FIGURE 3 in An emended description of Neofusicoccum brasiliense and characterization of Neoscytalidium and Pseudofusicoccum species associated with tropical fruit plants in northeastern Brazil
FIGURE 3. Mean lesion length (mm) caused by Botryosphaeriaceae species associated with dieback and stem-end rot in several tropical fruit trees from Northeast Brazil: 45 days after inoculation in stems of young plants of caja-umbu, 15 days after inoculation in stems of young cashew plants and four days after inoculation in injured mango fruits. Bars above columns represent the standard error of the mean. For each host, columns with the same letter do not differ significantly according to Scott–Knott's test at a = 0.05.
FIGURE 2 in An emended description of Neofusicoccum brasiliense and characterization of Neoscytalidium and Pseudofusicoccum species associated with tropical fruit plants in northeastern Brazil
FIGURE 2. Mycelial growth (A) and in vitro growth rate (B) of Botryosphaeriaceae species on the third day of incubation in different culture media. Fig, 2A: There was a positive interaction between the factors of culture media and species. Thus, the same uppercase letters for each culture medium within the species factor indicate no difference among media, and the same lowercase letters within the species factor for each culture medium indicate no difference among species. The means were compared by the Scott-Knott test at P = 0.05. Fig. 2B: There was no positive interaction between the factors of culture media and species. Thus, averages followed by the same lowercase letters within each species do not differ by Scott-Knott's test at P = 0.05.
