“…However, the results of the experiments where coated seeds were in contact with soil provided even more positive effects. Hakl et al [70] warned that low quality of the coating may even represent a risk for a reduced emergence in the field. According to [71], the adoption of highly artificial and controlled conditions during experimentation raises issues about how to interpret these "in vitro" experiments.…”

Seed treatments have a potential to improve seed performance traits and consequently optimize crop establishment. However, there is a lack of systematic research for these techniques in lucerne, especially under field conditions. The goal of this study was to investigate the potential of various seed treatments on the improvement of lucerne germination and emergence under lab conditions and early seedling growth in the field. Compared treatments were heat treatment; seed priming with water, potassium permanganate, chitosan, vermitea, or bokashi juice; and seed coating with cinnamon, gypsum, wood ash, tannin quebracho, and cocoa powder. Among the seed priming methods, potassium permanganate and chitosan provided the best results in the improvement of seedling length or emergence dynamics, whilst coating with bentonite and gypsum could be recommended for having a positive impact on root development. Cinnamon powder significantly improved the emergence dynamics, seedling, and shoot length. The combination of priming and coating methods seems to be the most effective when assessed under the field conditions, where some positive response in root traits can be evaluated.

“…pretense One to three months of storage in the classic conditions. [61,62] The seeds of perennial forage legumes (alfalfa, red clover, sainfoin, birdsfoot trefoil) are characterized by the presence of a high percentage of hard (dormant) seed after harvesting [51][52][53][54][55]58,95]. The reason for this is a hard seed coat that is impermeable to water and gases [17].…”

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.
