Although chlorophyllous and carotenoid pigments may be extracted readily in organic solvents, for many algae, extraction is not complete unless the cells are ruptured. by using above formula. 0000014743 00000 n 1. 0000003766 00000 n This occurrence is due to the fact that chlorophyll a is the principal pigment in microalgae while chlorophyll b is the accessory pigment that collects the energy to pass on to chlorophyll a. Chlorophyll a absorbs well at a wavelength of about 450 nm but its primary absorption is at 675 nm in the long red wavelengths. 0000004803 00000 n Unfortunately, the Arnon equations are not particularly accurate (Porra, 2002).

The chlorophyll index is used to calculate the total chlorophyll content of the leaves. The use of acetone and methanol in the estimation of chlorophyll in the presence of phaeophytin. In terms of the spatial scale issue, previous studies have estimated chlorophyll contents using single-scale (leaf- or canopy-scale) RS data Asner and Martin, 2008). Faisal and Anis .

It may be due to that reason that septate leaves were mature while the aseptate leaves were not fully matured [24]. The ΔA (570–780 nm) correlated significantly (r = 0.97) with lycopene contents of 0.2–46.7 μg/gfw. 2.2. Content Guidelines 2.
