영문 초록

The present study aimed to understand the variation in seed germination according to the storage period after harvest in the accessions of cultivated and weedy types of Perilla species in Korea. In this milieu, we investigated the germination rate and germination energy of 59 Perilla accessions (15 cultivated var. frutescens type I, 4 cultivated var. frutescens type II, 20 weedy var. frutescens, and 20 weedy var. crispa), which were harvested in autumn 2016. The accessions of cultivated var. frutescens (type I) showed an average germination rate of 80.8% 6 months after harvest; however, the accessions of weedy var. frutescens and var. crispa showed an average germination rate of 0.9% and 8.7%, respectively. Furthermore, the accessions of cultivated var. frutescens (type II) showed an average germination rate of 18.2%. The accessions of cultivated var. frutescens (type I) showed an average germination energy of 75.8%, while the accessions of weedy var. frutescens and var. crispa showed an average germination energy of 0.6% and 6.9%, respectively. In addition, the accessions of cultivated var. frutescens (type II) showed an average germination energy of 14.3%. The germination rate and germination energy for the accessions of cultivated and weedy types of Perilla species increased marginally at 2 months from the first month after harvest. However, it did not significantly increase until six months after that. According to our results, there are two types of cultivated var. frutescens, namely, type I, which showed high germination rate and germination energy, and type II, which showed low germination rate and germination energy. The results of this study will provide basic information to understand variations in the germination of seeds during 6 months of storage period after harvest in the accessions of cultivated and weedy types of Perilla species in Korea.
