Champ d’application

This standard is applicable to the breeding and sales of one-year-old apple nursery plants. It covers various types of apple seedlings, including vigorous stock, dwarf interstock, and self-rooting dwarfstock apple plants. It is mandatory for all manufacturers and sellers involved in the apple nursery trade in China. The standard does not apply to multi-year-old or non-grafted apple plants.

Exigences techniques

The standard classifies apple nursery plants into three grades based on comprehensive morphological and physiological parameters. It specifies basic requirements regarding the purity of variety and rootstock, absence of quarantine targets, and overall health without severe diseases, pests, or mechanical damage. Key technical parameters include the quantity and dimensions of lateral roots, the length of the rootstock and interstock, and the height and diameter of the nursery plant. The standard also sets limits on the gradient (inclination angle) and the number of plump buds within the shaping strip. Additionally, specific requirements are established for virus-free nursery plants, which must not carry specified viruses such as apple mosaic virus and apple stem pitting virus. Manufacturers must ensure that all grading parameters strictly adhere to the defined thresholds for each grade.

Méthodes d’essai

Inspection involves random sampling based on batch size, with specific sampling rates defined for different quantities. Measurements are conducted using tools like vernier calipers for diameters and rulers for lengths. Quarantine inspections follow the procedures outlined in GB 8370 and GB 15569. For virus-free plants, virus detection is executed according to NY 329. Any batch with more than 5% unqualified seedlings is deemed non-compliant.
