Abstract:
Only induction by sun or ultraviolet light induced sporulation of Alternaria porri f. sp. solani in cultures. On potato leaves few spores were produced without induction, some by drying the conidiophore-bearing leaves in darkness, more by exposing wet leaves to fluorescent light and most by illuminating and drying the leaves. Increases in light intensity from 9·5 to 195 microeinsteins (μE) and of exposure up to 8 and 12 h resulted in increased sporulation. However, the relative efficiency of every light unit (μE) and every exposure unit (min) of induction decreased with increase of these units. The response of conidiophores on completely dried leaves to the inductory effect of light suggested a photochemical reaction. After the pathogen was induced for sporulation on leaves, then stored dry at 20 °C in the dark, the "memory" of induction lasted for about 16 to 21 days. © 1976.
