  • 야생화를 도시환경 조성에 이용하고저 대량 육묘기술 중 알맞는 관수방법과 양액을 구명하기 위하여 꽃향유를 공시하여 시험한 결과 다음과 같았다. 1 2개월 육묘시 저면 양액 담배수 관수 방법이 지상 관수에 비해 10배나 높은 생장량을 보였다(지상관수 자료는 Data에는 보이지 않음). 2. 뿌리발달로 보아 저면 양액 관수방법은 2개월 육묘로도 가능하였지만 지상 관수는 3개월 육묘해야 화단에 정식 할수 있을 것으로 보였다. 3. 2개월 육묘 저면 양액 관수시 양액농도는 1/2S의 Sonneveld 기준액이 가장 좋았고 N, K 는 약간 늘려주는 것이 좋았다. 4. 식물체내 무기물 성분은 저면 양액 관수가 높았고 생장량이 많았던 구가 비교적 높았다. 5. 화단에 정식시켜 개화기의 관상가치는 지상관수나 저면 양액 관수가 별 차이를 보이지 않아 흡비력이 높은 이 야생화는 육묘시는 다소 생장이 떨어져도 화단에서는 대체로 같아졌다. 6. 개화기의 초장도 3/2S와 Hyponex구에서 가장 컸으나 초장은 너무 커서 재배적으로 좀 줄여줘야 더 좋을 것으로 보여 S나 1/2S도 좋을 것으로 생각되었다.

  • Several yeast colonies were isolated from wild flowers collected from East, West and South coast areas of Korea by plating of flower suspensions on the YPD plates containing antibiotics, streptomycin and ampicillin. Polymerase chain reactions (PCR) were performed for the amplification of D1/D2 region of 26S rDNA for those colonies. PCR-amplified nucleotide sequences were compared using BLAST for their identification. As results, 27 yeast strains belonged to 15 species were isolated from wild flowers collected at Donghae, where is located in eastern coast of Korea. Also, 34 strains belonged to 17 species were isolated from wild flowers of Daecheon, where is located in western coast of Korea. In addition, 22 strains belonged to 13 species were isolated from wild flowers collected at Wando, where is located in southern coast of Korea. Among those 45 species isolated from 3 different collection sites, only 4 species including Cryptococcus laurentii, Metschnikowia koreensis, Pseudozyma rugulosa, and Rhodotorula mucilaginosa were found from all 3 different collection sites. And 5 species including Cryptococcus aureus, Cryptococcus flavus, Hanseniaspora uvarum, Pichia guilliermondii, and Rhodosporidium fluviale were overlapped from the at least 2 different collection sites. Other 23 species were found only in a specific collection sites implying that each area has distinctive yeast flora.

  • Various yeasts from wild flowers of Ulleungdo in Gyeongsangbuk-do and Yokjido in Gyeongsangnam-do, Korea were isolated and identified by comparison of nucleotide sequences for PCR-amplified D1/D2 region of 26S rDNA using BLAST. Forty eight yeast strains of twenty two species and sixty yeast strains of twenty five species were isolated from wild flowers of Ulleungdo and Yokjido, respectively. Only seven species were overlapped from the two different islands areas: Cryptococcus albidus, Cryptococcus laurentii, Metschnikowia reukafii, Pichia scolyti, Rhodotorula glutinis, Rhodotorula graminis and Rhodotorula mucilaginosa. Among forty species from two different islands, other thirty three species were restricted to specific collection site suggesting that each area has distinctive yeast flora.

  • We have been experimenting for industrialize four kinds of wildflowers(Smilax china, Saururus chinensis, Houttuynia cordata and Zizania caduciflora) which are used for Korean medicinal plants for a long time as Korean resources plants. Smilax china, Saururus chinensis, Houttuynia cordata was used for roots and Zizania caduciflora used for leaves. Extraction was carried out in 50% ethyl alcohol, which was concentrated by freezing the material and then injected at a low concentration of 100ppm. The results of the study on the antibacterial potential activity and antifungal potential activity using the four wildflowers strains were as follows. 1. The results of the sterilization and antibacterial potential activity and antifungal potential activity were as follows. Houttuynia cordata showed good inhibitory effect for Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa. The inhibitory power of Zizania caduciflora was proved to some extent. However, other cultivars showed little antibacterial and antifungal activity. 2. The antifungal potential activity against Candida albicans, Aspergillus niger, Aspergillus fumigatus, and Cryptococcus neoformans was small but some inhibition against Candida albicans was confirmed. There was no inhibition of other fungi potential at all.

  • Chilean wild flower seeds showed low germination rate and lacked germination uniformity. This experiment was conducted to find out the effects of light conditions, $GA_3$ (50 mg/L, 100 mg/L, 200 mg/L) and $KNO_3$ (0.1%, 0.2%, 0.4%) treatments on germination of five species of Chilean wild flower seeds. The seeds of $Schizanthus$ $candidus$, $Schizanthus$ $hookerii$, and $Schizanthus$ $litoralis$ did not germinated in light condition. The others did not show a significant different germination rate under light and dark conditions. The germination rate of $Mimulus$ $luteus$, $Schizanthus$ $candidus$, $Schizanthus$ $hookerii$ increased 2.3, 5.6, and 3.2 times compared with control, respectively in $GA_3$-200 mg/L treatment, but that of $Rhodophiala$ $ananuca$ enhanced slightly in $GA_3$-50 mg/L treatment. Those results suggested that the germination rate of Chilean wild flower seeds enhanced by $GA_3$ treatment that is very efficient in breaking seed dormancy.
