Effect of t>pe of wounding. Means of three experiments. Treatments were NW = Nonwounded with a 10 jjl droplet of sterile distilled water, NI = Nonwounded, inoculated with , CH = Cut-wounded and a 10 jji droplet of sterile distilled water applied, CI = Cut-wounded and inoculated with , B = B urn-wounded, not inoculated, B \V = Burn-wounded and a 10 pi droplet of sterile distilled water applied. BI = Bum-wounded and inoculated with G. fraxini. In fig. 3B-F, the treatment labelled NI corresponds to treatment here called BW. B. Effect of inoculum concentration (conidia per leaf disc) on size of lesions on green ash leaf discs inoculated with Means of three experiments. C. Effect of leaf age on size of lesions on green ash leaf discs noculated with Means of two experiments using leaves aged 10,20 and 30 days after emergence. Leaves at all stages collected at one time. D. Effect of leaf age on size of lesions on green ash leaf discs inoculated with Means of two experiments using leaves aged 15, 20 and 25 days after emergence. All leaves removed at one time. E. Effect of temperature on size of lesion on green ash leaf discs inoculated with This figure shows the results of two experiments plotted together. Each experiment consists of an inoculated treatment and a noninoculated control, both bum-wounded. F. Effect of temperature on lesion size on green ash leaf discs inoculated with from four sources. Means of two experiments. Legend indicates source of cultures: LS = Leaf spots, AS = Ascospores,
