Botrytis cinerea infection-PDA plug on the 4th poplar leaf. From a seven-day-old B. cinerea culture on a Potato-Dextrose-Agar (PDA) plate, a B. cinerea-inoculated PDA plug was punched out with a 6 mm cork borer. a The B. cinerea-inoculated PDA plug was transferred to the 4th fully expanded Populus x canescens leaf and placed in between major veins with a needle. b Thereafter, the leaf was sealed with a plastic bag
