The bioassay showed significant (P < 0.001) increase in the number of roots per cutting when they were treated with Rygex and Ecoryg at the three highest test concentrations (Table 5), indicating that these products are rich in auxin-like activity.
For basement air concentrations, the relative odds of having a resident with a positive bioassay became significant only when the maximum air concentrations exceeded 25 μg/m (OR = 8.8; 95% CI, 1.0 77.2).
In the greenhouse bioassay there were significant differences of total biomass with soil treatment (F3,72 = 27.79, P < 0.001), between plant species (F1,72 = 4.60, P = 0.04) and a significant interaction effect (F1,72 = 3.96, P = 0.01).
Despite the difference in groups, this in vitro bioassay showed a significant reduction in the mean egg development output after exposure to concentrations of the active compounds 3d and 3f.
All these solvent constituents, necessary for good bioassay performance, cause significant ionization suppression in ESI MS. In several cases, the phosphate buffer in a bioassay can be easily replaced by volatile and MS-compatible alternatives, for example ammonium formate or ammonium acetate solutions (pH between 6 and 7.5).
Exposing mosquitoes to detoxification enzymes inhibitors prior to bioassays induced a significant increased susceptibility of mosquitoes to insecticides, revealing the presence of metabolic-based resistance mechanisms.
Bioassays showed a significant resistance ratio for all the natural populations treated with Bti compared with the reference susceptible Bora-Bora strain (no overlap of the LC50 and LC95 95% fiducial limits, and 95% CI of RR50 and RR95 were > 1).
Bioassay data showed a significant reduction in the time required for all HearNPV recombinants to kill second instar H. armigera larvae.
At the end of the bioassay there were no significant differences in growth rate in shrimps fed on the four mixed diets and diet 100F (k = 0.215 0.224).
The mouse skin bioassay demonstrated that with significant inhibition of the pyrosynthesis of alkylated and non-alkylated polynuclear aromatic hydrocarbons, the tumorigenicity of the "tar" will also decrease significantly.
