|
This study was conducted to identify the optimum condition for dehydration and storage for maintaining the seed vigor in pelleted carrot seeds. The water content of solid materials of un-pelleted seeds was 4.9% (F.W. basis), and that of pelleted seeds was 24%. When we dehydrated pelleted seeds for 3 hr at 25℃, 35℃, and 45℃, all seeds were dehydrated to 5% - the same level of water content as that before pelleting. Pelleted seeds did not show any significant difference in germination from un-pelleted seeds, and neither was there any significant time or germination difference between pelleted and un-pelleted seeds at the tested dehydration temperatures. However, the T50 value of pelleted seeds increased about 3 days larger than that of un-pelleted seeds. Germination speed of pelleted seeds in which the dehydration period was prolonged at 45℃ was delayed compared to those prolonged at 25℃ or 35℃ for the same period. The optimum dehydration condition, which could be applied for large scale in the industry, was dehydration at 35℃ for 3 hr, and the optimum storage temperature which could maintain the seed performance was 5℃.
