Prediction method for large diatom appearance in winter with meteorological data and MODIS derived turbidity and chlorophyll-a in Ariake Bay Area in Japan is proposed. Mechanism for large diatom appearance in winter is discussed with the influencing factors, meteorological condition and in-situ data of turbidity, chlorophyll-a data with the measuring instruments equipped at the Saga University ...

Abstract The fish population could expand in a healthy habitat with adequate water quality and fertile conditions. Banten bay estuaries were known as an area high fishing activities source of income for fishermen. Many human occur the vicinity estuaries, which can impact aquatic fertility. This study aims to determine trophic status fourth estuary Bay. Water was sampled estuarine Bay, namely Wa...

Elevated CO2 (eCO2) increase plant biomass and might lead to nutritional losses. The results showed that eCO2 under Fe-deficiency stimulates root dry weight from 0.37–0.80 g plant?1 shoot 0.82–2.10 plant?1, without compromising root/shoot ratio. Besides, improved the chlorophyl content of Fe-deficient plants. However, downregulation photosynthesis, reduction in stomatal conductance transpiratio...

Agriculture aims at increasing production and provision of high quality products to the market. Most of the times, quality is strongly correlated the variety or the hybrid. Specifically, lettuce qualitative characteristics and nutrients appear to vary strongly in different varieties and hybrids. In the current research, lettuce plants were harvested at baby, immature and mature stage in 46, 60 ...

This study was conducted to evaluate the effect of contaminated soil with lead and chromium using three species trees Platanus orientalis, Eucalyptus camaldulensis, Populus nigra as a remediation tool which considers priority restoring method keep healthy support life system for all organisms. The experiment concentrations Pb (200,400, 600 mg.kg-1) levels Cr (100, 200, 300 along control. result...

Combined light spectra and nitrogen (N) availability may modify contents of triterpenoid saponins (TSs) in leaves Aralia elata (Miq.) Seem. In this study, A. seedlings were raised under light-emitting diode red- (26.6% red, 59.9% green, 13.5% blue) green-colours (12.6% 84.6% 2.9% both at a photosynthetic photon flux density about 77.4 µmol m-2 s-1. N was employed low high rates 30 90 mg kg-1, r...

Relation between chlorophyll-a concentration and red tide in the intensive study area of the back of Ariake Sea, Japan in the recent winter seasons is investigated by using MODIS data. Mechanism of red tide appearance is not so clarified. On the other hand, chlorophyll-a concentration can be estimated with satellite remote sensing data. An attempt is made for estimation of the location and size...

Proton electron nuclear double resonance (ENDOR) spectra of P700(+) in spinach chloroplasts and in photosystem I particles have been obtained and compared with the corresponding ENDOR spectrum of monomeric chlorophyl a(+) (Chla(+)) cation radical. The hyperfine couplings for P700(+) can be interpreted in terms of those expected for a monomer Chla(+) radical. The reduction in alpha-carbon spin d...
