- To establish a foundation for official seed testing specifications.
- To ensure the genetic purity and viability of C. officinalis seeds.
Summary:
- Optimal methods for purity analysis (8g sample, 20-mesh sieve), authenticity testing (phenotypic observation, size measurement), seed health (PDA medium, 28°C, 5 days), 1000-seed weight (500-seed method), water content (133°C, 3 hours), viability (0.1% TTC, 3 hours), and germination (pleated paper, 25°C, 2-9 days) were determined.
- These methods provide a standardized approach to assessing Cyathula officinalis seed quality.
- The study outlines specific parameters and procedures for each test.
Impact:
- Provides a basis for establishing official seed testing specifications for Cyathula officinalis.
- Aids in ensuring the quality and efficacy of medicinal products derived from C. officinalis.
- Facilitates consistent and reliable seed sourcing for cultivation and research.
