    摘要： The present invention provides a formulation for increasing the synthesis and accumulation of essential oil in aromatic plants and other plants. The formulation disclosed herein comprises a resistance inducer, such as an isomer of amino butyric acid or another amino acid, which is capable of increasing the synthesis of essential oil in an aromatic plant. The formulation may further comprise secondary metabolites as well as a carrier. Aromatic plants that may be used in the present invention include, but are not limited to, rose-scented geranium (Pelargonium graveolens) and menthol mint (Mentha arvensis). The present invention also provides a method of increasing the essential oil content in aromatic crops and other plants.
