Sedum peltatum M.L. Chen et X.H. Cao, belonging to the family Crassulaceae DC., is described and illustrated from China as a new species. It was collected from Nanwu canyon, Huangnikeng valley, Gaokeng valley and Qingshikeng valley in the Jiulong Mountains, China (P. R.). Morphological diagnostic characters of closely related species are also discussed. Introduction Sedum L. is the largest and ...

(14)CO(2) photoassimilation in the presence of MgATP, MgADP, and MgAMP was investigated using intact chloroplasts from Sedum praealtum, a Crassulacean acid metabolism plant, and two C(3) plants: spinach and peas. Inasmuch as free ATP, ADP, AMP, and uncomplexed Mg(2+) were present in the assays, their influence upon CO(2) assimilation was also examined. Free Mg(2+) was inhibitory with all chloro...

Urbanization leads to higher phosphorus (P) concentration in urban catchments. Among different stormwater retention measures, green roofs are the least efficient in phosphorus retention. Moreover, much research has shown that green roofs act as sources of phosphorus, and they can emit P in significant loads. In this study low P emission green roof substrate was developed based on the proposed s...

The ethnopharmacology of Madeira and Porto Santo Islands is extremely interesting because of the cultural and biogeographic features of this region, which make it a centre of medicinal plant diversity (richness of endemic flora, geographical isolation in the Atlantic sea, crosscultural influences, and past abundance of local healers). The medicinal flora of Madeira is composed of 259 species. S...

The green roof technology provides environmental benefits by protecting the base roof membrane of buildings against solar radiation and temperature fluctuations and by helping to reduce building’s energy consumption by direct shading. Although several investigations have been performed to explore the energy performance of vegetated roofs as natural cooling devices, there is a lack of data conce...

The present study demonstrates the development of an Agrobacterium-mediated genetic transformation method for species of the Sedum genus, which includes the Cd/Zn hyperaccumulator Sedum plumbizincicola and the non-hyperaccumulating ecotype of S. alfredii. Multiple shoots were induced from stem nodes of two Sedum plants using Murashige and Skoog (MS) medium containing 0.1 mg/L cytokinin 6-benzyl...

Sedum sarmentosum is an important Chinese medicinal herb that exhibits anti-inflammatory, anti-angiogenic and anti-nociceptive properties. However, little is known about its genetic background. The first set of 14 microsatellite markers were isolated and characterized for S. sarmentosum using an SSR-enriched library. Fourteen polymorphic microsatellite markers were acquired with satisfactory am...

Green roofs have the potential to function as islands of biodiversity within urban and suburban environments. However, plant diversity is constrained by the harsh environment of a green roof, especially summertime water deficit and heat stress. We hypothesized that Sedum species, which are highly tolerant of the roof-top environment, would reduce peak soil temperature and increase performance o...

Background and aims The application of green roof technology has become more common in the central, northwestern and eastern USA, and is now being employed across the southern USA as well. However, there is little research in the literature that evaluated plant survival on unirrigated green roofs in subtropical climates that experience frequent drought and heat stress. Here, we summarize the re...

Extensive green roof is one of the sustainable urban stormwater management alternatives to manage and mitigate surface runoff. In order implement roofs more effectively, suitable plant species substrate components for tropical climate must be identified. The aim this study investigate evapotranspiration (ET) behaviors in extensive based on different types local native species. Four test beds co...
