Gamma-hydroxybutyrate (GHB) is an illicit drug, which may be derived in plants from a stress-inducible metabolite known as gamma-aminobutyrate. Here, oxygen deficiency caused the accumulation of GHB in green tea and soybean sprouts (76 and 155 nmol g-1 fresh weight, respectively). These findings demonstrate that GHB levels are elevated in severely modified atmospheres, but they pose no risk to human health. Further work is required to assess the extent of this phenomenon.

The study was undertaken with a view to investigate the effects of different basal media and organic extracts on organogenesis of Dendrobium orchid. Protocorm like bodies (PLBs) were cultured in Knudson C (KC), Vacin and Went (VW), half strength Murashige and Skoog (½MS) and New Phalaenopsis (NP) media supplemented with Sabri banana pulp (Sb), Charcoal (C) and Coconut water (Cw) organic extracts. KC, VW, ½MS and NP media significantly influenced the plantlet regeneration of Dendrobium orchid. Among the media, ½MS showed better performance on fresh weight, number PLBs, shoots and leaves per plantlet, The longest shoots were found in KC medium and maximum length of leaves was found in both KC and ½MS media. In case of different organic extracts Sb showed significantly better performance on fresh weights of PLBs, number of shoot and leaves per explant, length of shoots and leaves. Key words: Organogenesis, Dendrobium, media, organic extracts. DOI = 10.3329/jard.v5i1.1454 J Agric Rural Dev 5(1&2), 30-35, June 2007

Seed of four grass species was re-hydrated to 11 pre-determined moisture concentrations ranging from 100 to 600 g kg-1 fresh weight ( FW) to simulate seed maturation during swathing and combining. The performance characteristics of three thermogravimetric and two electronic capacitance methods of moisture determination were evaluated. The thermogravimetric methods had no moisture range limitations and were, in general, more accurate than the electronic methods. The thermogravimetric Koster tester is suitable for grass seeds of all moisture concentrations, and can be easily adapted for use at field sites. The John Deere Moisture- Chek electronic tester is suitable for the rapid determination of moisture in grass seeds but is limited to concentrations of 80–250 g kg-1 FW.

The study was conducted at the USDA Biotechnology Laboratory, Department of Biotechnology, Bangladesh Agricultural University, Mymensingh during May to June 2006 to investigate the effect of different concentrations of IBA (0, 0.5, 1.0, 1.5 and 2.0 mg/l) with Vacin and Went (VW) medium and charcoal on root formation in Dendrobium orchid. Four parameters such as number of roots plantlet-1, length of root, fresh weight of root and days required for root formation were recorded at three DAIs (10, 20 and 30). The use of different concentrations of IBA had significant effects on the parameters examined. The best results were obtained from 1.0 mg/l IBA treatment in which the number of root was 1.81 plantlet-1, length of root 0.35 cm, fresh weight of root 0.16g at 30 DAI and the minimum days to root formation was 10.8.

Four linear furanocoumarins (psoralen, xanthotoxin, isopimpinellin, and bergapten) were identified on the surfaces of callus cells of Ruta graveolens, Ruta pinnata, Daucus carota, and Pastinaca sativa in the concentration range of 0.055 – 1.1 μg total/g fresh weight. In some cases these surface deposits amounted to a substantial percentage of the total, with the highest (67%) in Daucus, but they were not always proportional to the total concentrations in the cells. Variation in the ratios of concentrations of the individual coumarins indicated selective extrusion. An unresolved mixture of isopimpinellin and bergapten, with the former predominating in the proportion of ca. 7:1, was extruded in the highest concentrations on brown callus. Shake cultures produced up to two orders of magnitude more furanocoumarins than callus cells and extrusion was accelerated, but the concentrations of particular exported furanocoumarins varied, again pointing to selective extrusion.

In addition to the contribution of organic textiles to human health to our environment today, it also contributes significantly to our environment. The main ingredient of organic textiles, which is one of the most important elements, is that the drugs used in cotton production are not chemical, but also provide the opportunity to live in a cleaner environment in their creatures living around us. Organic textiles are very important in people's lives and day by day people become aware of organic textiles is a very important phenomenon. On the awareness of people, it is more important that the organ is preferred to clothing today. SPSS (Statistical Package for Socia lSciences) for Windows 22.0 program was used in the analysis of the data obtained in the study. Descriptive statistical methods were used to evaluate the data. Attitude level score was determined as a result of using score values for answers to scale questions. Satisfaction comparisons were made according to gender, age, marital status and education variables. Key Words: Textile, Sunday, Agriculture, Organic
