Responses of rotation-resistant and rotation-susceptible populations of the western corn rootworm to transgenic corn expressing cry toxins and validation of a damage function for corn rootworm larvae
… corn expressing one or more Bt toxins—a single-plant bioassay was used. Corn plants were infested with 225 near-hatch eggs at the V5 growth stage (five leaf collar). Larvae were allowed to develop undisturbed on the root systems for 17 d, after which they were recovered using Berlese funnels. …

Small stem assay for chestnut blight resistance in segregating half-sib and full-sib families of F2 and backcross hybrid chestnut trees
… The 2017 trial recorded the day on which the plant wilted, during both the 2017 and 2018 trial, canker length was measured and recorded. The 2017 trial gave insight to the rate at which different seed types wilted and the 2018 trial selected the very best of the F2s.
