2012-04-17Rediscovered Phylogenetics of Wenchengia (Lamiaceae)Chow was established on the basis of two collections(four sheets)from the 1930s.The genus is characterized by alternate leaves,racemose inflorescences,and a unique type of nutlet attachment described as vascular funicles and slender stalks,and was assigned to a monotypic subfamily,Wenchengioideae,based on its morphological uniqueness in Lamiacea... Wenchengia C. Y. Wu & S. Chow, a rare and endangered monotypic genus of Lamiaceae, is endemic to the island of Hainan. The genus and its sole member species, W. alternifolia C. Y. Wu & S. Chow was established on the basis of two collections (four sheets) from the 1930s. The genus is characterized by alternate leaves, racemose inflorescences, and...Read More -
2012-02-24The study progress of coevolution of fig and fig wasp in South China Botanical Garden,Moraceae).They are shaped like a hollow ball,lined on their inner surface by numerous tiny female flowers. Pollination is carried out by host-specific fig wasps(Agaonidae).Female pollinators enter the figs through a narrow entrance gate. Most NPFW oviposit from the outside of figs,making peripherally-located pollinator larvae more prone to atta... Figs are the inflorescences of fig trees (Ficus spp. Moraceae). They are shaped like a hollow ball, lined on their inner surface by numerous tiny female flowers. Pollination is carried out by host-specific fig wasps (Agaonidae). Female pollinators enter the figs through a narrow entrance gate. They lay their eggs into the ovules, via the stigmas...Read More -
2012-01-13Effects of Plant Functional Group Removal on Microbial Substrate Metabolic Function and Soil Respiration in Subtropical Eucalyptus PlantationsSince aboveground communities and belowground communities are intimately linked and these linkages greatly affect ecosystem properties,removal of plant functional groups from aboveground communities will exert a great impact on belowground communities. Based on the previous works that found plant functional group removal greatly altered soil mic... Since aboveground communities and belowground communities are intimately linked and these linkages greatly affect ecosystem properties, removal of plant functional groups from aboveground communities will exert a great impact on belowground communities.

2011-11-08More Factors should be Considered in Prediction of Forestry Productivity Based on BiomassThe relationship between tree productivity and biomass not only re□□ects plant adaptation and the interaction of plants and the environment,but also has signi□□cant implications in global carbon cycling,climate change,and forest management. Age)and then both linear regression model and allometric equation(i. Power function)were applied to de... The relationship between tree productivity and biomass not only re？ects plant adaptation and the interaction of plants and the environment, but also has signi？cant implications in global carbon cycling, climate change, and forest management. However, how biotic factors (e.g. tree age, diameter at breast height [DBH], height) and abiotic factor...Read More

2011-10-25Professor BAI Chunli Inspects South China Botanical GardenBai paid a keen attention to the laboratories with the aims of three“key breakthrough strategies”and five key research directions. He also introduced to Prof. He pointed out that SCBG not only should obtain the original achievements in the research fields of basic botany and theoretical ecology,but also produce a marked effect in national stra... On October 20, Prof. BAI Chunli, the President of Chinese Academy of Sciences (CAS), made an inspection of South China Botanical Garden (SCBG), accompanied by Prof. ZHAN Wenlong, the Vice President of CAS. Prof. HUANG Hongwen, director of SCBG, and Profs. REN Hai and FU Shenglei, deputy directors of SCBG, and some principal investigators warmly ...Read More

2011-10-21Allotetraploid Origin and Divergence in EleusineHybridization followed by allopolyploidization is a principal speciation mode for Eleusine(Poaceae)in East Africa and Americas. LIU Qing of South China Botanical Garden and her cooperators of Smithsonian Institution employ two LCN markers and plastid markers to support independent allotetraploid origins for E. 200922).The paper has been publishe... Hybridization followed by allopolyploidization is a principal speciation mode for Eleusine (Poaceae) in East Africa and Americas. Recently, Dr. LIU Qing of South China Botanical Garden and her cooperators of Smithsonian Institution employed two LCN markers and plastid markers to support independent allotetraploid origins for E. kigeziensis and t...Read More

2011-10-18Increased Phosphorus Availability Mitigates the Inhibition of Nitrogen Deposition on CH4 Uptake in an Old-growth Tropical ForestMore and more studies indicate that,nitrogen deposition inhibites forest soil methane(CH4)uptake. MO Jiangming from ecosystem management group of South China Botanical Garden(SCBG).Recently,Dr. This work was guided by Prof. MO Jiangming from ecosystem management group of SCBG and Prof. This finding firstly revealed the effects of N/P interaction... More and more studies indicate that, nitrogen deposition inhibites forest soil methane (CH4) uptake. Consequently, nitrogen (N) deposition increases atmospheric CH4 concentration due to weaken the function of forest soil as CH4 sink. This standpoint has been supported by Dr. ZHANG Wei (Zhang et al., Journal of Geophysical Research-Atmospheres, 2...Read More
