Figure 5 in Anatomical characteristics and resprouting capacity of the underground organs of Bohemian knotweed (Polygonum ×bohemicum)

Figure 5. Resprouting rate for each pith color class (time days = 70; ntot = 201) in Polygonum ×bohemicum. (A) using the six pith brightness classes according to grayscale [0–1] intervals and (B) using the six color classes for which the reference RGB color is indicated in Hex Code. Differences in resprouting capacities (resprouting rates) were significant among pith brightness classes (Χ2 = 29.4, df = 5, P-value <0.01), as well as among pith color classes (Χ2 = 31.1, df = 5, P-value <0.01).
