  1. Identification methods: MS, comparison of the mass spectrum with those of computer mass libraries Wiley, Adams, and NIST 08; RI, comparison of retention index with those reported in Adams and NIST 08; RI, linear retention indices on DB-5 MS column, experimentally determined using homolog series of n-alkanes Irrigation at 100% FC, 75% FC, and 50% FC, corresponding to full-irrigation, moderate water stress, and severe water stress, respectively, C control, HA humic acid, B bacterial, AA amino acid.
