2011-06-20The Uncertainty Determination of Emergy Analysis ModifiedThe conflict between environmental protection and further economic development is becoming a much serious problem in front of human being nowadays. Furthermore,they may be also useful in quantifying the uncertainty in ecosystem models and scaling up or down in ecological studies The results of this study will contribute greatly to the uncertaint... The conflict between environmental protection and further economic development is becoming a much serious problem in front of human being nowadays. To realize human being’s sustainable development, some scientific methods are firstly required to objectively evaluate the real wealth，including both economic and environmental aspects.

2011-06-07Different Management Practices Have Important Influences to Emission of Soil Greenhouse Gases in Plantation EcosystemsCO2,CH4 and N2O are all important greenhouse gases,which mainly come from soil of forest ecosystems. At present,it is a highlight to research mechanisms of greenhouse gases from forest soil. To determine the effects ofunderstory removal and Cassia alata addition on emission of soil greenhouse gases,Dr. The fluxes of soil CO2 stay at a high level...

2011-06-03Subtropical Plantations are Large Carbon Sink: Evidence from Two Monoculture Plantations in South ChinaForest plantations occupy approximately 264 million ha worldwide,which support the increasing local and global demands for wood and have been considered as potential fast-response carbon sinks that may mitigate the rise of atmospheric CO2 concentrations. Moreover it is necessary to assess the effects of corrections for disturbances of soil tempe... Forest plantations occupy approximately 264 million ha worldwide, which support the increasing local and global demands for wood and have been considered as potential fast-response carbon sinks that may mitigate the rise of atmospheric CO2 concentrations. In China, the area of plantations is nearly 62 million ha because of large-scale reforestat...Read More

2011-05-26Tissue Culture on Energy Plant Euphorbia tirucalli Achieves SuccessThe genus Euphorbia includes succulent shrubs distributing in tropical and subtropical regions of the world. These plants increase their biomass promptly in semi-deserts. Terpenoids and sterols in plants are also industrially important chemical sources as vitamins,steroid compounds,insecticides,and anticancer drugs Application of information to ... The genus Euphorbia includes succulent shrubs distributing in tropical and subtropical regions of the world. These plants increase their biomass promptly in semi-deserts. Euphorbia plant cells accumulate sterols, di- and tri-terpenoids. The major components of Euphorbia latex are triterpenes; cracked or fermented latex can be used as fuel. Terpe...Read More -
2011-05-07South China Botanical Garden Finds Obligate Pollinators can Breakdown SporopolleninThe precise structure of sporopollenin is unknown. This chemical inertness accounts for the preservation of pollen grains for tens to hundreds of millions of years. No other insects visited the flowers of hot plants,and the moths’entire life cycle is adapted to their host plants’phenology and chemistry. The results showed that Phyllanthus coch... Sporopollenin is a complex polymer that is composed of fatty acids and phenolic compounds. The precise structure of sporopollenin is unknown. Sporopollenin is resistant to nonoxidative physical, chemical, and biological treatments and insoluble in both aqueous and organic solvents. This chemical inertness accounts for the preservation of pollen ...Read More -

2011-04-08South China Botanical Garden Finds a New Hyperaccumulator for Cd PhytoremediationPhytoremediation is a promising clean-up technology,which is to remedy soil heavy metal pollution with plants. Photeinocarpum showed no significant reduction with soil Cd treatment as high as 100 mg kg-1. In the transplanting-Cd concentration gradient experiment,plant shoot biomass was unaffected by soil Cd as high as 60 mg kg-1. Photeinocarpum ... Phytoremediation is a promising clean-up technology, which is to remedy soil heavy metal pollution with plants. The key to success of this technique is to find hyperaccumulators which can accumulate uniquely high quantities of heavy metals, for example, more than 1000 mg kg-1 for As, Pb, Cu, Ni, and Co, 10,000 mg kg-1 for Zn and Mn, and 100 mg k...Read More
