Lab Report: Allelopathic Effect of Garlic (Allium sativum) on Radish Seeds (Raphanus sativum) Student’s Name Institution Abstract Allelopathy is a process in which one species negatively affect the germination of another species within its proximity by releasing a chemical that suppress growth and germination. The primary aim of this report is determine whether garlic (Allium sativum) has an effect on the germination of radish seeds (Raphanus sativus). The report seeks the answer the question on whether the aromatic biomolecules that garlic produce affect the germination of radish seeds. The method employed in this experiment involves setting up two experimental and two control groups. The experimental group has both garlic and radish seeds while the control group has only radish seeds. The major result of the experiment indicates fewer germination of seeds in the experimental group and more germination in the control group. The study found that garlic has negative to repeat the experiment several times to make the result totally reliable. Secondly it could be possible that other factors could have impacted the germination other than the factors in the experiment. For example the when the seeds were inevitably rearranged on the filter paper during measurements which could have impacted the quality of germination. If possible such an experiment should be allocated more time and be carried out under accurate conditions. References Bais H. P. Vepachedu R. Gilroy S. Callaway R. M. & Vivanco J. M. (2003).
