| Abstract: | The study shows that La2O3 at a concentration of 30-450 mg.L-1 could inhibit the growth of S. sclerotiorum in both solid and liquid media and the inhibition effect was increased with its increasing concentration. The activity of pectinase produced by S. sclerotiorum in liquid medium was also increased with increasing La2O3 concentration. |
