A Preliminary Investigation of Water‐Soluble Inhibitors in Atriplex Polycarpa Using the Fungus Trichoderma Viride 1

The leafy material from Atriplex polycarpa contains 1.15% saponin. Comparative inhibition of Trichoderma viride mycelium indicated that saponin from A. polycarpa was either much more potent than commercially available saponin from the bark of Quillaja, or that other water-soluble inhibitors were also present. Distilled water, dripping through A. polycarpa plants to simulate rain, also removed inhibitory substances from A. polycarpa.
