Other claims from this paper (10)
- Intervention effect One-percent gypsophila saponins increased the lag phase of bacterial growth.
- Intervention effect Gypsophila saponins did not modify clover biomass.
- Intervention effect Gypsophila saponins significantly increased adhering soil weight, twofold at 1%.
- Intervention effect One-percent saponins induced qualitative and quantitative differences in dominant Gram-negative clover rhizosphere strains.
- Intervention effect Saponins made Chryseomonas spp. undetectable or significantly decreased its population in clover rhizosphere.
- Intervention effect Saponins made Acinetobacter spp. undetectable or significantly decreased its population in clover rhizosphere.
- Intervention effect Aquaspirillum dispar increased with saponin addition in clover rhizosphere.
- Intervention effect Aquaspirillum spp. became the major clover rhizosphere genus with saponin addition.
- Observation Aquaspirillum dispar and Aquaspirillum spp. dominated the Gypsophila paniculata rhizosphere.
- Mechanism The authors suggest that saponins may control soil rhizosphere bacteria through rhizodeposition.
