| Abstract | This study was conducted to survey the germination characteristics of the seeds of Larix kaempferi, which is a major plantation species in Korea, according to the storage period. The germination experiment was conducted at 25°C, targeting seeds collected in 1996, 2004, 2008, 2009, 2010, and 2011. Prior to the germination experiment, seeds were subjected to different soaking treatments for 1, 2, 3, and 7 days including non-treatment. The germination rate in L. kaempferi seeds was observed to be higher in those that were collected recently; that is, the seeds that were stored for a shorter period of time. The germination rate of the seeds collected in 2011, which were stored immediately after collection, was 20.7%. The seeds from 1996 and 2004 did not germinate at all. The seeds from the year 2008 showed the lowest germination rate at 2.7%. The whole T50 of the test-subjected seeds was observed to be 3-7 days. Germination uniformity tended to decrease with shorter storage period. Soaking treatment lowered the mean germination time and uniformity, except for the stored seeds (collected in 1996 and 2004), which did not germinate. Based on the results of these experiments, such as a reduction in germination rate according to the seed storage period, it seems likely that more detailed investigations into the changes in seed viability and storage management are needed with respect to L. kaempferi seeds. |
