Alcance y aplicabilidad

This standard is applicable to the grading, classification, and inspection of ginseng seeds utilized in agricultural production, scientific research, and commercial operations. It is strictly designed for the ginseng planting industry and does not apply to other agricultural seeds. It establishes the mandatory benchmarks for seed quality evaluation, including parameters like thousand-grain weight and seed viability.

Requisitos técnicos

The standard specifies the physical and chemical requirements for ginseng seeds, categorizing them into three primary grades based on thousand-grain weight, plumpness, purity, viability, and moisture content. Seeds must exhibit normal color and odor, be free from diseased grains, and must not exceed a one-year storage limit. The technical requirements also outline specific agricultural practices for seed selection, flower thinning, field management, harvesting, washing, and drying to ensure optimal seed quality. Furthermore, the standard mandates that substandard seeds outside the minimum grade thresholds are strictly prohibited from use.

Métodos de ensayo

The standard outlines a comprehensive suite of laboratory testing procedures to evaluate seed quality. Key tests include purity determination using a two-sample average method, moisture content analysis via an oven-drying method at 105°C, and viability testing using biochemical stains such as tetrazolium red and indigo carmine. Additionally, it details procedures for measuring thousand-grain weight, bulk density (using a 61-71 type or 51 type volumeter), plumpness, maturity, and disease inspection through visual and cross-sectional examination.
