This study was conducted to determine the effect of seedling and division nursery stock size on the growth and yield of Wasabia japonica cultivated with cold water from Soyang Dam. As seedling and division nursery stock size were enlarged, their growth and yield were higher. In the case of division nursery stock, the rhizome yield per 10a were 782kg for large one, 723kg form medium one and 567kg for small one, and commercial rates - the percentage of rhizomes that weigh over 40g - were 87% for large one,80% for medium one and 55% for small one. In the case of seedling, large one brought out yield of 575kg/10a while medium and small one brought out low yield of 408kg/10a, and 421kg/10a, respectively. And the commercial rates from seedling were 60% for large one. 13% for medium one and 20% for small one.

The purpose of this study was to investigate the relationship of the head posture with the tone and stiffness of the cervical extensor muscles. Eighty adults in their twenties were chosen as subjects, and the tone and stiffness of the cervical extensor muscles were measured, with their usual head posture in the sagittal plane. For the measured head posture, the craniovertebral angle (CVA), craniorotation angle (CRA), and forward shoulder angle (FSA) were analyzed using Image J. It was observed that the tone and stiffness of the upper trapezius muscle increased significantly with a decrease in the CVA as well as with an increase in the CRA (p < 0.05). As a result of further classification into the normal and forward head postures based on the CVA of the subjects, the forward head posture was characterized by a significant increase in the tone and stiffness of the upper trapezius muscle (p<.05). The results of this study are expected to be used as basic data for the evaluation of the forward head posture and posture education in clinical practice.

This study was conducted to investigate correlation between external factors of chicory root and chicon fresh weight, whereby, to provide basic information of external yardstick of producing standardized chicon. For correlation between external factors (root diameter, root weight) of chicory root and chicon fresh weight were highly correlated. The relationship between external factors (root diameter, root weight) of chicory root and chicon fresh weight, root diameter was strongly affecting chicon fresh weight due to significant at its regression coefficient ($6.06^{***}$). In order to verity this correlation, the root diameter (x) of chicory that were 3 different varieties were based on the 4 different root diameter treatments, such as x ${\leq}$ 30 mm, 30 < x ${\leq}$ 40 mm, 40 < x ${\leq}$ 50 mm and x > 50 mm. The chicon production increased as root diameter increased and the chicon fresh weight, chicon width, and the number of leaves increased as well. Therefore, the measure of root diameter of chicory instead of the internal factors (carbohydrate, and so on.) can be used to predict the chicon fresh weight.

Phenolic compound contents and scavenging activity on DPPH and ABTS radicals in twelve fern species were studied by analysing ultrasonification extraction of dried aerial parts and rhizomes using methanol solvent. Total polyphenol content ranged from 2.97 to 140.1 mg per 1 g dried sample and 0.80 to $49.58\;mg{\cdot}g^{-1}$ fresh sample. Highest polyphenol content was obtained with aerial part of Davallia mariesii and Polystichum lepidocaulon. Total flavonoid content of dried sample was $2.56{\sim}34.91\;mg{\cdot}g^{-1}$ and fresh sample $0.71{\sim}11.49\;mg{\cdot}g^{-1}$. Higher flavonoids were obtained with dried aerial part of Dryopteris crassirhizoma, but with fresh aerial part of P. lepidocaulon. In general, total polyphenol content was higher in rhizomes, except in case of total flavonoid. Scavenging effects on DPPH and ABTS radicals was higher with rhizome extracts compared to aerial parts. The rhizome of Polystichum polyblepharum showed highest effects on both radicals. However, the amount of fresh sample for $RC_{50}$ with consideration of water content and extraction yield. P. lepidocaulon aerial part was more advantageous than P. polyblepharum rhizome. All the fern extracts except for the Coniogramme japonica extract demonstrated superior scavenging effects on ABTS radicals, being similar activity of ascorbic acid and BHT.

This study was conducted to examine characteristics of rhizome growth and flowering of white lotus (Nelumbo nucifera) plant in Muan Hoesan-lake for collecting the basic data on the cultivation and the flowering which is growing in Muan Hoesan-lake of Jeonnam province in Korea. We have planted from the seeds and the enlarged rhizomes of the white lotus which were planted in the plastic containers on April 20 and May 4, 2008, and cultivated under rain shelter condition. Rhizome growth pattern and the flowering characteristics of the white lotus were examined on September 4, 2008. Main rhizomes of the white lotus propagated by the seeds and the enlarged rhizomes were branched by 10% and 15%, respectively. Numbers of nodes in the bloomed and non-bloomed rhizomes of the white lotus were over 14 and below 11, respectively. Flower was not observed in the white lotus when propagated with seeds, however, flowers came out up to 80% by the enlarged rhizomes. First flowers were bloomed from the late July and to the early August, and the number of flowers were 4.0~4.4. The first flower stalks without branching of the main rhizome were emerged in 8.8th node, however, that with branching were 8.0th node. Time to flowering from the emergence of flower stalk on the above-ground parts were required 16 days. White flowers from the lotus were 15.3 cm in height and 28.2 cm in width, their longevity was 3.3 days and the averaged flower fresh weight was 29.2 g. The results conclude that optimum number of nodes on the main rhizomes for blooming the white lotus flowers should be over 8 nodes before the rhizome enlargement.

Ninety-four collections of domestic ginger were evaluated for plant hight, leaf number, stem number, leaf length and width, rhizome yield per plant revealed good variability in stem number and rhizome yield per plant. Moderate variation was observed in plant hight, leaf number, leaf length, leaf width and stem diameter. Rhizome yield per plant was positively correlated with six characters, and leaf number, plant height and stem diameter were positive significant correlation with rhizome yield per plant. Path coefficient analysis indicated that stem number, followed by leaf number, stem diameter, had maximum direct effects on rhizome yield per plant. Maximum indirect effect was observed in case of plant height through leaf number. The indirect effects of leaf length and leaf width through leaf number, and plant height, leaf length and leaf width through stem diameter were also observed. From the selection point of view, the characters like plant height, stem number and leaf number per clump may be considered suitable in choosing a good genotype.

In 1998, there was heavy precipitation of 60 days with amount of 1,042mm from June to September in Andong. Upland crop was severely injured by excessive moisture(EM) on poor drainage field. In this trial, effects of EM on the growth characteristics and yield in Peucedanum japonicum Thunberct and Rehmannia glutinosa Liboschitz was investigated. In Peucedanum japonicum Thunberct, growth of root was decreased more severely than that of aerial part by EM injury, and fresh weight of root per ha was decreased by $21{\sim}80%$ at different degree of EM injury compared to that of normal growth. In Rehmannia glutinosa Liboschitz, percent of withered plant was $10{\sim}52%$ at different degree of EM injury. and rhizome's number per plant and diameter was extremely decreased by EM injury. Fresh weight of rhizomes per ha was decreased by $19{\sim}83%$ at different degree of EM injury compared to that of normal growth.
