ABSTRACT
The seeds were studied to know their seedling growth of forages preserved during 9 years, 15 years and 23 years. The experimental period was the autumn in the year of 2006. The results were as follows; alfalfa or lucerne (Medicago sativa L.) only, among the forages produced on the year of 1983 and lived 23 years in a glass-bottle, appeared their seedlings. White clover (Trifolium repens L.) and sorghum (Sorghum bicolor (L.) Moench), produced on 1991 and lived 15 years in a vinyl (plastic) bag, showed their seedling growth. Sorghum Sudangrass hybrid (Sorghum bicolor x S. sudanense), birdsfoot trefoil (Lotus corniculatus L.) and white clover, produced on 1997 and lived for 9 years in Petri-dish, developed their seedlings. It is considered that the three species: white clover, sorghum hybrid and alfalfa or lucerne have the longest longevity among the investigated forage seeds by the current experiment.
