From: A glass bead semi-hydroponic system for intact maize root exudate analysis and phenotyping
Root exudates collected with 1 mM CaCl2 or MQ in the genotype Ames 20140. Blue bars: analysis of exudates collected with MQ or CaCl2. Green bars: analysis of the effect on the recovery of exudates after a clean-up step using MCX-SPE cartridges to remove salts from the samples collected with  MQ and added CaCl2. a Phytohormones detected (ABA, cZ, JA, JA-Ile, Me-IAA, tZR, SA, IAA). b Amino acids, group 1, detected in MQ and CaCl2 with no differences (GABA, His, Ile, Leu, Lys, Phe, Pro, Trp, Tyr, Val). c Amino acids, group 2, detected in low concentration in CaCl2 (Ala, Arg, Asn, Asp, Gln, Glu, Met, Ser, Thr). d Sugars (Ara, Fru, Gal, Glc, Man, Suc, Tre, Xyl). Statistical differences detected with a T-test, each pair, only significant differences shown *p ≤ 0.05, **p ≤ 0.01. Ames 20140, n = 3. Boxplot: Box, interquartile range (IQR); line inside the box, median; end of the box, upper (Q3) and lower (Q1) quartiles; dots beyond the extreme lines show potential outliers
