Abstract: Meadowfoam ( Limnanthes alba Hartweg ex. Benth.) seedmeal, a coproduct of oil extraction from meadowfoam seeds, has been found to increase the growth of greenhouse plants when added to the growing medium. (3-Methoxyphenyl)acetonitrile (3-MPAN) is a biologically active glucosinolate degradation compound previously identified at high levels in meadowfoam seedmeal. 3-MPAN was tested as a foliar spray at several concentrations (0 μ m , 0.18 m m , 0.37 m m , 0.73 m m , 2.2 m m , and 7.3 m m ) on lime basil ( Ocimum basilicum L.), spearmint ( Mentha spicata L.), cuphea ( Cuphea lanceolata L.), and French marigold ( Tagetes patula L.) seedlings grown in the greenhouse. 3-MPAN increased the fresh and dry weights of all four species tested. However, this effect was dose-dependent among species with spearmint growth higher at all 3-MPAN application rates, whereas basil growth was promoted at only the 2.2-m m rate. 3-MPAN increased the tissue concentrations of the secondary compound (−)-carvone at the 7.3-m m application rate. In addition, 3-MPAN added to sterile nutrient media stimulated the growth of spearmint plants in vitro. These results indicate that 3-MPAN may have applicability as a postemergent growth stimulant for a wide variety of plants.
