Mechanism of chlorophyll-a appearance and its locality in the intensive study area of the Ariake Sea, Japan in winter seasons is clarified by using remote sensing satellite data. Through experiments with Terra and AQUA MODIS data derived chlorophyll-a concentration and truth data of chlorophyll-a concentration together with meteorological data and tidal data which are acquired for 6 years (wint...

The MERIS Terrestrial Chlorophyll Index (MTCI) is designed to monitor vegetation condition via an estimation of chlorophyll content. Its simplicity of calculation, suitability for automation and most importantly, sensitivity to all and notably, high values of chlorophyll content made it a suitable level-2 ESA product. This index effectively combines information on leaf area index and the chloro...

marine environment of the caspian sea, due to extensive human exploitation and discharge of large magnitudes of urban, industrial and agricultural waste, is under extensive pressure. nutrients such as phosphate and nitrate, and other human wastes are introduced into the caspian sea by river inflows and by direct waste dumping threatening marine life and eco system of the sea. high concentration...

In this paper, a study on phytoplankton dynamics and size in the tropical coastal waters of Singapore is presented. Chlorophyll-a levels in the Singapore Strait generally range from 0.4 to 10 μg l–1, with an average value of 1.7 μg l–1. In general, higher chlorophyll concentrations are typically found off the east coast of Singapore, as well as in the shallower, more protected waters of the Joh...

The accumulation of chlorophyll, production of two specific lamellar chlorophyll-protein complexes, onset of O(2) evolution, and detection of P700 were examined in intact Jack bean (Canavalia ensiformis [L.] D.C.) leaves treated with 10(-5)m kinetin or benzyladenine and allowed to green under low (30-35%) and high (80-85%) relative humidity. In contrast to reports of the promotion of chlorophyl...

Phytoplankton distribution changes in the Ariake Sea areas, Japan based on remote sensing satellite data is studied. Through experiments with Terra and AQUA MODIS data derived chlorophyll-a concentration and suspended solid as well as truth data of chlorophyll-a concentration together with meteorological data and tidal data which are acquired 7 months from October 2012 to April 2013, it is foun...

Except for the first stages of illumination, exogenous methyl ester of jasmonic acid (MeJA) inhibited much stronger than abscisic acid (ABA) the accumulation of chlorophyll in excised cotyledons of C. pepo L. (zucchini) exposed to controlled light conditions. Benzyladenine (BA) applied in a combination with MeJA or ABA at equimolar concentrations completely neutralized their inhibitory effect. ...
