Figure 4 in Clonal mechanisms that matter in Agave fourcroydes and A. sisalana invasions in drylands: implications for their management

Figure 4. Mean and standard deviation of rooting rates of Agave fourcroydes and A. sisalana bulbils under experimental plots (greenhouse and natural conditions). Different letters indicate statistical differences (p-values <0.001) between planting conditions for Fisher's exact tests. The lower case letters correspond to the comparisons in the experiment under natural conditions, and the upper case letters refer to those in the greenhouse experiment.
