- How do the authors of the study interpret the information shown in Figure 3? (Choose one.) Group of answer choices The speed (number of days) at which fig saplings die from wilting disease is much faster when the saplings are inoculated with two species of fungi at the same time, compared to only one of the species. The number of days which saplings survive is significantly longer when fig saplings are inoculated with C. ficicola and F. kuroshium at the same time, compared to just inoculated with C. ficicola. There were significantly higher densities of C. ficicola than of F. kuroshium found in plants suffering from fig wilt disease. The number of saplings dying from fig wilt disease was significantly higher in plants inoculated with C. ficicola than in plants inoculated with F. kuroshium plus C. ficicola.Discuss how P. fluorescens can be modified to make it a more effective biocontrol agentagainst the fungal pathogen P. ultimum.Why do yeasts generally have to be cultured for longer periods than most bacteria?
