Salicylic Acid Response To Simulated Herbivory In Geographically Distinct T. Heterophylla And H. Discolor Populations, Amy E. Castle May 2021

Salicylic Acid Response To Simulated Herbivory In Geographically Distinct T. Heterophylla And H. Discolor Populations, Amy E. Castle

Honors Projects

It is commonly known that plants may produce salicylic acid as a chemical defense response to wounding, although the phenomenon has usually been observed with regard to insect herbivory. Stem and leaf tissue of two species, Tsuga heterophylla and Holodiscus discolor, which are often eaten by deer, were extracted in methanol and analyzed by HPLC to quantify salicylic acid concentration in experimentally wounded or control samples. No salicylic acid response was detectable in T. heterophylla, suggesting it is a less useful candidate species for future study. Some but not all H. discolorsamples had a measurable salicylic acid …


Effects Of Flower Color On Pollination And Seed Production In Lupinus Perennis, Amanda Morris May 2020

Effects Of Flower Color On Pollination And Seed Production In Lupinus Perennis, Amanda Morris

Honors Projects

We examined how flower color morphs (blue vs white) in Lupinus perennis affect the probability of a flower setting fruit, average mass of a seed produced, and average number of seeds per pod.


Vegetative Rapid Assessment And Habitat Quality Analysis Of Steidtmann Woods, Sarah Mae Bail May 2017

Vegetative Rapid Assessment And Habitat Quality Analysis Of Steidtmann Woods, Sarah Mae Bail

Honors Projects

Due to invasive species and the assumption of an unhealthy ecosystem, Steidtmann Woods is an underutilized piece of land owned by Bowling Green State University. However, the property had never been analyzed. The proposed hypothesis was that Steidtmann was indeed in destress and its ecosystem could benefit from intervention—removal of invasive species and supplementation of natives. Through a rapid vegetative analysis, data was collected in several regions of the woods to identify what navies and non-natives were present as well as to identify their proportions. With that data, the species evenness, richness, and diversity was calculated; first, with raw field …
