Effects of Plant Growth-Promoting Microorganisms (PGPMs) on Plant Induction Responses and Subsequent ＂Spodoptera Litura＂ Performance
並列摘要
Plant-growth promoting microorganisms (PGPMs) have become important microbial fertilizers lately. This soilborne microbe-plant interaction may also affect plant defense responses. However, little is known about the effect of PGPMs on induced defensive responses of various plant species. In this study, we assessed the effects of PGPMs and plant species on plant's chemistry and performance of the subsequent insect herbivore Spodoptera litura. Two plant species (cabbage and tomato) were inoculated with PGPMs (a fungus and bacteria). The leaves of plants treated with PGPMs were collected to feed third-instar larvae of S. litura and to assess the plant nutrient and defensive compounds. The results indicated that the PGPM application exerted various influences on the foliar nutrient and anti-nutrient compounds and affected the relative growth rate of S. litura. In summary, applying PGPMs might individually affect the induced responses and cause specific interactions. However, this study only provided partial evidence regarding this interaction effect; additional studies are required to clarify the effects of PGPMs on plant defense responses and subsequent insect herbivores.
