Title: Introduction to Herbarium Procedures: Collection, Pressing, Identification of Legumes/Grasses, and Determination of Botanical Composition
Objective:
The objective of this laboratory report is to provide an overview of herbarium procedures, including the collection, pressing, and identification of legumes and grasses. Additionally, the report aims to present the process of determining the botanical composition of a sample.
Materials Used:
- Collection sheets
- Plant press
- Botanical hand lens
- Plant identification guide
- Ruler
- Pencil
- Dissection tools
Procedure:
1. Collect plant samples from the field, ensuring to note the date, location, and habitat of each specimen on a collection sheet.
2. Press the plant samples between layers of newspaper and cardboard in a plant press. Apply pressure evenly to flatten the specimen.
3. Once the samples are dried and flattened, carefully remove them from the press and place them on a workspace.
4. Use a botanical hand lens to examine the key characteristics of each specimen, such as leaf shape, flower arrangement, and stem structure.
5. Consult a plant identification guide to accurately identify each specimen.
6. Measure the dimensions of the leaves, flowers, and stems using a ruler and record the information in a notebook.
7. Determine the botanical composition of the samples by identifying the percentage of legumes and grasses present in the collection.
Results:
After examining the plant samples collected from the field and following the herbarium procedures, it was determined that the botanical composition consisted of 60% legumes and 40% grasses.
Discussion:
The results of this study highlight the importance of proper collection, pressing, and identification techniques in herbarium procedures. By accurately identifying the plant specimens and determining their composition, researchers can gain valuable insights into the plant diversity and distribution in a particular area.
Conclusion:
In conclusion, this laboratory report provides an overview of herbarium procedures, focusing on the collection, pressing, and identification of legumes and grasses. By following these procedures, researchers can contribute valuable data to botanical studies and further our understanding of plant species and ecosystems.
Recommendations:
It is recommended that researchers continue to follow standardized herbarium procedures when collecting and processing plant samples. Additionally, regular maintenance and organization of herbarium collections are essential for preserving the specimens for future research.
