Flowery Knotweed Root is the dried tuberous root of the knotweed family wheres Auriculate Swallowwort Root is the dried tuberous root of the swallowort family. Flowery Knotweed Root is also called Red Flowery Knotweed Root in China, which is dried root of Polygonum multiflorum THUMB. Chinese Flowery Knotweed Root is better known as the dried tuberous root belonging to the family Apocynaceae whereas White Flowery Knotweed Root in Korea is the dried tuberous root of Cynanchum wilfordii(Maxim) Hemsl. Up to now, while the dried root named Red Flowery Knotweed Root has been widely used in China, Auriculate Swallowwort Root has been widely used in Korea. Both the roots contrast in a striking way with the origin, shape, botanical names, other names, and chemical constituents, so administration and dosage without discrimination of both sides can be open to question. According to the literature, it is recorded that Flowery Knotweed Root and Auriculate Swallowwort Root are similar to the characteristics, properties, and actions. From this study, the result is as follows: 1. Flowery Knotweed Root and Auriculate Swallowwort Root are divided into the family Apocynaceae and the family Polygonaceae, respectively. Accordingly 2. Flowery Knotweed Root is in shape of an irregular spindle and looks reddish- brown or deep reddish-brown and the section is light yellowish-brown, while Auriculate Swallowwort Root looks yellowish-brown and the section is white or yellow. 3. Flowery Knotweed Root is reported by the Journal of the Crude Drug that the medicinals have not the same therapeutic action as Auriculate Swallowwort Root. It is recorded that the properties, channel entry, functions of Flowery Knotweed Root and Auriculate Swallowwort Root in literature have much in common. Many works on the roots of this plant has been used traditionally as a tonic are required of. In view of the results, Flowery Knotweed Root and Auriculate Swallowwort Root varies both in nature and in shape, so that the administration and dosage of the medicinals must be taken a prudent attitude.

In order to survey possibility to produce saikosaponin from in vitro hairy root culture, culture of callus, adventitous root, and hairy root of Bupleurum falcatum L. were estabilished, and quantitative and qualitative aspects in saikosaponin extracted from these were compared with those of cultivated root. Callus grew well in MS medium containing 0.9 $\mu$M 2, 4-D. In contrast, both of adventitous root and hairy root grew well in hormone-free MS medium. However, hairy root showed more rapid growth with extensive lateral root branches, characteristics of lower content of water and softer than in adventitous root. Among the selected lines of adventitous root and hairy root were observed difference in the growth rate. Mannopine, one of opine synthesized in the transformed tissue with Agrobacterium rhizogenes. A4 were detected in the extract of hairy root lines. Pattern and content of crude saponin from adventitous and hairy root showed no difference, but somewhat difference from those of cultivated root. However, in callus, distinct production-aspect of saponin was not observed.

Six-year-old ginseng roots were divided into rhizome, main root (epidermis, cortex and xylem) and lateral root (big tail root, mid tail root and fine tail root) and the concentration levels of soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) in each part of the ginseng were investigated. The amount ratios of SDF to IDF (SDF/IDF) in various parts of the ginseng root were also compared. The concentration levels of SDF and IDF in the ginseng root were 6.56% and 15.41 %, respectively, where the level of SDF in main root was a little higher than that of lateral root. However the amount of IDF in main root was lower than that of lateral root. The SDF/IDF was highest in main root, 0.513, which was higher than that of lateral root or rhizome. The SDF/IDF was 0.704 in xylem, 0.478 in cortex, and 0.099 in epidermis of the main root and the SDF/IDF was 0.576 in big tail root, 0.463 in mid tail root, and 0.255 in fine tail root of the lateral root. It has been reported that SDF might have preventive effects on diabetes, obesity, high blood pressure, colon and rectum cancers, while IDF might have preventive effects on constipation. Therefore, main root of six-year- old ginseng root is thought to have a little different physiological activity from lateral or fine tail roots.

This study was carried out to investigate the correlation between root diameter and ginsenoside composition of Panax ginseng C. A. Meyer cultivar Yunpoong. Dry matter ratio of main root was a little higher than that of lateral root and fine root, and that was higher by the increase of root diameter in the same root parts. Total ginsenosides composition of main and lateral roots increased by the decrease of root diameter, especially in lateral root. Similar resulted in fine root, but there was no significant difference where root diameter was below 2.5 mm. Except for ginsenoside-$Rg_1$, other ginsenosides component, PDs, PTs and total ginsenosides had highly negative correlation with the root diameter within whole root, main root+lateral root and lateral root+fine root, while $Rg_1$ had positive correlation with the root diameter.

The thirty six mandibular second molars, which were extracted because of hopeless tooth due to advanced periodontal disease, were measured the length of mesial and distal root and the distance from cementoenamel junction to root separation. The molars were cross-sectioned every 1.5 milimeter from cementoenamel junction to root apex perpendicular to long axis and each section was photographed, projected and measured with a calibrated Digital Curvi-Meter(Com Curvi-8. Japan). The root surface area (RSA), percentage of the RSA and the linear variation of the RSA were calibrated for each 1. 5 mm section. The results were as follows. 1. The mean length of the roots was 12. 98mm for mesial root, 11.84 mm for distal root. The mesial root was longer than distal root.(p<0.01) 2. The mean distance from the cementoenamel junction to the point at which the root separate from the root trunk was 3.82mm for the buccal furcation and 4.75mm for lingual furcation. The buccal root separation was coronal than the lingual root separation.(p<0.01) 3. The total root surface area was $317.78mm^2$. 4. The mean surface area of the root trunk was $150.06mm^2$ and averaged 42.54% of the total root surface area. 5. The mean root surface area was $88.79\;mm^2$ for the mesial root, $78.93mm^2$ for distal root, The mesial root surface area was wider than the distal root surface area.(p<0.05) 6. In comparision, the mean root trunk surface area of the mandibular 2nd molar was wider than that of mandibular 1st molar(p<0.01), but each root of 2nd molar was smaller than that of 1st molar(p<0.01).

Assessment of root weight grade system for the numeral definition in Korea ginseng was tried by investigation of 13 boxes of the 15-root-grade of 4-year-old white ginseng as a model. In this case satisfaction to theoretical value was 58% in root weight and 50% in root number. The coefficient of variation (CV) was high (35%) for individual root weight in package. The CV of tap root weight 1 among package is low (7.1%) even though there was no significant correlation between tap root weight : and lateral root weight among roots. The mean percentage of tap root to root weight in each package ranged 61 to 74% with CV range of 16.5 to 33.2%. The CV was not much different between 1st and 2nd lateral root weight and the means was above 60%. Strict practice of numeral definition of root weight grade system will be prerequisite for chemical standardization of Korea ginseng.

The successful restoration program requires a comprehensive understanding of variables influencing seedling efficiency. Below-ground is hypothesized to have a major impact on seedling performance of species when planted in agriculture, and degraded areas with different types of mulching. This study investigated on Sg. Terla Forest Reserve in Cameron Highlands Pahang, Malaysia. In this study randomized complete block design (RCBD) was used. The excavation method was applied to study the root system development, above, and below ground biomass distributions under different types of mulching: coconut mulching (CM), oil palm mulching (OM), plastic mulching (PM) and control (CK). The root diameter, main root length, lateral root length, root coiling, and root direction toward to sun were recorded. The results in this study indicate that mulching had significant effect on root diameter, main root length, and root distributions among treatments while for lateral root length, root: shoot ratio, dry biomass distributions, and above and below ground biomass did not showed significant effect among treatments. The highest values for root diameter, lateral root length, main root length, root distributions, dry biomass distributions and above and below ground biomass were showed in CM treatments. However 75% of root coiling was observed in seedlings between treatments.

To investigate the depth of the root concavity and root surface area of the maxillary first premolar, 40 maxillary first premolars were used. All the teeth which extracted because of advanced periodontal disease and orthodontic treatment procedure, were sectioned every 1.5mm from cementoenameljunction to the apex with hard tissue microtome. Each sectioned root was taken photograph with slide film, and projected for measuring with a calibrated digital Curvi-Meter. The root surface area, percentage of the RSA and the linear variation of the RSA were calibrated for each 1.5mm section. Linear variation of the depth of root concavity was measured on mesial and distal root surface for each section using computer-aided digitizer. The results were as follows. 1. The total mean root length of maxillary first premolar was 13.48mm. Mean buccal root length of 2-rooted tooth was 12.59mm, mean palatal root length was 12.73mm, and mean root length of single rooted tooth was 13.78mm. 2. The total mean root surface area of maxillary first premolar was $194.17mm^2$, mean root surface area for 2-rooted tooth was $205.97mm^2$ and mean root surface area for single rooted tooth was $188.49mm^2$. 3. It was 59.93% of the total root surface area that the area from CEJ to coronal 6mm. And, the coronal half of the root length accounted for approximately 71.76% of the total root surface area. 4. Most deepest concavity of the mesial root surface was 0.65mm at apical 3.0mm, 4.5mm level in maxillary first premolar. And, that of the distal root surface was 0.37mm at apical 4.5mm level. 5. All of the maxillary first premolar had mesial root surface concavity. This mesial root surface concavity appeared to be more pronounced in 2-rooted tooth than single rooted tooth.
