We studied the effects of applying 50 kg(N) ha-1 year-1 nitrogen (N) on needle photosynthesis, N allocation and nutrient content in sun- shade crowns hybrid larch F1 (Larix gmelinii var. japonica × L. kaempferi). The light-saturated net photosynthetic rate (P Nmax) was not significantly affected by application or crown position, although contents N, P, K, chlorophyll (Chl), maximum rates carboxylation electron transport were lower needles than sun crown. This difference mainly due to an...
Recent estimates show that land degradation is rapidly progressing worldwide. Therefore, efforts are being made in Korea toward Land Degradation Neutrality (LDN) to extend the development of green areas. As part this effort, artificial ecosystems created through land-use changes restored forests. We examined grassland change, an afforested site planted for forest restoration, and a nearby primary according LDN indicators. The about 40 years ago showed higher bulk density available phosphorus...
Soil acidification caused by anthropogenic activities adversely affects forest ecosystems altering soil pH, which is an important factor in quality and function. Liming one suggested way to solve this problem. This study was performed evaluate the effects of liming acidic soils determining microbial biomass, community structure, extracellular enzyme associated with carbon, nitrogen, phosphorus cycling. Lime treatment increased pH up 40%, significantly organic matter (OM) content at some...
Drought damage and waterlogging are the most frequent abiotic injuries throughout lifespan of trees. Nonetheless, because signs visible similar between these types injury, physiological indicators must be analyzed to make a scientific differential diagnosis. This study was aimed at investigating growth drought (DS) stress (WL) in Prunus yedoensis. Overall indices such as tree height, diameter root collar (DRC), total dry weight could ranked decreasing order "control > DS WL." In particular,...
Trichomoniasis is the most common curable sexually-transmitted infection (STI) worldwide. There are few reports on prevalence of Trichomonas vaginalis in Korea. The purpose this study was to examine trichomoniasis by PCR Guri city, All adult women who visited Hanyang University Hospital for health screening within National Health Care Service were invited participate study, and 424 enrolled between March June 2011. used detect using primers based a repetitive sequence cloned from T....
The analytical method of silicon dioxide (SiO2) in health functional food products was developed employing inductively coupled plasma optical emission spectrometry (ICP-OES) assisted by acid (hydrofluoric and boric acid) digestion open system without alkali fusion. limit detection (LOD) quantification (LOQ) this were found to be 0.07 0.20 mg/L, respectively. Linearity (r 2) linear range 0.99 0.20~20.0 accuracy precision SiO2 (0.4, 1.0, 2.0%, w/w) spiked glucosamine exhibited the 90.22~94.14%...
This study presents the possible application of airborne Light Detection And Ranging (LiDAR) survey technique to extract a cadastral shoreline in South Korea for first time. paper summarizes results two case studies compare LiDAR-derived with other data sources, such as digital topographic map, seamless and surveying. In this current study, well-known contouring method is used shorelines combination Digital Elevation Models (DEMs) aerial images. Approximate Highest High Water Level (AHHWL)...
We investigated the relationship between vegetation type and soil carbon dynamics in even-aged alder (Alnus hirsuta) Korean pine (Pinus koraiensis) plantations central Korea. Both forests were located on same parent material occupied similar topographic positions. Soil <TEX>$CO_2$</TEX> efflux two was determined using a dynamic chamber method accompanied by measurements of moisture content temperature. Mean temperature plantations, but mean water significantly higher plantation than...
Using a fumigation sterilizer (Dazomet) for nematode control, this study determined the effect of soil sterilization on quantity and quality growth Pinus densiflora Siebold & Zucc. Larix kaempferi (Lamb.) Carrière seedlings in an open-field nursery at Jeongseon-gun, Kangwon-do, Republic Korea. Most nematodes disappeared after fumigant sterilization. The organic matter content, cation exchange capacity, Mg2+ content increased significantly, but electrical conductivity (EC) decreased. pine...
