Other claims from this paper (10)
- Observation Three peanut stilbene phytoalexins inhibited Aspergillus flavus spore germination at ED50 values of 4.9–12.8 micrograms ml-1.
- Observation The peanut phytoalexins inhibited Aspergillus flavus hyphal extension at ED50 values of 4.9–12.8 micrograms ml-1.
- Association Peanut phytoalexin yield varied with cultivar, incubation conditions and duration, and crop history.
- Observation Ten peanut cultivars yielded 28 to 935 micrograms per g fresh weight of phytoalexin after slicing and incubation.
- Association The peanut phytoalexin yield and Aspergillus flavus colonization correlation was absent after 96 hours of incubation.
- Intervention effect Incubation in water reduced peanut phytoalexin yield.
- Intervention effect Incubation at 37 degrees C reduced peanut phytoalexin yield.
- Intervention effect Nitrogen gas incubation prevented peanut phytoalexin production.
- Intervention effect Freezing before aerobic incubation prevented peanut phytoalexin production.
- Intervention effect Pod-development drought reduced peanut phytoalexin yields by 17–65% relative to non-stressed controls.
