Rubus coreanus has been used as a traditional medicine in Asia because of its various pharmacological properties. This study examined the effects of protocatechuic acid (PCA), one of phenolic compounds derived from R. coreanus on the lipid metabolism in high cholesterol diet-induced mice. A total of 30 male C57BL/6 mice were divided into 5 groups with 6 mice in each group as follows: (1) Control mice received normal diet (ND). (2) Mice received high-cholesterol diet (HCD) plus water, 10% sucrose solution and treated daily oral phosphate-buffered-saline (PBS) of equal volumes through gavage. (3) Mice received HCD and treated daily with 25 mg/kg b.w./day of PCA (4) with 50 mg/kg b.w./day or (5) with 10 mg/kg b.w./day of simvastatin via oral gavage for 12 weeks. Body weights were measured weekly for a period of experiment. After treatment, liver, thymus, spleen and kidney were harvested and weighed, and the lipid metabolite profiles (total cholesterol, triglyceride (TG), HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c) and liver-damaging markers (GOT and GPT) in serum were examined. PCA significantly reduced the total cholesterol, TG, LDL-c level and increased the HDL-c level. PCA administration also significantly reduced the levels of GOT and GPT. These results indicate that the PCA could be used as a functional material for lowering lipid and an adjuvant for the treatment of hyperlipemia.

Nutritional composition, including total phenolics, tannins and nutrient components, of acorns of Q. actissima, Q. serrata, Q. variabilis and Q. mongolica were analyzed. Acorns were collected from each tree species, which were grown in a seed orchard. Contents of both total phenolics and tannins in acorns of Q. serrata were higher than those of Q. actissima (p<0.05). Interestingly, Q. serrata contained the highest amount of water soluble tannins (71 mg/g dw) and the lowest levels of water insoluble tannins (8.1 mg/g dw) among 4 oak species, resulting that acorns of Q. serrata had the lowest proportion of insoluble tannins. Among 4 oak species tested, Q. mongolicav acorns contained the highest levels of both total dietary fiber (TDF) and ascorbic acid, while the content of beta-carotene in Q. mongolicav was 52-fold lower than that in Q. variabilis (
). Our result showed that nutritional composition of acoms was significantly different between oak species, indicating that tastes or nutritional values might be different as well among major oak species in Korea.

Near infrared reflectance spectroscopy (NIRS) is a rapid and accurate analytical method for determining the composition of agricultural products and feeds. This study was conducted to measure baicalin, baicalein, and wogonin contents in Scutellaria baicalensis by using NIRS system. Total 63 samples previously were analyzed by HPLC, which showed baicalin, baicalein, and wogonin contents ranging 4.56 to 13.59%, 0.28 to 5.54%, and 0.50 to 1.63% with an average of 9.66%, 2.09% and 0.52%, respectively. Each sample was scanned by NIRS and calculated for calibration and validation equation. A calibration equation calculated by modified partial least squares(MPLS) regression technique was developed in which the coefficient of determination for baicalin, baicalein, and wogonin content was 0.958, 0.944, and 0.709, respectively. Each calibration equation was applied to validation set that was performed with the remaining samples not included in the calibration set, which showed high positive correlation both in baicalin and baicalein content file. In case of wogonin, the prediction model was needed more accuracy because of low
value in validation set. These results demonstrate that the developed NIRS equation can be practically used as a rapid screening method for quantification of baicalin and baicalein contents in Scutellaria baicalensis.

. P. multifida was cultivated for 12 weeks. The results of study, Calcium arsenate treatment showed slightly decreased growth of P. multifida. But, growth of P. multifida cultivated in the remaining arsenic treatment was similar to untreated control plot. With only short-term cultivation of 4 weeks, aerial part of P. multifida in Sodium arsenate treatment showed high arsenic accumulation of
. The arsenic accumulation (
) was the highest at 12 week. On the other hand, underground part showed the highest arsenic accumulation in Potassium arsenite treatment (
) and Calcium arsenate treatment accumulated
of arsenic. Regardless of arsenic types, aerial part of P. multifida was absorbed more than
of arsenic. And removal of arsenic in soil was also higher. Therefore, Pteris multida is considered to be suitable phytoremediation meterial of various arsenic contaminated areas.

DOI : 10.7732/kjpr.2014.27.4.354
Field study was conducted to evaluate the agronomic effectiveness of sulphur-bentonite fertilizer. Soil pH was slightly lower tendency to the increase of sulphur-bentonite fertilization, but did not indicate a sharp decline in soil pH. The T-N contents in the
plot was higher to 700 mg/kg and the organic matter content was 1.29% in the
plot. The content of available-P was also increased to 289 mg/kg in the
plot. The growth characteristics of the young radish (Raphanus sativus L.) has significantly more in
plot on upper part, and more on under part in
plot. Therefore, it is concluded that the application of sulphur-bentonite fertilizer was thought to be effective for the chemical characteristics of soil and crop growth enhancement.

This text was experimented and investigated the optimum production time and germination characteristic of Fabaceae plant seed that collect in Korean Chungnam. Optimum time of seed production was early-mid October of Chamaecrista nomame, early November of Lespedeza cuneata and early-mid November of Lespedeza bicolor. Epiphytic amount of seed full ripe was the most times in early October of Chamaecrista nomame, early November of Lespedeza cuneata and Lespedeza bicolor, respectively. Seed rate of maturity was the highest times in early November of Chamaecrista nomame, mid November of Lespedeza cuneata and Lespedeza bicolor, respectively. Germination rate by seed collection time was the highest times in early October of Chamaecrista nomame (99.8%), mid November of Lespedeza cuneata (68.3%) and early November of Lespedeza bicolor (24.3%). Germination days by seed production time was the shortest times in mid October of Chamaecrista nomame, mid November of Lespedeza cuneata and Lespedeza bicolor, respectively. Optimum temperature of germination was
in Chamaecrista nomame,
in Lespedeza cuneata, and Lespedeza bicolor was difficult judgment of germination optimum temperature because of low germinating rate.

Korean Journal of Plant Resources, volume 27, issue 4, 2014, Pages 371~379
DOI : 10.7732/kjpr.2014.27.4.371
In order to determine the response of turnip leaves to various races of Botrytis cinerea, fourteen different races were infected to the leaf surface and measured the lesion size. Based on lesion size of the pathogen on the leaves, turnip showed susceptible response to four races, moderate to seven races and resistant to three races. Four glucosinolate (GLS) compounds, such as butenyl GLS, indole-3ylmethyl GLS (I3M), 4-methoxy-indole-3-ylmethyl GLS (4MOI3M) and normal methoxy-indole-3ylmethyl GLS (NMOI3M) were identified in turnip leaves infected with Botrytis cinerea. Leaves infected with resistant races showed higher GLS contents as compared with the leaves infected with susceptible races. Contents of I3M in the leaves with resistant races were 2.5 times as high as those in uninfected leaves, whereas I3M in the leaves with susceptible races showed lower contents than those in untreated leaves. Leaves infected with resistant races showed 4MOI3M and NMOI3M contents 2.3 and 2.7 times as high as those in uninfected leaves, respectively. GLSs in the infected leaves were most abundant at 5~10 mm area from center of the lesion. However, the GLSs in 5~10 mm area were rapidly degradated at leaves with susceptible races which resulted in continuous expansion of the lesion on the leaves, whereas no degradation was obseveved at leaves with resistant races. These results suggest that accumulation and degradation of GLS compounds in turnip leaves closely related to the susceptibility and resistance of turnip leaves to Botrytis races.

Plants as well as crops are damaged by a combination of the hot and dry winds that has been a major factor in the reduction of crop production. A means to protect them from damaging conditions is to consider a coating material. In this study, we established laboratory screening methods to find a coating material to protect a crop from rapid transpiration caused by various factors. In a test measuring the weight loss of kidney bean seedlings for 6 days, Avion treatments decreased its weight loss (P=0.05). Owing to long-time spend in completing this assay, we performed a more simple method using a cobalt chloride paper strip, which changes from blue to red colors under water condition. Beewax, guagum, paraffin liquid, soybean oil, and PE-635 gave a waterproofing effect above 37 and 43% at 0.5 and 1 h after treatment, respectively. However, these tested materials did not show significant waterproofing results at 2 h. Although the methods produced reasonable results, a screening method to obtain more objective data is needed. An alternative is to use an instrument that can detect the transpiration of crop leaves. In a preliminary test using barley leaves, a portable photosynthesis system showed transpiration inhibition of 2% soybean oil and 10 times-diluted Avion under field conditions. In another test using the leaves of maize seedlings and apricot tree, 2% liquid paraffin and plant oils such as apricot oil, linseed oil, olive oil, and soybean oil showed significant transpiration inhibition (P=0.05). Especially, paraffin liquid and soybean oil selected from above tests gave good transpiration inhibitory effects against rice at 2%. In addition, the mixture of 2% soybean oil and a spreader showed more elevated inhibition results comparing with soybean oil or the spreader alone indicating that the spreader may be attributed to more uniform diffusion of the hydrophobic material onto the leaf surface of maize seedlings. The hydrophobic material coated physically the stomata and cuticle layers on leaf surfaces of rice. These hydrophobic materials screened in this study are expected to be used as plant coating materials.

Plant senescence is one of the survival strategies to use limited nutrients efficiently during growth, development and adaptation. In this study, we isolated a gene (PagSEN1) homologous to SENESCENCE 1 from Populus alba
P. glandulosa. The PagSEN1 gene encodes a putative protein consisting of 243 amino acids containing a rhodanese domain. Southern blot analysis suggested that two copies of the PagSEN1 gene are present in the poplar genome. We characterized its transcriptional expression under various conditions mimicking senescence and environmental stresses. The PagSEN1 was expressed most strongly in mature leaves but most weakly in roots. The gene was significantly up-regulated by treatments with mannitol, NaCl, ABA and JA, but not by cold, SA and GA3. These results indicate that PagSEN1 is involved in senescence response induced by environmental stresses.
