简介：
Overview
This article presents a software-based image analysis system designed to study the morphology of stoloniferous and rhizomatous species. The protocol allows for the measurement of stolon and rhizome length and diameter, applicable to samples with significant biomass.
Key Study Components
Area of Science
- Plant morphology
- Image analysis techniques
- Crop science
Background
- Understanding the growth and morphology of stolons and rhizomes is crucial for various crops.
- Current methods primarily rely on weight measurements, limiting analysis.
- This study introduces a method that enhances measurement accuracy.
- It focuses on species such as turfgrasses, meadows, and pastures.
Purpose of Study
- To provide an alternative method for measuring stolon and rhizome morphology.
- To facilitate analysis of samples with large biomass.
- To improve understanding of plant growth dynamics.
Methods Used
- Collection of samples using soil core samplers or frames.
- Cleaning samples using sieves and water streams.
- Scanning samples with WinRHIZO standard equipment.
- Measuring dry weight after drying samples at 105 degrees Celsius.
Main Results
- Significant differences in stolon length density among different Bermudagrass cultivars.
- Patriot cultivar showed the highest rhizome length density.
- Stolon length density increased over the study period for the Patriot cultivar.
- Rhizome density varied seasonally, with peaks in July.
Conclusions
- The method allows for precise measurement of stolons and rhizomes.
- It enhances the understanding of plant morphology in relation to biomass.
- Careful sample selection and cleaning are critical for accurate analysis.
