Mangroves have wide applications in folk medicine since ages due to the presence of several bioactive compounds. This study aims to explore the antimicrobial activity of ten mangroves commonly found in Indian Sundarban region namely Avicennia alba, Avicennia marina, Avicennia officinalis, Excoecaria agallocha, Sonneratia caseolaris, Sonneratia apetela,Aegiceres corniculatum, Acanthus ilicifoliu...

Antioxidant activity of Avicenni marina L and Avicennia officinalis L fruit extracts in ethyl acetate, acetone, methanol and ethanol were studied by ABTS, CrO5 and FRAP method. All the extracts possessed significant amount of the antioxidant activity, extracts in methanol and ethanol was demonstrated convincingly higher antioxidant activity by all the three methods. Whereas, the ethyl acetate e...

BACKGROUND AND AIMS Successive vascular cambia are involved in the secondary growth of at least 200 woody species from >30 plant families. In the mangrove Avicennia these successive cambia are organized in patches, creating stems with non-concentric xylem tissue surrounded by internal phloem tissue. Little is known about radial growth and tree stem dynamics in trees with this type of anatomy. T...

The mangrove forests play a significant role as sediment traps. They reduce tidal flows and induce sedimentation of soil particles at low tide. However, there are no such processes taking place in the non-mangrove areas. Site of Avicennia-Rhizophora interphase is more efficient than Avicennia and or Rhizophora zones, in trapping the sediment by 30, 25 and 20% respectively at low tide as compare...

BACKGROUND Secondary growth by successive cambia is a rare phenomenon in woody plant species. Only few plant species, within different phylogenetic clades, have secondary growth by more than one vascular cambium. Often, these successive cambia are organised concentrically. In the mangrove genus Avicennia however, the successive cambia seem to have a more complex organisation. This study aimed (...

Avicennia marina (Tamil : Alai : Alai atti) : Avicennia marina is the dominant mangrose species in Karankadu and accounts for about 95% of the vegetative cover plant in Indian Sub-continent was investigated for endophytic mycoflora as a possible source of bioactive secondary metabolites. Being salinity resistant, this species dominate most mangrove area of the country including karankadu. Four ...

Pollen grains can play an important role in allergic diseases and many studies have revealed that allergenicity increases in industrial cities. In Bushehr province in Iran Avicennia marina (Forsk.) Vierh. has grown in two regions, Bordekhoon (Mond protected Area) and Assaluyeh (Marine National Park of Nayband). Assaluyeh (polluted area) is an industrial region with petrochemical factories that ...

A range of fungi occur in the mangrove ecosystem although these differ as to their location and some fungi occur more frequently than others. In a study dealing with the frequency of occurrence of manglicolous fungi on Avicennia and Bruguiera from a mangrove habitat of Kerala, South India, 32 manglicolous marine fungi belonging to 23 ascomycetes, 1 basidiomycete and 8 mitosporic fungi were obta...
