Technical Abstract: Plant metabolites from one organism can affect the germination and development of other plant organisms. The purpose of this experiment was to determine the effect of kenaf (Hibiscus cannabinus L.) leaf, bark, and core extracts on seed germination. Three concentrations (66.7, 33.3, and 16.7 g L-1) of extracts were prepared for each plant component. The leaf, bark, and core extracts were applied to the germination medium for seeds of cucumber, green bean, tomato, Italian ryegrass, and redroot pigweed. Kenaf leaf extracts adversely affected germination of cucumber, tomato, Italian ryegrass, and redroot pigweed. When averaged across all plant components, germination for cucumber, tomato, Italian ryegrass, and redroot pigweed decreased as the extract concentration increased. This data suggests that the detrimental effects of kenaf extracts are dependent on the seed species tested and the plant component applied.
