Abstract
Spore germination and the viability of the mycelial fragments of the microscopic fungi Alternaria alternata, Penicillium spinulosum, and Mucor hiemaliswere studied with respect to the action of certain ecological factors: sucrose concentration (0, 0.2, 2, 10, and 100 g/l), temperature (4, 20, 25, and 30°C), pH (3.5, 4.0, 5.0, 6.2, and 7.0), and cadmium concentration (0, 2, 10, and 100 mg/l). The spore germination and the viabilities of different mycelial fragments were found to reach their maxima at different values of the ecological factors studied. This finding suggests that the vegetative and asexual types of reproduction of microscopic fungi may have different ecological optima.
