The genetic diversity and relationships among plants belonging to the subfamily Sedoideae (Crassulaceae), some of which are indigenous to Korea or introduced from other countries, were determined using chloroplast (cp) nucleotide sequence analysis. To analyze genetic diversity and variation among 19 plants including species belonging to Sedum, Hylotelephium, and Phedimus, the tRNA-Leucine gene (trnL [UAA]) and adjoining spacer in chloroplast DNA (cpDNA) were sequenced and compared across species. Species were divided into two main groups based on the cpDNA sequence comparison. The generated phylogeny indicated that many native Sedum species had diverged from S. album. Members of the Phedimus and Hylotelephium species, and several Sedum species analyzed here, clustered distinctively in different groups. Using cpDNA sequence analysis, we successfully discriminated Sedoideae plants cultivated in Korea from each other, even at the intraspecific level, and the results were reflective of the morphological and biogeographical characteristics. These findings could be useful for classifying samples for proper naming, choosing breeding materials for new cultivars, or identifying species for conservation of horticultural crop resources.

The aims of this study were to examine the effects of different temperatures on seed germination and initial long-day (LD) or short-day (SD) duration on growth, floral initiation, and development of Hosta yingeri S.B.Jones. The germination percentage of H. yingeri seeds was > 90% at 5°C and between 15°C–30°C. The lowest time to the first germination (TFG) and the mean germination time (MGT) were observed at around 30°C. The optimum temperature for germination can be around 30°C considering the final germination percentage, TFG, and MGT together. Plant height, number of leaves, and leaf length increased as the initial SD duration decreased. The percentages of plant bearing buds were 50%, 50%, 20%, 10%, and 0% when the initial SD treatments were 0, 3, 6, 9, and 12 weeks with 29, 26, 23, 20, and 17 weeks of LDs, respectively. No plants flowered when they were exposed to the initial LD conditions. Flower spike length, number of visible buds, and number of open flowers increased as the duration of the initial SD decreased. Four-week-old H. yingeri required ≥ 26 weeks of LD duration to achieve >50% flowering.
