Fig. 2From: Metabolomic analyses reveal substances that contribute to the increased freezing tolerance of alfalfa (Medicago sativa L.) after continuous water deficitDry weights of aboveground and belowground alfalfa parts in the four experimental phases. WW and WD: substrate moisture at 80 and 25% of water-holding capacity, respectively. The significances of differences between and within phases were evaluated using a multiple-range test. Different letters indicate significant differences (P < 0.05)Back to article page
