Figure 1.
Icacina tricantha fractions and icacinol (1) effects on seed germination. Extractions were conducted as described in Experimental Section. S2 (EtOAc-soluble fraction) and 1 were mixed in top agarose with seeds at concentrations indicated in the figure; 100 seeds per replicate were sown. Seed germination was scored 72 h postplating at 20°C for Arabidopsis and at 28°C for rice.
