  • Lithofacies Palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China
    Journal of Palaeogeography 2014, 3(4): 384-409 DOI: 10.3724/SP.J.1261.2014.00063 Lithofacies palaeogeography and sedimentology Lithofacies palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China Jin-Xiong Luo*, You-Bin He, Rui Wang School of Geosciences, Yangtze University, Wuhan 430100, China Abstract The lithofacies palaeogeography of the Late Permian Wujiaping Age in Middle and Upper Yangtze Region was studied based on petrography and the “single factor analysis and multifactor comprehensive mapping” method. The Upper Permian Wujiaping Stage in the Middle and Upper Yangtze Region is mainly composed of carbonate rocks and clastic rocks, with lesser amounts of siliceous rocks, pyroclastic rocks, volcanic rocks and coal. The rocks can be divided into three types, including clastic rock, clastic rock-limestone and lime- stone-siliceous rock, and four fundamental ecological types and four fossil assemblages are recognized in the Wujiaping Stage. Based on a petrological and palaeoecological study, six single factors were selected, namely, thickness (m), content (%) of marine rocks, content (%) of shallow water carbonate rocks, content (%) of biograins with limemud, content (%) of thin- bedded siliceous rocks and content (%) of deep water sedimentary rocks. Six single factors maps of the Wujiaping Stage and one lithofacies palaeogeography map of the Wujiaping Age were composed. Palaeogeographic units from west to east include an eroded area, an alluvial plain, a clastic rock platform, a carbonate rock platform where biocrowds developed, a slope and a basin. In addition, a clastic rock platform exists in the southeast of the study area. Hydro- carbon source rock and reservoir conditions were preliminarily analyzed based on lithofacies palaeogeography.

  • Combining Ability for Seed Yield and Other Characters in Rapeseed
    CORE Metadata, citation and similar papers at core.ac.uk Provided by Suranaree University of Technology Intellectual Repository COMBINING ABILITY FOR SEED YIELD AND OTHER CHARACTERS IN RAPESEED Zesu Huang1,3, Paisan Laosuwan2,*, Thitiporn Machikowa3 and Zehui Chen1 Received: Aug 7, 2009; Revised: Nov 2, 2009; Accepted: Nov 24, 2009 Abstract Rapeseed (Brassica napus L.) is one of the most important oilseed crops of China. The improvement of yield and oil content is presently being emphasized for this crop. The objective of this study was to evaluate combining ability of rapeseed lines to be used in breeding for yield, oil content and other characters. Nine inbred lines used as males were crossed to five recessive genetic male sterile (RGMS) lines used as females in a factorial manner (NCII design) to produce 45 single crosses. The crosses and their parents were tested at Guiyang and Zunyi, Guizhou, China in 2007-2008. The results showed that mean squares for hybrids were significantly different for all characters. The SS ratios of sum of squares due to GCA to sum of squares of hybrids were 0.70, 0.80, 0.88 and 0.82 for seed yield, oil content, days to flowering and days to maturity, respectively, but SCA effects were significant for all characters except for days to maturity. This indicates that both additive and non-additive gene effects were important, but additive gene effects were more predominant for these characters. Males III188, III224, and Q034 gave large positive GCA effects for seed yield. Their respective values were 317.6, 253.1, and 383.5 kg ha-1.

  • BEDRI KARAKAS the Role of Sorbitol Synthesis in Photosynthesis of Peach (Prunus Persica) (Under the Direction of MARK W
    BEDRI KARAKAS The role of sorbitol synthesis in photosynthesis of peach (Prunus persica) (Under the Direction of MARK W. RIEGER) This dissertation examines the hypothesis that polyol synthesis enhances photosynthetic capacity in peach and related species. Members of Prunus synthesize, translocate, and utilize sorbitol as their main photosynthetic end product whereas most other plants utilize sucrose for those purposes. First, I approached this hypothesis by examining eight genetically diverse Prunus species with various sorbitol: sucrose ratios and activities of sorbitol-6-phosphate dehydrogenase (S6PDH), principal sorbitol synthesis enzyme. Leaf photosynthetic capabilities (A), in vitro activity of the S6PDH and sorbitol contents of greenhouse grown plants were measured. I found an inverse relation between A and S6PDH activity of the species. This observation does not support the working hypothesis and that sorbitol synthesis enhances A. Second, I used two peach varieties (i.e., Encore and Nemaguard) to examine the same hypothesis within a single species by source/sink manipulations (i.e., fruiting versus non-fruiting, fruit present versus fruit removed, and shoot tip removal) and existing natural variation (i.e., leaf node position). In all cases, except fruiting versus non-fruiting and fruit present, photosynthesis and S6PDH enzyme activity showed positive correlations. Finally, I analyzed the response of S6PDH gene to shoot tip removal treatment in connection with S6PDH activity and A in potted Nemaguard peach plants. To document hourly changes, leaves were sampled three times during the day (i.e., sunrise, midday, and sunset) and analyzed for S6PDH gene expression and S6PDH activity. Sorbitol-6-phosphate dehydrogenase mRNA transcript levels significantly increased while S6PDH activity decreased 24-hour following shoot tip removal.

In this paper, we report a new case of Bauxite deposit uranium enrichment in a paleo-karstic bauxite deposit at Yunfeng, southwestern China, present electron probe Uranium minerals micro-analyzer (EPMA) and Raman spectroscopic evidence for the presence of separate U-minerals, and propose EPMA a model in which uranium was enriched through successive processes from chemical weathering through early Raman spectroscopy to burial diagenesis. The Yunfeng bauxite ores, developed in Lower Carboniferous mudrocks overlying Middle to Yunfeng Guizhou Upper Cambrian carbonate rocks, contain 18.0 to 62.4 ppm (average 35.1 ppm) U, which is much high than the abundances in average crustal rocks (1–3 ppm). Micron-sized uraninite occurs as rims of Ti-oxides, fillings of micro-fractures in kaolinite, and disseminated grains in association with sulfides in the matrix of diaspore and kaolinite.

  • Mercury Accumulation in Vegetable Houttuynia Cordata Thunb. from Two
    www.nature.com/scientificreports OPEN Mercury accumulation in vegetable Houttuynia cordata Thunb. from two diferent geological areas in southwest China and implications for human consumption Qingfeng Wang1,2*, Zhonggen Li1,2, Xinbin Feng2, Ao Wang4, Xinyu Li2,3, Dan Wang1 & Leilei Fan1 Houttuynia cordata Thunb. (HCT) is a common vegetable native to southwest China, and grown for consumption. The results suggested that THg contents in all parts and MeHg in underground parts of HCT in Hg mining areas were much higher than those in non-Hg mining areas. The highest THg and MeHg content of HCT were found in the roots, followed by the other tissues in the sequence: roots > leaves > rhizomes > aboveground stems (THg), and roots > rhizomes > aboveground stems > leaves (MeHg). The average THg bioaccumulation factor (BCF) of HCT root in the Hg mining area and in non-Hg mining areas could reach 1.02 ± 0.71 and 0.99 ± 0.71 respectively, indicating that HCT is a Hg accumulator. And the THg and MeHg contents in all tissues of HCT, including the leaves, were signifcantly correlated with THg and MeHg content in the soil. Additionally, preferred dietary habits of HCT consumption could directly afect the Hg exposure risk. Consuming the aboveground parts (CAP) of HCT potentially poses a high THg exposure risk and consuming the underground parts (CUP) may lead to a relatively high MeHg exposure risk. Only consuming the rhizomes (OCR) of the underground parts could signifcantly reduce the exposure risk of THg and to some extent of MeHg. In summary, HCT should not be cultivated near the Hg contaminated sites, such as Hg tailings, as it is associated with a greater risk of Hg exposure and high root Hg levels, and the roots should be removed before consumption to reduce the Hg risk.

    China China-7: Bailongjiang China-8: Youjiang China-9: Huang-he Bailongjiang 27 Introduction China, in the southeast of Eurasia, faces the Pacific Ocean on the southeast, stretches northwestward to the interior of Asia and borders the South Asian sub-continent on the southwest. As the world's third largest country in area, China has a vast territory which spans for about 620 longitude from east to west and 500 latitude from north to south, and covers an area of 9 600 000 km2. The topographical conditions of China are very complex, but the general tendency is higher in the west and lower in the east. The climatic conditions of China are complex and multiple in nature. Monsoon climate is a predominant feature of the country which, with its most part under the influence of SE and SW monsoons possesses the peculiarity that it is humid and ample in rainfall around the southeast while dry and scarce in precipitation in the northwest. Generally, the regional distribution of precipitation in China is extensively uneven. According to the quantity and character of precipitation in various areas, the country can be divided into 5 types of zones, viz. a very humid zone, a humid zone, a semi-humid zone, a semi-arid zone and an arid zone. The mean annual precipitation is 608 mm varying from 1 600 mm the southeast and southwest to less than 200 mm in the north and northwest. China is a country having a large number of rivers. There are about 5 000 rivers each with a catchment area in excess of 1 000 km2.
