Poster #1 Allelopathic Effects of Juglans nigra on Seed Germination and Growth Kristen Aaker Faculty Mentor: Robin Richardson Allelopatic plants are territorial in that they inhibit growth, reproduction and survival in other plants. I chose to work wuth Juglans nigra or the Eastern Black Walnut, which typically grows in central and eastern parts of the United States. The walnut produces a toxin known to most plants as juglone. This study was focused on the magnitude of the allelopathic effect of juglone on germination and growth of various perennials and a fruit tree. I chose two perennials, digitalis and fennel, and one fruit, apple. They were planted and watered using a Juglans nigra solution. I measured seed germination and true leaf growth. Germination rate and growth will demonstrate the allelopathic effect of these species. Further work with Juglans nigra could decipher the usefulness of allelochemicals in or for controlling unwanted plants. |
