차나무 종자의 발아특성

Abstract

In order to obtain the fundamental data required for increasing seedling population during seed and seedling production, some factors such as germination temperature, chilling duration, seed coat treatment, imbibition duration, and storage method affecting seed germination of tea ( Camellia sinesis) were investigated in the study. As for seed germination temperature of 15, 20, 25, and 30℃, all the three varieties including 'Saemidori', 'Okumidori', and 'Topyung' showed the highest germination percentages at 25℃. Both of 'Saemidori' and 'Okumidori' had higher germination percentage at chilling duration of longer than 50 days than that at 38 days. In the case of naturally dried 'Topyung' seeds, seed coat removal showed 64% of germination percentage which was higher than those of partial seed coat crack and control and seed coat removal in 'Saemidori' had 83.3% of germination percentage which was higher than that of control, 47.5%. In both of 'Yabukita' and 'Okumidori', 2~4 days of imbibition duration indicated higher germination percentages than those of 0~1 day. In seed storage method, as for 'Yabukita' seeds, germination percentage was higher when stored in wetness than in dryness, and as for 'Topyung' and 'Okumidori' seeds, both treatments showed no difference. Germination speeds were higher when stored in wetness for seed of all the three varieties in accordance with increase of seed fresh weight.
