Korean Journal of Plant Resources, volume 22, issue 2, 2009, Pages 111~115
The seeds of Phellodendron amurense have difficulty to obtain because these plants show dioecism with independent distributions. This experiment was conducted to find the effects of soaking and prechilling treatment on the germination of P. amurense seeds. Seeds were soaked for 3, 5 and 10 days (soaking treatment), and placed on petri-dish at
for 10, 20, 30 and 50 days after soaked at room temperature for 24 hours (prechilling treatment). After the treatments, germination percentage, mean germination time, germination speed and germination performance index were analyzed. As a result of sowing, prechilled seeds for 30 days had the highest percent of germination, whereas all of the soaked seeds showed lower percent of germination than non-treatment (control). In case of mean germination time, only prechilling for 30 days was more effective than control. In germination speed, all of the soaked seeds had lower values than control whereas all prechilled seeds except prechilled seeds for 20 days showed higher values than control. Especially prechilled seeds for 30 days showed the highest rate among the prechilling treatments. Germination performance index was similar to germination speed.

Heteropappus arenarius Kitam., an autumn-flowering biennial belonging to wild chrysanthemums, is found to be native in southeastern coastal area and Jeju island of Korea. It could play a good role for ground cover plants on a large-scale landscape area, especially, barren soil or sloping hillside. This study was initiated to screen optimum germination temperature influenced by local strain and harvesting stage of H. arenarius. The following was the response of seed germination between local strain and temperature. The average of final germination percentage (FG) was the highest in 'Guryongpo' (89.7%) among four local strains, followed by 'Gujwa' (87.3%), 'Gampo' (87.3%), and 'HKNU-I' (71.5%). The average of
was shorter in 'Gujwa' (3.6 d) and 'Guryongpo' (4.0 d) than the others. The average of FG and
was the highest as 76.2% and shortest as 3.6 d in
, respectively, followed by
. In case of 'Gujwa', however, FG and T50 was higher in
and shorter in
than others. In the relationship between harvesting stage and temperature, the average of FG was greatly higher in Stage III (90.7%) and Stage IV (88.6%) than the others including Stage II (35.7%) and Stage I (26.0%). The average of
was shorter in Stage IV (3.7 d) and Stage III (4.3 d) than the others, which showed less than 50% of FG. Nevertheless, the available range of seed harvesting stage was from Stage I to Stage IV because H. arenarius seeds could germinate at all stages. In conclusion, it was recommended that the optimum temperature and harvesting stage was
, respectively, for seed germination of H. arenarius.

In this study, the selected 789 lines having agronomic values out of over 2,500 mungbean (Vigna radiata (L.) Wilczek) germplasms, examined the 27 characters including hypocotyl color and leaf size of 401 lines in 2005 and of 388 lines in 2006, and analyzed the contents of vitexin and isovitexin in these mungbean germplasms. The average contents of vitexin and isovitexin in mungbean of the 401 lines used in 2005 were 8.71(
) and 9.54(
) mg/g, respectively, and the correlation coefficiency (
) of the contents of vitexin and isovitexin was 0.958. Nine lines including VC3890B were selected to be the ones containing high vitexin and isovitexin. The average contents of vitexin and isovitexin in mungbean of the 388 lines used in 2006 were 10.17(
) and 10.64(
) mg/g, respectively, and the correlation coefficiency (
) of the contents of vitexin and isovitexin was 0.958. Six lines including VC4096-2B-4-B-2-B were selected to be the ones containing high vitexin and isovitexin. The contents of vitexin and isovitexin were higher in the mungbean with larger leaves and longer ripening period out of the main characters.

Germination tests on 3 species that have potential for use as sprout vegetables, such as Coreopsis tinctoria, Saussurea pulchella, and Matricaria recutica, were conducted for 20 days under different temperatures of
, and conditions of light and dark. C. tinctoria showed germination of 83% under
and dark condition after 4 days, S. pulchella 51.7% under
and light condition after 20 days, and M. recutica 90.3% under
and dark condition after 4 days. To investigate optimum plantlet size before greening treatment, seeds germinated were allowed to grow under darkness. The optimum growth of C. tinctoria was obtained under
after 5 days, S. pulchella under
after 6 days, and M. recutica under
after 6 days. Greening treatment resulted in diminished longitudinal growth, but C. tinctoria and S. pulchella showed more vigorous latitudinal growth. Days required before marketing as sprout vegetables were different according to species - Three days of greening was good for C. tinctoria, 2 for S. pulchella, no greening for M. recutica. Generally, tightly sealed containers for minimum water loss were recommended for storage of sprout vegetables after harvest. However, storage methods for each species were different depending on various factors like temperature of storage, presence of ventilation holes of storage packages and forms of marketing. More detailed research for above 3 species is proposed.

We performed RAPD analysis to investigate the inter-/intraspecific relationships and regional variations of Phragmites japonica and P. communis according to the environmental change. One hundred and fourty nine genetic effective polymorphic bands between 300 bp and 1,900 bp were marked from RAPD PCR with nine oligoprimers. From the RAPD analysis by Nei-Li's genetic distance, the dissimilarity indices among the populations of Phragmites japonica were relatively low from 0.012 to 0.061, and Phragmites communis were also low from 0.033 to 0.095. It showed the close genetic relationships among the same species populations, and both species were distinctly independent with relatively high level of dissimilarity indices (0.043 - 0.132). The obvious genetic markers to distinguish two species were confirmed and those profiles were suggested. From the UPGMA phenogram by RAPD analysis, both species showed the water environment related cluster patterns by distributional regions. RAPD analysis was useful to delimit two species taxonomically and to investigate the genetic relationships among inter-/intraspecific populations.
