Continuous illumina- tion of these plasmodia resulted in sclerotium formation in … To maintain viability, plasmodial Physarum should be subcultured weekly. Available in both plasmodial and sclerotial stages. To determine whether P. polycephalum releases volatile terpenoids like dictyostelid social amoebae, plasmodia of P. polycephalum were cultured on agar plates with oak flakes as nutrient source and subjected to volatile profiling at two time points: 8 days and 18 days after the transfer of plasmodia to a fresh agar plate.
