Fig. 6From: Metabolomic analyses reveal substances that contribute to the increased freezing tolerance of alfalfa (Medicago sativa L.) after continuous water deficitScatter plots of scores of the orthogonal partial least squares discriminant analysis for identified differential metabolites in the seven comparisons. WW and WD: substrate moisture at 80 and 25% of water-holding capacity, respectively. WD_1, 2, 3 and WW_1, 2, 3 represent samples collected at the ends of phases 2, 3, and 4, respectivelyBack to article page
