| Abstract: | HgCl2 was used at up to 10 mg l–1 as an elicitor of phytoalexins in sweet potato (Ipomoea batatas (L.) Lam. cv Centennial) cell suspension cultures. Maximum stimulation of a coumarin compound was after one day of exposure using 1 mg HgCl2 l–1. The compound was identified by HPLC and GC-MS analyses as 7-hydroxycoumarin (umbelliferone). |
