This study was carried out to induce plant regeneration via multiple shoot formation from sucker explants of Rubus fruticosus L.
R. parvifolius L. To induce adventitious shoots, the sucker explants were sterilized in 1.2% sodium hypochlorite (NaOCl) solution, and then were cultured on the full and 1/2 MS solid medium supplemented with BA (0.1, 0.5, 1.0,
). After 4 weeks of culture, the highest frequency (83.3%) of shoot formation from sucker explants was obtained from the full MS medium with
BA. The highest shoot number (3.7) per explant was obtained from the full MS medium with
BA. After 12 weeks of culture, the number of shoots (15.4) per explant was increased. The highest frequency (95%) of root formation was obtained from the 1/2 MS medium, when the explant with shoot were cultured on the full, 1/2 and 1/4 MS medium. The survival rate of the plantlets after transfer to plastic pots containing sand, soil, and vermiculite (1.1:1, vol.) was 95%. The results indicate that multiple shoot procedure can be applied for an efficient mass propagation of Rubus fruticosus L.
R. parvifolius L.

This study was conducted to compare the antioxidative effects of Dendranthema zawadskii var. latilobum (Maxim.) Kitam and D. zawadskii var. yezoense (Maek.) Y.M. Lee & H.J. Choi due to the harvest date. Harvested samples at May 9th (early), July 17th (middle) and September 3rd (late stage) were extracted with 80% ethanol, and biological activities and antioxidant substance contents were detected. The earlier harvested samples showed the higher moisture contents and extraction yields. DPPH radical scavenging effect of early harvested D. zawadskii var. latilobum (Maxim.) Kitam (
) was similar to BHT (
). ABTS radical scavenging effects of both species harvested at early stage were higher than that of ascorbic acid which was well-known natural antioxidant. However, both species harvested at late stage showed the highest
chelating effect, but it was lower than that of EDTA. Total polyphenol and flavonoid contents of both species were higher when samples were harvested earlier stage. However, both species harvested at early stage contained more total polyphenols (79.93 and
) than flavonoids (57.84 and

Nerine from south africa and its sparkling flower shape make us estimate it as a hopeful kind of cut follow. There was a few studies on Nerine in korea. We started this study to set bulb propagation methods. The propagation by tissue culture was changeable according to the growth regulators The best growth regulator combination which makes a lot of Bulblet was NAA
in Nerine bowdenii ‘Favourite’ and Nerine sarniens ‘Red’ respectively. The adjust culture media source for tissue culture were glucose 9% as a carbon source and (
) 40mM as a nitrogen source. When glucose was used as a carbon source, Bulblet were harvested a little bit low then sucrose but comparative emergence rate was so high that it is good for carbon source in nerine tissue culture. When we consist culture media as MS+BA
+sucose 7% + (
) 40mM, the produced Bulblet were reached up to 1.7 each per bulb and emergence rate was up to 100% irrespective of acclimatization period. The suitable culture explant for nerine tissue culture was scale. When scale was cultured with MS+BA
+sucose 7%, its propagation efficiency was 54 times greater than using growing point. A proper culture part of the scaly leaf was middle part (8 scaly leaf from outer 8th scaly leaf) when middle part was cultured the number of Bulblet were up to 1.8 each per explant.

Korean Journal of Plant Resources, volume 21, issue 2, 2008, Pages 139~143
Enzyme activity and expression of cytochrome P450 gene involved in the pathway of capsidiol biosynthesis were compared in five different solanaceae plants such as red pepper, green pepper, tobacco, potato and egg plant. Base on genomic DNA and/or RT-PCR results, four solanaceae plants such as red pepper, green pepper, tobacco and egg plant possess P450 gene in the genome and specifically expressed by elicitor treatment. However, potato was appeared to have neither P450 nor cyclase gene in the genome. P450 genes did not show any expression in the plants under normal condition, but showed highly specific expression under elicitation condition in various organs and tissue such as leaf, root, stem and culture cells.

This study was conducted to clarify the characteristics of seed germination and to promote the germination rate in Pollia japonica Thunb. that was pointed to protect by the Office of Forestry in 1997. It was better the germination rate and the growth of in the light than those of in the darkness. The seed germination of Pollia japonica showed the highest germination rate at
any other treated temperature. To increase the germination rate of Pollia japonica, it was conducted priming treatments and storage treatments at
. Priming treatments using 1% NaOH, 1% KOH for 30min were effective compared to control, but soaking of 100mg/L GA3 for 24 hours, 1% NaOCl for 30min were not useful. It was higher in wet storage than in dry storage. Wet storage of seeds showed a germination rate with 95.3% in 90-day treatment, which improved 55.3% than dry storage in 90-day.
