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 -
