Only a few of his original findings will be mentioned here. He found that bulb juice of Allium cepa and A. sativum contained inhibitors as does root sap of Armoracia lapathifolia, tuber sap of Brassica caulocarpa, and fruit juice of Citrus aurantium, C. limonia, and C. maxima. He stressed the widespread occurrence of potent seed germination inhibitors in various species of the Cruciferae and empahsized that the evidence indicates that mustard oils are the chief inhibiting substances in such cases.

Lettuce was not used in growth tests, but growth of all other species was inhibited by certain concentrations of some extracts. Growth was decreased most by leaf extracts, and mature leaves produced more inhibitory material than young leaves or leaves of an intermediate age. Treatment of the aqueous solutions with Norit eliminated much of the inhibitory activity, but autoclaving or inoculation 40 2 .

Kali reduced germination and radicle growth of radish. However, only one identified phy­ totoxin (ferulic acid) inhibited germination and seedling growth of Russian thistle. Mohnot and Soni (1976) demonstrated that water extracts of air-dried leaves of Salvadora oleoides inhibited seed germination and root and shoot growth of seedlings of sorghum. Anaya and Gomez-Pompa (1971) demonstrated that extracts of leaves and fruits of piru (Schinus molle) were strongly inhibitory to seed germination and seedling growth of cucumber {Cucumis sativus) and wheat.
