Plenty of variations in nutritional, morphological and agronomic traits occur in the pigmented rice germplasm. The current study was conducted to evaluate the growth characteristics of 71 pigmented rice genotypes having different origin taking one Korean landrace (Heugjinjubyeo) as control. Amongst the twenty eight growth characters studied; leaf length, leaf width, ligule length, panicle length and panicles per hill showed a higher degree of variance. The heading dates of the pigmented rice germ plasm were distributed from Aug. 1 to Sep. 28. Thirty five cultivars that headed or flowered in August were found adaptable for cultivation in Korea. The mean culm length and panicle length were significantly higher than Heugjinjubyeo but most of cultivars having strong or middle of culm strength made it possible to produce the stable yield. Some cultivars showed unique qualitative characters such as openness of culm angle, purple ligule, auricle, awn and glume colors, poor panicle exsertion and long empty glume. Nine cultivars including Heugjinjubyeo showed purple seed coat color while those of the others (62 cultivars) were of red seed coat.

<P>As a material of current interest compatible with many living organisms, carbon has received considerable attention for applications in medicine. To improve and investigate the performance and applications of diamond-like carbon (DLC) films for implantable bio-organs, it is important to optimize the synthesis process from the original deposition conditions to control the characterization of DLC. Simultaneously, it is necessary to develop new techniques and processes that yield DLC films with stronger adhesion to the substrate and better biocompatibility. This work investigates the suitability of sputtering plasmas for application of carbon film biocompatibility in cell growth. This work also reports an approach to the study of the biomedical response of the well-characterized carbon films deposited by a DC unbalanced magnetron sputtering system (UBMS). Conductive carbon films are prepared at a working pressure of 3 mTorr, and their properties are studied under different operating conditions by varying the target power density. In the present work, we have used L-929 cells as the biomaterial. The influence of L-929 cells on the carbon films fabricated using closed field UBMS is studied. The data reveal that the change in L-929 cell growth with 1-5 day's proliferation is caused by the decreasing electrical resistivity with increasing sp<SUP>2</SUP> bonding structure.</P>
Antioxidant potential of grains of exotic rice germ plasm

Significant variations occur in pigmented rice germplasm with respect to their antioxidant potential. Therefore this study was designed to evaluate the antioxidant potential of exotic rice germplasm collected from different parts of the globe. Grain samples of exotic rice germ plasm (21 0 accessions) were collected from different countries of Asia, America and Europe and their ground grain samples were extracted with 80% methanol at 30 oc using sonicater for 30 minutes to estimate their total polyphenol and flavonoids contents and antioxidant activity. Rice germplasm had tremendous variations with respect to total polyphenols (0.0800.71 mg g- 1) and falvonoid contents (0.091 00.413 mg g" 1 ) and antioxidant activity (18096%). Rice cultivars with red and black seed coat had higher antioxidant activity owing to significantly higher polyphenols and falvonoid contents in their grains. Therefore rice cultivars with red and black seed coat color should be included in breeding rice genotypes with higher nutritional value.
