Seed Quality and Microorganisms
2020A high germination percentage and vigor level are two very important characteristics of high-quality seeds (Thomson, 1979). Unfortunately for agriculture and horticulture, seed germination and vigor can be markedly reduced by a number of factors, including the action of microorganisms (i.e., bacteria and fungi), viruses, and nematodes.

Farmer’s seed sources and seed quality: 2. seed health
2013The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were found on wheat samples: Cochliobolus sativum, Fusarium avenaceum, F. graminearum, F. nivale, F. poae and Septoria nodorum.

Outlook on Agriculture, 1978
Fungal organisms developing in grain in store lead to hot spots and increased moisture content. Uncontrolled, deterioration is rapid, resulting in loss of viability in grain for seed, and off-flavours which render it unfit for milling and malting. Under certain conditions substances may be produced which are toxic to man and animals.

Seed is functionally defined as a reproductive unit, in contrast with grain that is fed to animals or used directly or indirectly as a food or in food products. Although the harvested propagule is the same, unlike grain the seed must be alive and capable of producing a seedling.

Seed Science Research, 1998
AbstractGrowers expect high-quality, genetically pure seed. As a result, seed companies maintain quality control programmes that monitor seed from harvest to purchase. An array of ‘traditional’ seed quality tests, including mechanical tests and tests of genetic purity, seed germination and vigour, and seed health tests, is used, and seed quality ...

Seed quality and alternative seed delivery systems.
2009AbstractThis chapter on lentil covers the following: factors determining seed quality (seed genetic purity, physical purity, germination, vigour and health), factors affecting seed quality (genetic factors, production environments, harvesting and mechanical damage), seed treatments (seed priming, Rhizobium inoculation, and chemical treatments ...
