A New Biflavone and Further Flavonoids from the Moss Hylocomium splendens
Whereas many reports now exist on flavonoids of liverworts only few publications are concerned with the flavonoid pattern of mosses [1—5]. The detection of an apigenin 7-O-rhamnoglucoside from H yloco mium splendens was reported [6]. Screening chroma tograms of samples of H. splendens collected at about 20 different localities showed however a much richer flavonoid pattern as supposed previou...
متن کاملRole of Selenite and Selenate Uptake by Maize Plants in Chlorophyll A and B Content
Abstract—Extracting and determining chlorophyll pigments (chlorophyll a and b) in green leaves are the procedures based on the solvent extraction of pigments in samples using N,Ndimethylformamide as the extractant. In this study, two species of soluble inorganic selenium forms, selenite (Se) and selenate (Se) at different concentrations were investigated on maize plants that were growing in nut...
متن کاملCritical remarks on the use of terrestrial moss (Hylocomium splendens and Pleurozium schreberi) for monitoring of airborne pollution.
Duplicate samples of the two terrestrial moss species Hylocomium splendens and Pleurozium schreberi, which are widely used to monitor airborne heavy metal pollution, have been collected from eight catchments spread over a 1,500,000 km2 area in northern Europe. These were analysed for a total of 38 elements by inductively coupled plasma-mass spectrometry, inductively coupled plasma-atomic emissi...
متن کاملEffect of Selenite and Selenate Uptake by Maize Plants on Specific Leaf Area
Abstract—Specific leaf area (SLA; cmleaf gleaf) the ratio of leaf area to leaf dry mass is a key ecophysiological parameter influencing leaf physiology, photosynthesis, and whole plant carbon gain and also can be used as a rapid and diagnostic tool. In this study, two species of soluble inorganic selenium forms, selenite (Se) and selenate (Se) at different concentrations were investigated on ma...
متن کاملTestate amoebae (Protista) communities in Hylocomium splendens (Hedw.) B.S.G. (Bryophyta): relationships with altitude, and moss elemental chemistry.
We studied the testate amoebae in the moss Hylocomium splendens along an altitudinal gradient from 1000 to 2200 m asl. in the south-eastern Alps of Italy in relation to micro- and macro-nutrient content of moss plants. Three mountainous areas were chosen, two of them characterised by calcareous bedrock, the third by siliceous bedrock. A total of 25 testate amoebae taxa were recorded, with a mea...
