Results and Discussion A coefficient of 1 means a perfect positive relationship – as one variable increases, the other increases proportionally. 12: 343-346, (1967) (2) Method based on EPA Method 445.0: In vitro determination of chlorophyll a and pheophytin a in marine and freshwater algae by fluorescence. 663) Chlorophyll a: 12.7(A. Duke University, Nicholas School of the Environment and Earth Sciences, Durham, North Carolina . used for estimating chlorophyll-a concentration in various waters. Chlorophyll content was traditionally measured in the laboratory by extracting the chlorophyll itself from a leaf sample using acetone before calculating the chlorophyll concentration by spectrophotometrically measuring absorption at 663 nm and 645 nm. Quantitative estimation of chlorophyll Estimation of chlorophyll and carotene content using the formula in Table 1. showed large variation in their content among the different solvents for both leaf types. 361-385 Marker, A F H. 1977. The difference between the absorbances (A) at 710 and 780 nm [ΔA (710–780 nm)] correlated significantly (r = 0.98) with chlorophyll contents of 0.3–13.4 μg/g fresh weight (gfw).

Two of the most precise estimation models were used to estimate the chlorophyll and total suspended matter concentration. Determine Budget. The use of acetone and methanol in the estimation of chlorophyll in the presence of phaeophytin. Total leaf pigment includes chlorophyll-a, chlorophyll-b and carotenoids that are necessary for photosynthesis process. Typical values for freshwater lakes range 1 - 300mg/L. The cholorophyll content was generally high in septate leaf than aseptate leaf. Chlorophyll a methodologies have changed over the past 25 years, and with each change, the previous chlorophyll estimates became obsolete and non-comparable to the new methods.

An estimator of a population parameter is a rule, formula, or procedure for computing a numerical estimate of an unknown population parameter from the sample values of the observable variables. Chlorophyll extraction by three solvents in three aquatic plants Total chlorophylls of duckweed extracted by 80% acetone, 90% acetone, and 95% ethanol were 0.648 * 0.012 mg g-', 0.860 * 0.008 mg g-', and 0.745 * 0.018 mg g-', respectively. Abstract: The goal of this study was to model the total leaf chlorophyll content (LCCtot) of Gannan navel orange leaves using a field imaging spectroscopy system in the visible and near-infrared domain. The estimation of water quality parameters such as the concentration of TSS (Total suspended sediments) and Chl-a (Chlorophyll-a) from satellite images is strongly depend on the accuracy of atmospheric correction and water quality parameter retrievals algorithms (Ruddick, Ovidio, and Rijkeboer 2000; The chlorophyll amount calculated respectively by following formula with chl-a,chl-b and total chlorophyll as per Arnon (1949) method. The formula for calculating chlorophyll is as follows: Chla A A= ∗ − ∗13.95 665 6.88 649 (2) Chlb A A=24.96* 649 7.32* 665− (3) Chl a b Chla Chlb(+= +) (4) Among them: Chla represents the content of chlorophyll a, Chlb represents the content of chlorophyll b, and Chl a b(+) is the total content of chlorophyll. The chlorophyll extract was transferred to a cuvette and the absorbance was read in a Spectrophotometer at 645 and 663 nm against DMSO blank Chlorophyll a, b, total chlorophyll and chlorophyll a/b ratio were calculated. Total chlorophyll =Chlorophyll ‗a ‗+ Chlorophyll ‗b‘ =0.951 mg. Chlorophyll concentrations are measured by spectrophotometry as: [ Chl a] = 13.43 ( A 663.8 – A 750) – 3.47 ( A 646.8 – A 750) ( nmol mL – 1) [ Chl b] = 22.90 ( A 646.8 – A 750) – 5.38 ( A 663.8 – A 750) ( nmol mL – 1) here [Chl a] and [Chl b] are molar concentrations of chlorophyll a and chlorophyll b, respectively. The "chlorophyll ¿z" values given by the equation of Talling & Driver (1963) for acetone extracts were approximately equal to the values for total chlorophyll a + phaeophytin a given by the equation of Lorenzen (1967).
