| 1 | Phytolith carbon sequestration in bamboos of different ecotypes:a case study in China显示文摘Occlusion of carbon(C) within phytoliths(Phyt OC) is becoming one of the most promising terrestrial C sequestration mechanisms. This study explored the production of Phyt OC within 35 bamboo species belonging to three ecotypes using methods of microwave digestion. The aim of this study is to explore the present and potential C sequestration rate within phytoliths of bamboo species from three ecotypes. Phyt OC content in bamboos of three ecotypes ranges from 0.07 % to 0.42 %. The mean Phyt OC production flux decreases as: clustered bamboo(0.050 ±0.016 t CO2ha-1a-1) & mixed bamboo(0.049 ± 0.016 t CO2ha-1a-1) [ scattered bamboo(0.038 ± 0.020 t CO2ha-1a-1). The phytolith carbon sequestration in Chinese bamboo is estimated to be 0.293 ± 0.127 Tg(1 Tg =1012g) CO2a-1; approximately 75 %, 3 %, and 22 % of which is contributed from scattered, mixed and clustered bamboo, respectively. Taking the Phyt OC production flux of 0.18 ± 0.12 t CO2ha-1a-1and current annual area increasing rate of 3 %, global bamboo phytoliths wouldsequester 11.9 ± 7.9 Tg CO2a-1by 2050. Consequently,bamboo forests have significant potential to mitigate the increasing concentration of atmospheric CO2 by maximizing Phyt OC production flux and expanding bamboos. | Beilei Li Zhaoliang Song Hailong Wang Fengshan Guo Renyi Gui Xiaomin Yang Ruisheng Song | 2014 | Chinese Science Bulletin2014，59，34： | 2 |

| 3 | Human Disturbance Reduces Plant Species Diversity and Stability of Phyllostachys pubescens Forests显示文摘Plant species diversity is an important index reflecting the functional complexity and stability of ecosystems.Human activity can completely alter plant species diversity and cause serious degradation of ecosystems but its impact on bamboo forest still lacks of systematic evaluation.In this study,we performed a field investigation to reveal the influences of human disturbances on the plant diversity and stability of Moso bamboo forests at Southern China.The selected bamboo fields contained different intensities of human activities that could be classified as slight,moderate and severe disturbance level.Species richness index S,Shannon-Wienner index H,Simpson index D,Pielou index Jsw,community similarity index IS and community stability index were employed to quantitatively evaluate the plant species diversity and stability.The survey revealed that there were 203 species belonging to 83 families and 108 genera in Moso bamboo forests.The number of plant species in the Moso bamboo forests decreased with the increasing of disturbance intensity.The species diversity indexes generally followed the order of slight>moderate>severe disturbance,as well as the richness index S,Shannon-Wienner index H and Pielou index Jsw.The similarity and species stability of the bamboo forest communities also decreased with the increase of the disturbance intensity.Under the severe disturbance,plant species replacement occurred strongly.The obtained results provide some a guideline for the sustainable management of bamboo forest. | Ji Lei Rong Chen Renyi Gui Jianshuang Gao | 2020 | Research in Ecology2020，2，1： | 1 |

| 5 | Nitrogen Release Characteristics of a Bag Controlled Release Fertilizer显示文摘Slow release fertilizers are designed to enhance crop yield and minimizing the loss of nitrogen(N)to environment.However,N release in leaching and loss in ammonia emission from bag controlled release fertilizers have not been previously evaluated under the standardized conditions in soil.Accordingly,a laboratory study was conducted to evaluate the characteristics of N release from a bag controlled fertilizer with 1,3,5 and 7 rows of hole(B-1,B-3,B-5,B-7)and a kraft bag without hole(B-W).The results showed that the amount of N leaching of B-1,B-3,B-5,B-7 and B-W were significantly lower than urea fertilizer without bag(U).The maximum N release from the fertilizers followed the order:U(83.16%)>B-7(54.61%)>B-5(54.02%)>B-W(51.51%)>B-3(48.87%)>B-1(38.60%)during the experimentation.Compared with U treatment,ammonia volatilization losses were significantly decreased by B-1,B-3,B-5,B-7 and B-W treatments.Based on N release and loss,a suitable bag with holes should be considered in practice when using the bag controlled fertilizer to meet an environment good objective.The evaluation method merits further study combined with field experiment. | Yi Zhong Renyi Gui Zhuangzhuang Qian Shunyao Zhuang | 2020 | Research in Ecology2020，2，1： | 0 |
| 6 | Research Progress on Speciation of Selenium Compounds in Plants显示文摘Selenium(Se) is an essential trace element, which humans and animals take directly or indirectly from plants.This paper reviewed the recent research progress on speciation of selenium compounds in plants,including the kinds of selenium compounds and their metabolic pathways,and the technology for sample treatment,separation,and determination. Organic selenium compounds are the major parts of the selenium speciation in plants.The technology of ultrasonic-microwave synergistic extraction combined with enzymatic hydrolysis is useful in sample preparation.HPLC-ICP-MS is widely used in determining selenium speciation.It is important to develop more standard selenium compounds and pay more attention to selenoprotein in plants.ESMS,ESMS -MS and MALDI-TOF can be applied to identifying the unknown selenium compounds.The application of IDA in determining both the metabolic pathways and the structure of large selenium molecules will be a major aspect for the future research. | Cheng Jianzhong Yang Ping Gui Renyi | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
| 7 | Case study of a rhizosphere microbiome assay on a bamboo rhizome with excessive shoots显示文摘Young moso bamboo shoots are a popular seasonal food and an important source of income for farmers,with value for cultivation estimated at$30,000 per hectare.Bamboo also has great environmental importance and its unique physiology is of scientific interest.A rare and valuable phenomenon has recently appeared where a large number of adjacent buds within a single moso bamboo rhizome have grown into shoots.Although of practical importance for the production of edible shoots,such occurrences have not been scientifically studied,due to their rarity.Analysis of collected reports from enhanced shoot production events in China showed no evidence that enhanced shoot development was heritable.We report the analysis of the rhizosphere microbiome from a rhizome with 18 shoots,compared to rhizomes having one or no shoots as controls.The community of prokaryotes,but not fungi,correlated with the shoot number.Burkholderia was the most abundant genus,which was negatively correlated with rhizome shoot number,while Clostridia and Ktedonobacteria were positively correlated.Two Burkholderia strains were isolated and their plant-growth promoting activity was tested.The isolated Burkholderia strains attenuated the growth of bamboo seedlings.These data provide the first study on excessive shoot development in bamboo,which will facilitate hypothesis building for future studies. | Fuqiang Cui Yifan Yang Mengyuan Ye Wei Wei Wenqian Huang Ying Wu Xi Jiao Xiaoxue Ye Shutong Zhou Zhubing Hu Yinhai Zhang Renyi Gui Wenwu Wu Kim Yrjala Kirk Overmyer Shenkui Liu | 2021 | Forestry Research2021，1，1： | 0 |
