GOST 12038-84 PDF

Full title and description

GOST 12038‑84 — Семена сельскохозяйственных культур. Методы определения всхожести (English title: Agricultural seeds. Methods for determination of germination). National (USSR / Russian) state standard that specifies laboratory methods and procedural rules for determining germination, germination energy and related sowing quality indicators of seeds of agricultural crops (excludes sugar beet, flower seeds and cotton where otherwise noted).

Abstract

This standard defines accepted procedures for sampling, preparing and testing seeds to determine germination capacity and germination energy under controlled conditions. It sets out test substrates, temperature and moisture regimes, counting intervals, calculation methods and reporting requirements so results are comparable between laboratories and useful for seed producers, certification bodies and research organizations. The standard has been issued as GOST 12038‑84 and maintained with subsequent amendments.

General information

• Status: In force (maintained with amendments).
• Publication date: Designation year 1984; introduced into effect 1 July 1986 (with later corrections and amendments, including amendments registered in 1988, 1991, 1995 and a correction entry in 2016).
• Publisher: Standards publishing of the USSR (Izdatel'stvo standartov) / national standards body (later maintained under Russian standards catalogues).
• ICS / categories: Agriculture — Plant production; common classifier entry 65.020 (plant growing / seeds) often cited as 65.020.20 in national catalogs.
• Edition / version: GOST 12038‑84 (original 1984 text, effective 1986) with integrated amendments and corrections (amendments Nos. 1 and 2 and later editorial updates).
• Number of pages: ~30–31 pages depending on printed/reissued edition.

Scope

Applies to seeds of agricultural crops except where explicitly excluded (notably sugar beet, many flower species and cotton are covered by separate standards). The standard establishes laboratory germination test methods (including germination energy) used to assess sowing quality of seed lots for certification, production quality control and research. It covers sample sizes, test substrates, environmental conditions, recording intervals and calculation/reporting of germination results.

Key topics and requirements

• Definition of germination terms (germination, germination energy, abnormal seedlings, dead seeds).
• Sampling and representative sample preparation for laboratory tests.
• Approved test media and substrates (e.g., rolled paper, substrate types) and preparation instructions.
• Prescribed environmental conditions: temperature regimes, humidity control, light/dark requirements and duration of tests for different crop groups.
• Counting schedules (timing for determining germination energy and final germination) and criteria for viable seedlings.
• Calculation methods for percent germination and germination energy; presentation and required content of test reports.
• Requirements for repeating tests, handling of abnormal seedlings and adjustments for pre‑treatments or dormancy‑breaking when specified.

Typical use and users

Used by seed testing laboratories, seed certification agencies, seed producers and exporters/importers, agricultural research institutes and university laboratories. Typical applications include routine quality control of seed lots, official certification testing, research experiments where standardized germination assessment is required, and verification of treatment effects (e.g., priming, irradiation, chemical treatments).

Related standards

Replaces or updates procedures in older national documents on seed germination (for example earlier national GOST versions such as GOST 12038‑66 in part). It is used alongside numerous normative references that address related test tools and materials (water quality, thermometers, laboratory containers) and other seed standards; for some specific crops or seed types parts of its scope have later been covered by separate standards (for example some seed groups have complementary GOST documents). Typical referenced standards include national GOSTs on water for laboratory use, thermometers and other testing aids, and later crop‑specific seed standards.

FAQ

Q: What is this standard?

A: GOST 12038‑84 is a national standard that prescribes laboratory methods for determining germination and germination energy of seeds of agricultural crops.

Q: What does it cover?

A: It covers sample preparation, test substrates and conditions (temperature, moisture, light), counting intervals, criteria for viable seedlings and calculation/reporting of germination results. It excludes certain crops that are handled by separate standards (notably sugar beet, many flower species and cotton).

Q: Who typically uses it?

A: Seed testing laboratories, certification bodies, seed producers, agricultural research institutions and university labs use it for routine quality control, certification testing and comparative research.

Q: Is it current or superseded?

A: The standard GOST 12038‑84 is maintained in national catalogs and has been kept in force with amendments and corrections; some parts of its scope for specific seed groups have later been complemented or replaced by more specific standards. Check the applicable national standards catalog for the latest status for a particular crop or jurisdiction.

Q: Is it part of a series?

A: It is one of a suite of seed and sowing quality standards used in national practice (other GOSTs and crop‑specific standards address related seed quality parameters and test methods). It continues the traditions of earlier seed‑testing GOSTs and is cross‑referenced with other normative documents covering laboratory equipment and related seed standards.

Q: What are the key keywords?

A: Seeds, germination, germination energy, seed testing, agricultural crops, seed quality, certification, laboratory methods.
