                         tolerance of the insect-pathogenic fungus Metarhizium robertsii, 
                         but little is known if low- or high-white light irradiances induce 
                         different stress tolerances. The fungus was grown either in the 
                         dark using two culture media: on minimal medium (Czapek medium 
                         without sucrose = MM) or on potato dextrose agar (PDA) or PDA 
                         medium under five different continuous white light irradiances. 
                         The stress tolerances of conidia produced on all treatments were 
                         evaluated by conidial germination on PDA supplemented with KCl for 
                         osmotic stress or on PDA supplemented with menadione for oxidative 
                         stress. Conidia produced on MM in the dark were more tolerant to 
                         osmotic and oxidative stress than conidia produced on PDA in the 
                         dark or under the light. For osmotic stress, growth under the 
                         lower to higher irradiances produced conidia with similar 
                         tolerances but more tolerant than conidia produced in the dark. 
                         For oxidative stress, conidia produced under the white light 
                         irradiances were generally more tolerant to menadione than conidia 
                         produced in the dark. Moreover, conidia produced in the dark 
                         germinated at the same speed when incubated in the dark or under 
                         lower irradiance treatment. However, at higher irradiance, 
                         conidial germination was delayed compared to germination in the 
                         dark, which germinated faster. Therefore, growth under light from 
                         low to high irradiances induces similar conidial higher stress 
                         tolerances; however, higher white light irradiances cause a delay 
                         in germination speed.",
