This study investigated the effects of various cultivation pots on Betula platyphylla var. japonica seedlings in order to select suitable pots for the production of healthy seedlings for the ecological revegetation. We used six types of the pots natural pot, natural pot with inside 5 mm width root turning bump, natural pot with inside 10 mm width root turning bump, negative-phototropism pot, negative-phototropism pot with inside 5 mm width root turning bump, and negative-phototropism pot with inside 10 mm width root turning bump. As greenhouse cultivation provided a high level of control of irrigation and temperature, the seedlings did not show any significant differences in plant height, number of branches, and diameter at root collar, but showed a significant difference in root growth among the different types of pots. The root growth was best in the negative-phototropism pot. In the negative-phototropism, the roots grew in a vertical shape, while they grew abnormally in a spiral shape in the natural pots. In outdoor cultivation, the growth of seedlings showed significant differences according to container types. The seedlings grown in specially manufactured negative-phototropism pots were most excellent in all of the height, number of branches, diameter at root collar and root growth. As for the seedlings grown in the negative-phototropism pots, their roots grew vertically and thus their rooting was well established after they were transplanted outdoor. A size of less than 5 mm ridge installed in the negative-phototropism was found to be appropriate for the seedling growth. These results showed that the negative-phototropism pot would be best suitable for the growth of Betula platyphylla var. japonica seedlings and for the production of seedling for ecological revegetation.
In this study, we analyzed the nutrient composition and ${\beta}$-glucan content in Lentinula edodes fruiting bodies from different collection areas. Four types of free sugars were detected by HPLC, and the range of trehalose prevalence was 0.83% to 9%. The highest total amino acid content was observed from sawdust media cultivation of Lentinula edodes fruiting bodies, collected in China (JMI10050)The highest essential amino acid content, assessed by log cultivation of Lentinula edodes fruiting bodies, collected in Jangheung (JMI10059). Sixteen free amino acids were detected in Lentinula edodes fruiting bodies, and the major free amino acids were histidine, glutamic acid, and arginine. The highest essential amino acid including threonine, valine, methionine, isoleucine, leucine, phenylalanine, histidine, and lysine was fromsawdust media cultivation of Lentinula edodes fruiting bodies collected in China(JMI10052). The ${\beta}$-glucan content from log cultivation of Lentinula edodes fruiting bodies collected in Korea (JMI10059 and JMI10066) was higher than that from sawdust media cultivation of Lentinula edodes fruiting bodies collected in China. The highest ${\beta}$-glucan content was observed from log cultivation of Lentinula edodes fruiting bodies collected in Korea (JMI10066).

As the amount of rice straw collected increases, green manure crops are used to provide the needed organic matter. However, as green manure crops generate methane in the process of decomposition, we tested with different tillage depths in order to reduce the emission. The atmosphere temperature of the chamber was $25{\sim}40^{\circ}C$ during the examination of methane and soil temperature was $2{\sim}10^{\circ}C$ lower than air temperature. The redox potential (Eh) of the soil drastically fell right before irrigated transplanting and showed -300~-400 mV during the cultivating period of rice (7~106 days after transplant). When hairy vetch was incorporated to soil and the field was not irrigated, the generation of methane did not occur from 12 to 4 days before transplanting rice and started after irrigation. Regarding the pattern of methane generation during the cultivation of rice, methane was generated 7 days after transplanting, reached the pinnacle at by 63~74 days after transplanting, rapidly decreased after 86~94 days past transplanting and stopped after 106 days past transplanting. When tested by different soil types, methane emission gradually increased in loam and clay loam during early transplant, whereas it sharply increased in sandy loam. The total amount of methane emitted was highest in sandy loam, followed by loam and clay loam. In all three soil types, methane emission significantly reduced when tillage depth was 20 cm compared to 10 cm. The rice growths and yield were not affected by tillage depth. Therefore, reduction of methane emission could be achieved when application hairy vetch to the soil with tillage depth of 20 cm in paddy soil.
Optical and microwave remote sensing data have been widely used in land cover and land use classification. Thanks to the spectral absorption characteristics of ground object in visible and near infrared region, optical data enables to extract different land cover types according to their material composition like water body, vegetation cover or bare land. On the other hand, microwave sensor receives backscatter radiance which contains information on surface roughness, object density and their 3-D structure that are very important complementary information to interpret land use and land cover. Separate use of these data have brought many successful results in practice. However, the accuracy of the land use / land cover established by this methodology still has some problems. One of the way to improve accuracy of the land use / land cover classification is just combination of both optical and microwave data in analysis. In this paper for the research, the author used LANDSAT TM scene 127/45 acquired on October 21, 1992, JERS-1 SAR scene 119/265 acquired on October 27, 1992 and aerial photographs taken on October 21, 1992. The study area has been selected in Hanoi City and surrounding area, Vietnam. This is a flat agricultural area with various land use types as water rice, secondary crops like maize, cassava, vegetables cultivation as cucumber, tomato etc. mixed with human settlement and some manufacture facilities as brick and ceramic factories. The use of only optical or microwave data could result in misclassification among some land use features as settlement and vegetables cultivation using frame stages. By combination of multitemporal JERS-1 SAR and TM data these errors have been eliminated so that accuracy of the final land use / land cover map has been improved. The paper describes a methodology for data combination and presents results achieved by the proposed approach.

The application of traditional taro propagation methods for large-scale cultivation would be insufficient to meet the high demand for quality planting materials. Therefore, this study aimed to develop an in vitro micro-propagation technique for two local taro cultivars (cv.), Wangi and Putih. Taro cormels were collected from the Malaysian Agricultural Research and Development Institute (MARDI) germplasm (Serdang, Malaysia). Explants were taken from the shoot tip of cormels and initially cultured on Murashige and Skoog (MS) basal media for four weeks. The explants were then transferred to different multiplication media supplemented with different types and concentrations of cytokinins such as 6-benzylaminopurine (BAP ) and Thidiazuron (TDZ). Shoot production was quantified after six weeks of culture. The highest mean number of new shoots was produced by the Wangi cultivar on MS medium supplemented with 2.0 mg/l BAP (2.10 shoots), MS medium supplemented with 0.5 mg/l TDZ (2.18 shoots), and Gamborg B5 medium supplemented with 6.0 mg/l BAP (2.43 shoots). The maximum average number of the Putih cultivar shoots was obtained on MS supplemented with 2.0 mg/l BAP (3.57 shoots). MS basal media was used for root initiation, as it produced an average of 25 roots with an 11-cm length. Various types of substrate mixtures were used during acclimatization. The best acclimatization substrate for the Wangi cultivar was 100% peat soil, whereas the Putih cultivar grew optimally in a combination of peat and perlites at a 1:1 ratio. Taro plantlets require approximately 4 to 6 weeks to acclimatize before they can be transferred to the field.
