Compliance overview
Scope and applicability
This standard applies to the production and sales of mulberry seeds and saplings within the People's Republic of China. It specifically covers common mulberry seeds, hybrid mulberry seeds, common seedlings, hybrid seedlings, grafted saplings, and cutting saplings. It is not applicable to non-mulberry species or ornamental tree varieties. The technical content of this standard is entirely mandatory.
Technical requirements
This standard specifies the minimum quality thresholds for mulberry seeds, focusing on variety purity, cleanliness, germination rate, and moisture content. For seeds, specific minimum limits are established for both common and hybrid categories to ensure basic viability. Any seed lot failing to meet a single specified parameter is deemed unqualified. For mulberry saplings, the standard mandates requirements for seedling diameter, variety purity, root integrity, and visual appearance. Different categories of saplings—such as common, hybrid, grafted, and cutting saplings—have distinct minimum diameter and root length criteria. Saplings are rejected if the proportion of unqualified items exceeds 5.0% of the sampled batch or if variety purity fails to meet the threshold. Additionally, the standard outlines the general requirements for packaging, labeling, and transportation. Seeds should be packaged in cloth bags with specific weight limits, while saplings must be bundled in set quantities. Labels must comply with the relevant general rules for crop seed labeling, and transport conditions must prevent moisture, heat, and physical damage.
Testing methods
Inspection procedures are executed in accordance with GB/T 19177. The standard specifies that variety purity testing for hybrid seeds must be conducted during the seedling growth period. For hybrid seedlings, grafted saplings, and cutting saplings, purity inspections are performed either after lifting (uprooting) or during the growth period. Sampling follows strict batch rules, with seed sampling taken at 0.2% of the total batch weight, and sapling sampling determined by tiered quantities based on the total plant count.
FAQs
What products are regulated under GB 19173-2010?
The standard regulates mulberry seeds (common and hybrid) and saplings (common seedlings, hybrid seedlings, grafted saplings, and cutting saplings) produced and sold within China.
Are there any updates from the previous version of GB 19173-2010?
The 2010 version is a mandatory standard that replaces the 2003 version. Key updates include revised terminology, modified quality requirements for both seeds and various sapling types, updated inspection rules, and the deletion of previous appendices.
How does GB 19173-2010 handle inspection and sampling?
The standard references GB/T 19177 for its detailed inspection procedures. It specifies that purity testing for hybrid seeds must occur during the seedling growth period, while purity tests for hybrid, grafted, and cutting saplings are conducted after lifting or during the growth period.
