highly significantP < 0.001
A comparative analysis of the four clusters indicated a highly significant difference (df = 3, P < 0.001) among them for five of the six variables (soluble sugars: df = 3, Kruskal-Wallis chi-squared = 13.1, P = 0.004, Fig 4A ; insoluble sugars: df = 3, F = 13.1, P = 0.01, Fig 4B ; pH: df = 3, F = 17.7, P < 0.00001, Fig 4C ; Flavonoids: df = 3, F = 20.95, P < 0.00001, Fig 4D and Phenols: df = 3, F = 9.11, P < 0.001, Fig 4E ) that significantly described the clusters obtained.
