  • This study was conducted to estimate the days to flowering based on the effective accumulated temperature at various altitudes in the Jiri mountain region and to compare growth and yield characteristics according to the sowing date of safflower (Carthamus tinctorius) four genetic resources (local variety, IT323225, IT333473, and IT333482). The safflower four resources were sown on March 29, May 3, May 13, May 24, and June 2. The days from sowing to flowering of the safflower four resources by sowing dates were in the order of the local variety (61.0 days), IT333482 (73.2 days), IT323225 (74.0 days), and IT333473 (74.2 days). The base temperature and effective accumulated temperature for the days to flowering of the safflower four resources calculated based on the daily mean temperature were local variety 6℃, 579℃, IT323225 11℃, 766℃, IT333473 11℃, 768℃, IT333482 10℃, 750℃, respectively. As a result of applying the calculated effective accumulated temperature and daily mean temperature of the past five years (2019 to 2023) by various altitudes and the different sowing dates (every 15 days from April 1 to August 15), the days to flowering of the safflower four resources decreased from April 1 to July 15 during the sowing date and then tended to increase from August 1. In addition, the days to flowering at various altitudes were investigated in the order of plains, mid-mountain, and mountain regions. Among the yield characteristics, plant height, number of branches, number of capitula, number of seeds, and seed weight decreased as the sowing dates were delayed for the safflower four resources.

  • Background: Planting vigorous cuttings that quickly develop shoots and roots is essential to the biological and economic success of producing medicinal flowers. The present study aimed to evaluate the effect of storage temperature and duration on seedling capacity in the propagation of Chrysanthemum indicum L. and to investigate the effect of rooting media on the growth of C. indicum L. after cutting. Methods and Results: Returning cuttings to supplemental cold storage ($2.0{\pm}1.0^{\circ}C$) may extend duration of cutting viability 6 weeks, returning cuttings to supplemental warm storage ($25.0{\pm}1.0^{\circ}C$) is not recommended. The treatment of the growing media experiments, which were conducted in the 2014 planting seasons, included sawdust, river sand, topsoil + sawdust, topsoil + poultry manure, sawdust + river sand, river sand + poultry manure, topsoil + river sand + poultry manure, topsoil + poultry manure + river sand + sawdust. Result indicated that the topsoil + poultry manure media performed best and supported the highest number of branches (3.47), branch length (26.39), and number of leaves (88.63). Conclusions: The results of the present study suggest that cold storage and the topsoil + poultry manure growth media was superior in supporting the early establishment of C. indicum cutting, this result will have a tremendous influence on propagation of this species.

  • This text was analyzed and investigated the distribution of medicinal plants in Cheongoksan Bonghwagun Korea, in order to search the medicinal resources that are used in modern medicine. Medicinal plants of the Korean Pharmacopoeia (10th edition) distributed in Cheongoksan Bonghwagun were consisted of 93 taxa ; 82 species, 10 varieties, 1 forma of 79 genus, 50 families. In medicinal plants of the Korean Pharmacopoeia, rate of native species and exotic species was 89.2% (83 taxa) and 10.8% (10 taxa) respectively. Family classification was the most of compositae of 8 taxa, and life form classification was most of herb of hemicryptophyte species. The classification by using parts were 34 taxa of root use and the classification of efficacy utilization was 24 taxa of Cheongyeolyak (heat-clearing drug) use.
