of the grey mangrove, Avicennia marina var. australasica, along the southeastern coast of Australia. The isolate exhibited a broad temperature response (15–30 °C) with an optimum of 30° for both conidial germination and growth in vitro. Germination of conidia occurred after 3.5 h and branching of germ-tubes began after 14 h of incubation at 30°. Conidia germinated at salinities as high as 6% NaCl. Maximum germination occurred at humidities of 90% or greater. The isolate grew satisfactorily on most media with maximum growth on 2% malt extract agar. Light dependent sporulation in vitro was observed within 4 days of mycelial inoculation.
