Extracts were prepared from 40 g (fresh weight) of foliar material. HPLC runs were repeated twice (SD ≤ 1%). Peaks below detection level were specified as nondetectable (ND). Two independent experiments were performed and showed similar results. Presented data are from one representative experiment.
