REACTIVITY OF CHLOROPHYLL a/b-PROTEINS AND MICELLAR TRITON X-100 COMPLEXES OF CHLOROPHYLLS a OR b WITH BOROHYDRIDE [PDF]

, 1989
The reaction of several plant chlorophyll-protein complexes with NaBH4 has been studied by absorption spectroscopy. In all the complexes studied, chlorophyll b is more reactive than Chi a, due to preferential reaction of its formyl substituent at C-7 ...

Relationship Between Physiological Characteristic and Bean Quality on Some Cocoa Clones (Theobroma Cacao L.) [PDF]

, 2015
Photosynthesis is one of the physiological process that influence the bean weight and this process related with the efectiveness of the stomata character and chlorophyll content in the leaves.

Satellite-derived global chlorophyll-a anomaly products

International Journal of Applied Earth Observations and Geoinformation, 2021
We describe our effort to produce the first-ever near-real-time (NRT) global daily chlorophyll-a (Chl-a) anomaly products that can be used to detect and identify algae blooms from satellite ocean color measurements such as those from the Visible Infrared

Relationship between chlorophyll a pigment and algal geometric biovolume determination in a floodplain lake (Ciénaga Ayapel, Córdoba-Colombia)

Revista Facultad de Ingeniería Universidad de Antioquia, 2012
The estimation of biomass of planktonic algae can be done by two methods, the quantification of geometric biovolume and chlorophyll a. This work which considers as environmental scenario the Ayapel-Cordoba flood-plain lake, introduces (presents) the two

Chlorophyll a fluorescence as a tool to monitor physiological status of plants under abiotic stress conditions

Acta Physiologiae Plantarum, 2016
Plants living under natural conditions are exposed to many adverse factors that interfere with the photosynthetic process, leading to declines in growth, development, and yield.

High throughput analysis of leaf chlorophyll content in sorghum using RGB, hyperspectral, and fluorescence imaging and sensor fusion

Plant Methods, 2022
Leaf chlorophyll content plays an important role in indicating plant stresses and nutrient status. Traditional approaches for the quantification of chlorophyll content mainly include acetone ethanol extraction, spectrophotometry and high-performance ...

Average seasonal changes in chlorophyll a in Icelandic waters [PDF]

, 2009
The standard algorithms used to derive sea surface chlorophyll a concentration from remotely sensed ocean colour data are based almost entirely on the measurements of surface water samples collected in open sea (case 1) waters which cover ~60% of the ...

Aggregation Of Chlorophyll a Probed By Resonance Light Scattering Spectroscopy [PDF]

, 1995
We report the resonance light scattering (RLS) spectra of chlorophyll a aggregated in a 9:1 solution of formamide and pH 6.8 phosphate buffer. The aggregate formed after 2 h of mixing, referred to as Chl(469), shows a strong scattering feature at 469 nm (
