Leaf structure and water relations were studied in a temperate population of Avicennia marina subsp. australasica along a natural salinity gradient [28 to 49 parts per thousand (ppt)] and compared with two subspecies grown naturally in similar soil salinities to those of subsp. australasica but under different climates: subsp. eucalyptifolia (salinity 30 ppt, wet tropics) and subsp. marina (sal...

This paper attempts to integrate satellite imagery such as Cartosat-1 with high spatial resolution and IRS P6 LISS IV with high spectral resolution using digital image fusion algorithms. This integration and mixing of hispectral and higher spatial data with complementary spectral and spatial characteristics, has proved to be promising to obtain images with high spatial and spectral resolution s...

in vitro assessment of the antifungal activities was evaluated in the present study for both aqueous and ethanol extracts prepared from leaves of avicennia marina and rhizophora mucronata . leaves of mangrove species were collected from qeshm and syrik of south-east coast of iran, mangrove forest respectively. antimicrobial tests were carried out through disk diffusion method. minimum fungicida...

Measurement of intrathylakoid aqueous volumes by electron spin resonance spectroscopy was used to study ionic permeability properties of thylakoid membranes isolated from Beta vulgaris L. and Avicennia germinans L. The thylakoids behaved as perfect osmometers in the presence of sorbitol and betaine. Thylakoids exposed to hypertonic solutions of NaCl and KCl shrank and subsequently swelled, requ...

Two isolates of the diazotrophic filamentous cyanobacterium Microcoleus chthonoplastes, one obtained from black mangrove (Avicennia germinans) pneumatophores and one from cyanobacterial mats, were inoculated onto young mangrove seedlings to evaluate nitrogen transfer from the bacterium to the plants under in vitro conditions in closed system experiments. Total nitrogen and N incorporation in pl...
