Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 21044-2007 "Chinese soft-shelled turtle". Compared with GB/T 21044-2007, except for structural adjustments and editorial changes,
In addition, the main technical changes are as follows.
a) The description of external morphological features has been changed (see 5.1.1~5.1.5, 5.1.1~5.1.5 of the.2007 edition);
b) Added the schematic diagram of the appearance measurement of Chinese soft-shell turtle (see 5.2.1);
c) The scalability characteristics have been changed (see 5.2, 5.2 of the.2007 edition);
d) Added the carapace and plastron plates of Chinese soft-shell turtle (see 5.3.2);
e) replace “reproductive characteristics” with “growth and reproduction” (see Chapter 6, Chapter 6 of the.2007 edition);
f) Changed the karyotype diagram, karyotype formula and arm number of Chinese soft-shell turtle (see 7.1, 7.1 of the.2007 edition);
g) The measured graph and scan graph of lactate dehydrogenase (LDH) isozymes in the muscles of Chinese soft-shell turtle were modified (see 7.2, 7.2 of the.2007 edition);
h) Added molecular genetic characteristics (see 7.3);
i) Added the method for determining the age of Chinese soft-shell turtle (see 8.3.2);
j) Changed the pretreatment method for chromosome preparation (see 8.4.1, 8.2.1 of the.2007 edition);
k) The electrophoretic separation method of isozymes has been changed (see 8.5.6, 8.3.2 of the.2007 edition);
l) Added molecular genetic characterization methods (see 8.6);
m) Changed the inspection rules and result determination rules to determination rules (see Chapter 9, Chapter 9 of the.2007 edition);
n) Added the preparation methods of various isoenzyme reagents (see Appendix A).
