摘要：

The epicuticular lipids of alfalfa (Medicago sativa L.) were analysed by gas chromatography to determine if differences exist between plants with varying degrees of resistance to spotted alfalfa aphids, Therioaphis maculata (Buckton). Leaf surfaces of some resistant plants were found to have as much as 50% more wax esters than did those from plants that were susceptible to spotted alfalfa aphids. This difference was found in one set of sibling plants, which had been selected for spotted alfalfa aphid resistance, but not in a resistant plant population with a wider genetic base. Amounts of epicuticular lipids were found to be similar for leaves of the same age from stems of the same plant and from plants with similar genetic backgrounds which were grown under the same conditions.
