This data is collected from two experiments, one in 2018 and one in 2019, that left untreated or inoculated grapevines with Diplodia seriata, Neofusicoccum parvum, Phaeomoniella chlamydospora, or mock-inoculated, and then two months later inoculated with one of the three pathogens. Grapevine stem phenolic levels were measured at the time of the second inoculation on a different branch, and comparisons were made between pathogen infected plants or those left non-inoculated. Lesion sizes of the second inoculations also were compared to examine the effects on the first inoculation on these. Lesion lengths were measured in mm, and all phenolic compound levels were measured in mg/g FW amounts. Resources in this dataset:Resource Title: Fungal Pathogen Induction of Grapevine Stem Phenolics. File Name: Fungal Pathogen Induction of Stem Phenolics.xlsxResource Description: Data from experiments conducted in 2018 and 2019, available on different tabs. Data from 2018 was from an experiment that had potentially compromised effects due to loss of greenhouse environmental controls and issues establishing fungal canker pathogen infections. Lesion lengths are provided in mm, and all phenolic levels are provided in mg/g FW stem tissues.
