Western soapberry (Sapindus drummondii Hook & Arn.) seeds were collected in Sept. 1982 and scarified with acid or hot water, or treated by freezing. The seeds were sown immediately or after cold-moist stratification for 90 days. Best germination was achieved with acid scarified and stratified seeds followed by hot water treatment plus stratification and freezing plus stratification. Stratification significantly increased the germination of all treatments by a combined average of 25%. Acid scarification for 60 or 90 min provided better germination than scarification periods of 30 or 120 min. Seeds collected in Nov. 1982 and Mar. 1983 germinated as well as seeds collected in Sept. 1982. For maximum germination, fall or winter collection of seeds followed by 60 min acid scarification and 90 days cold moist stratification is recommended.
