Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA) Model during germination of Davida involucrata at positive ion node.

Pairwise group	R2X	R2Y	Q2
6M-CK	0.44	1.00	0.90
12M–6M	0.47	1.00	0.93
18M–12M	0.48	1.00	0.94
24M–18M	0.34	1.00	0.91
30M–24M	0.42	0.99	0.81

R²X and R²Y represent the cumulative degree of interpretation of the model to the X and Y variables, respectively. Q² denotes goodness of prediction.
