Glyphosate application time for sod-seeding orchardgrass establishment in pasture infested with horsenettle (Solanum carolinense L.).

Inbreeding in horsenettle (Solanum carolinense) alters night-time volatile emissions that guide oviposition by Manduca sexta moths.

Plant volatiles serve as key foraging and oviposition cues for insect herbivores as well as their natural enemies, but little is known about how genetic variation within plant populations influences volatile-mediated interactions among plants and insects. Here, we explore how inbred and outbred plants from three maternal families of the native weed horsenettle (Solanum carolinense) vary in the ...

Review of factors determining legumes sod-seeding outcome during pasture renovation in North America

Pasture renovation entails introduction of desirable forage species, usually legumes such as red clover (Trifolium pratense L.), white clover (Trifolium repens L.) or birdsfoot trefoil (Lotus corniculatus L.), into a grass dominated pasture. A commonly used method of pasture renovation consists in drilling seeds into the grass sod (sod-seeding). Introduced legumes benefit the pasture in three w...

Establishment of Cowpeas in a Bermudagrass Sod

The role of male flowers in andromonoecious species: energetic costs and siring success in Solanum carolinense L.

Two non-mutually exclusive hypotheses regarding the benefits of andromonoecy (producing perfect and female-sterile flowers on the same plant) are tested using Solanum carolinense. Results indicate that (1) staminate flowers are cheaper to produce than perfect flowers, even after correcting for their relative position in the inflorescence; (2) the resources saved by producing staminate flowers a...

Inbreeding Depression in Solanum carolinense (Solanaceae) under Field Conditions and Implications for Mating System Evolution

The clonal weed Solanum carolinense exhibits plasticity in the strength of its self-incompatibility (SI) system and suffers low levels of inbreeding depression (δ) in the greenhouse. We planted one inbred and one outbred plant from each of eight maternal plants in a ring (replicated twice) and monitored clonal growth, herbivory, and reproduction over two years. Per ramet δ was estimated to be 0...
