摘要：

Extracted alfalfa saponins and leaf meal extracts from alfalfa influenced the growth rate of some fungi more than others. Of seven fungi whose growth rate was studied on media to which different concentrations of extracted alfalfa saponins or Leeben, a commercial saponin, were added, only Trichoderma viride was found highly sensitive at concentrations below 1 mg of saponin per milliliter of medium. A correlation coefficient of[long dash]0. 952 was found between the growth of T. viride on 2% potato-dextrose-agar containing leaf meal extracts from 36 F1 and S1 plant families and saponin percentage. This, together with a correlation coefficient of[long dash]0. 922 between the growth of T. viride on media containing leaf meal extracts from individual alfalfa plants and saponin percentage, suggests the use of T. viride for bioassays for saponins.
