Abstract

The manuscript presents the review of the impact of dormancy, seed storage, and pathogens on seed quality of perennial grasses and forage legumes. The outcomes of earlier studies to enhance the germination of seeds from these species are listed. Numerous studies around the world show that seed dormancy, environmental conditions, storage time after seed harvest, and the presence of pathogens on seeds, affecting the reduction of seed quality of these two groups of plants. This article discusses the possibility to partially or fully controlling impact of different factors on seed quality. Tests and experience of the presence of pathogens (especially Fusarium spp.) indicates a small percentage of infected seed of perennial grasses and legumes, which would not justify the cost of fungicides during seed processing. By applying the optimal concentration of acid in the seed, in combination with the time of exposure, it is possible to improve seed germination for more than 25% in forage grasses and legumes. Similar effects on the increase seed germination of both groups of plants can be achieving by optimal temperature treatments. Mechanical damage to the seed coat on the seeds of these crops can potentially increase germination, but new approaches are also being investigated.
