Oxygen microgradients in the rhizosphere of the mangrove Avicennia marina
Oxygen concentration was measured in aerial roots (pneumatophores), horizontal cable roots and surrounding sediment of the tree Avicennia marina (Forsk.) Vierh. in a mangrove swamp at Ao Nam Bor, on the southeast coast of Phuket Island, Thailand. The O2 measurements were made in the field with a polarographlc oxygen minielectrode. The O2 concentration inside pneurnatophores was 63 to 88 % of ai...
متن کاملPhotosynthetic and Stomatal Responses of the Grey Mangrove, Avicennia marina, to Transient Salinity Conditions.
Measurements of gas exchange characteristics were made on intact, attached leaves of hydroponically grown seedlings of Avicennia marina (Forstk.) Vierh. var australasica (Walp.) Moldenke as the NaCl concentration of the culture solution was varied by step changes of 50 millimolar NaCl every 2nd day from 50 to 500 to 50 millimolar NaCl. The CO(2) assimilation rate, stomatal conductance, intercel...
متن کاملPlant Growth Promoting of Endophytic Sporosarcina aquimarina SjAM16103 Isolated from the Pneumatophores of Avicennia marina L.
Endophytic Sporosarcina aquimarina SjAM16103 was isolated from the inner tissues of pneumatophores of mangrove plant Avicennia marina along with Bacillus sp. and Enterobacter sp. Endophytic S. aquimarina SjAM16103 was Gram variable, and motile bacterium measured 0.6-0.9 μm wide by 1.7-2.0 μm long and light orange-brown coloured in 3-day cultures on tryptone broth at 26°C. Nucleotide sequence of...
متن کاملIridoids from Avicennia marina.
Three new iridoid glucosides, 10-O-[(E)-cinnamoyl]-geniposidic acid, 10-O-[(E)-p-coumaroyl]-geniposidic acid, 10-O-[(E)-caffeoyl]-geniposidic acid and the known iridoid glucoside, 2'-O-[(E)-cinnamoyl]-mussaenosidic acid have been isolated from Avicennia marina. The structures were determined primarily by NMR spectroscopy. The assignment of NMR signals was performed by means of 1H-1H COSY, HMQC ...
متن کاملDiurnal Pattern of Salt Secretion in Leaves of the Black Mangrove , Avicennia marina
Avicennia marina (Forsk.) Vierh has a typical diurnal pattern of salt gland activity, with high secretion rate during the day, a peak at noon, declining after sunset, and remaining low throughout the night. The main factor affecting the daily secretion rhythm was radiation, with a 2-hr time lag between the radiation level and the corresponding secretion. This lag might be a result of a salt acc...
