Abstract
Light plays an essential role in the outcome of plant-pathogen interactions. In this study, the effect of pre- and post-inoculation light quality on Botrytis cinerea disease development in strawberry leaves was investigated. Circadian variations in leaf susceptibility to Botrytis cinerea were tested by inoculating at 5 h, 12 h, or 16 h after the start of photoperiod. The effects of 4 h and/or 12 h of red or blue light combined with white light in a 16 h photoperiod on leaf susceptibility and metabolites were studied. Light presence significantly decreased leaf susceptibility to Botrytis irrespective of light quality. Leaf susceptibility to B. cinerea showed significant circadian variations. Susceptibility was highest in leaves inoculated 12 h after the start of photoperiod followed by incubation in the dark. When disease development took place under the light regime, the shorter the light period after inoculation the stronger the disease symptoms. Twelve hours of red light radiation in a 16 h photoperiod increased, while 12 h blue light radiation decreased leaf resistance, resulting in alterations in the circadian variation of leaf susceptibility. These alterations correlated with changes in leaf metabolites, such as hydrogen peroxide, total phenolics and hexoses. Overall, we conclude that twelve hours of red light followed by white light in a 16 h photoperiod efficiently increased leaf resistance to B. cinerea.
