AN APPARATUS FOR DETERMINING THE EFFECTS OF TEMPERATURE AND HUMIDITY ON GERMINATION OF FUNGOUS SPORES

摘要

An apparatus is described by which fungous spores can be uniformly distributed on microscope slides. A procedure is outlined whereby Petri dishes can be converted into airtight humidity chambers, the humidity of which can be readily checked. It was found that above 94 relative humidity maximum germination amongBeauveria bassianaspores occurs at 28 deg;C.
