monly used instruments is a Minolta SPAD (soil plant analysis development) meter. The SPAD meter measures the difference in light absorption at 430 and 750 nm (Wood et al., 1992). The former is the transmittance peak for chlorophyl ‘a’ and ‘b’, and the latter is in the near-infrared region. The instrument converts the difference in light absorption at these two wavelengths into a numerical SPAD...

Derivatives of chlorophyl, e.g. Fe-chlorin e6-Na, alpha, beta, gamma, delta-Tetraphenylporphine-tetrasulfonic acid disulfonic acid salt tetrahydrate (Fe-TPPTS) and alpha, beta, gamma, delta-Tetrakis (4-N-trimethylaminophenyl) porphine, tetra (p-toluensulfonate (Fe-TTMAPP), express SOD mimicking activity. Examination was made of suppressive effects of human cancer cell lines by derivatives of ch...

Endophytic fungi in lately was getting a lot of attention agriculture. Besides being able to increase plant resistance against pest organism, it has also the ability stimulate germination and pant growth. One endophytic tested its research Beauveria bassiana from isolate Wheat, Coffeae, Cacao entomopatogen fungus Leptocorisa acuta insect. The aim this know some isolates effect on chlorophyll co...

Sea-truth water sampling campaigns were carried out in the Johore Strait, Singapore from Dec 1996 to Dec 1998, partially funded by NASDA-ESCAP for utilization of ADEOS OCTS data. Water leaving radiance and reflectance data were collected together with coincidental measurements of water quality parameters, including the total suspended solid (TSS) and the chlorophyl-a (Chl-a) loadings. Results o...
