GB/T 2930 "grass seed inspection procedures" is divided into 11 parts.
--- GB/T 2930.1 Grass seed testing procedures sample;
--- GB/T 2930.2 Grass seed testing procedures Clarity analysis;
--- GB/T 2930.3 grass seeds test procedures Determination of other plant seeds;
--- GB/T 2930.4 grass seed testing procedures sprout test;
--- GB/T 2930.5 grass seed testing procedures biochemical (tetrazolium) determination of viability;

This section GB/T 2930 Part 7.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 2930.7-2001 "forage seed test species and species identification." This section and GB/T 2930.7-
2001 compared to the main technical changes other than editorial changes are as follows.
--- The standard name from the "forage seed test species and identification of species" changed its name to "grass seed test species and species determination"
(See cover,.2001 edition cover);
--- In the foreword, the drafting rules (see the preamble) on which the standard compilation is based have been added; statements of the nature of the appendix have been deleted (see.2001 edition
The foreword);
--- Removed "ISTA Preface" (see the.2001 edition of the ISTA Preface);
--- Removed "test purpose" (2001 version of Chapter 3);
--- Added "Physical Specimens" and "Reference Specimens" to "Terms and Definitions" (see 3.4 and 3.5);
--- In the "principle" adds "the determination of specific traits" (see 4.3);
--- Modify the "test sample" weight requirements (see 6.1 and Table 1,.2001 version 7.1 and Table 1);
--- Increase the "seed determination" and "seedling determination" in the "method of determination" of the standard method name (see 6.2.2 and 6.3.2);
--- Added "test sample" in "Field Plant Determination" (see 6.5.1);
--- Calculation and presentation of "seeds, seedlings and plants" in "Calculation and Representation of Results" (see 7.1,.2001 edition 8.1);
--- Added "species and species determination method" (see Chapter 8);
--- Added "Morphometric Determination" Sudan grass species morphology "and" Medicago and Agropyron seeds fluorescence determination "content
[See 8.1.1d) and see 8.1.1f)];
--- Added "the authenticity of corn varieties and hybrid purity ultrathin layer isoelectric focusing electrophoresis (UTLIEF) Determination of" content
(See 8.1.5);
--- In the "seedling determination method" added "Beet hypodermic determination" (see 8.2.2);
--- In the "seedling determination method" adds "alfalfa and koji seedlings molecular determination method" (see 8.2.5);
--- In the "seedling determination method" adds "Sudan grass and sorghum seed molecular determination method" (see 8.2.6).
This section uses the redrafted law to amend the use of International Seed Testing Association (InternationalSeedestingAssociation,
ISTA) Chapter 8 Seed Species and Varieties Determination (Edition.2012).
This section and the ISTA "International Seeds Inspection Regulations Chapter 8. Determination of species and varieties" (2012 version) compared to more structural adjustment
The entire Appendix A lists this section with the ISTA "International Seeds Inspection Regulations Chapter 8. Species and Varieties Determination" (2012 version) of the Chapter
Control list (see Table A.1).
This section and the ISTA "International Seeds Inspection Regulations Chapter 8. Determination of species and varieties" (2012 version) there are technical differences, which
The provisions involved in these differences have been marked by a vertical single line (|) at the margin of the outer margin, and the corresponding technique is given in Appendix B
List of technical differences and their causes (see Table B.1).
