Storage possibility of the pimed soybean seed (Glycine max (L.) Merr.)

In the technology production, various seed enhancement procedures are often applied to improve the quality of the seed, in particular germination and other properties of the seed after the treatment. Seed priming is the method used by the Old Greeks. Today it is a cheap and simple presowing measure that is primarily used in developing countries. However, the biggest problem in applying this measure is the length of storage of the primed seed. Storage possibility of the primed soybean seed was determined by a temperature of 25 °C during the period of 90 days. Th e soybean seed was primed with KNO3 (1%), ASA (100mgl-1) and KCl (1%) solutions, and then stored in paper bags, and its quality is tested every 15 days. The results showed that the reduction in the quality of the primed seed is considerably faster than the no-primed. Primed soybean seed can be stored at a temperature of 25 °C during 60 days after immersion, and after that period the significant reduction in its quality can occurs. After 75 days of immersion germination energy was reduced by 60.33% and germination by 9.33%, while after 90 days the germination energy reduction was 68.33% and germination by 65%. One of the causes for reducing seed quality is an increase in MDA content, especially after 75 and 90 days of storage. Also, the free proline concentration has been reduced while the content of vitamin C increased after 15 days primarily in seeds immersed in ASA and KCl solutions, and after 45 days its content was reduced
