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

open access: yes, 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.

The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]

open access: yes, 1994
The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown

Chlorophyll and Chlorophyll Catabolite Analysis by HPLC [PDF]

open access: yes, 2018
The most obvious event of leaf senescence is the loss of chlorophyll. Chlorophyll degradation proceeds in a well-characterized pathway that, although being common to higher plants, yields a species-specific set of chlorophyll catabolites, termed phyllobilins.

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

open access: yes, 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 ...

Mesoscale variability of the Mexican Tropical Pacific using TOPEX and SeaWiFS data

open access: yesCiencias Marinas, 2006
The Mexican Tropical Pacific has oligotrophic characteristics; however, it sustains an abundant biodiversity, mainly because of upwelling promoted by its relatively shallow thermocline, strong winds and mesoscale eddies.

On the link between ocean biota emissions, aerosol, and maritime clouds: Airborne, ground, and satellite measurements off the coast of California [PDF]

open access: yes, 2009
Surface, airborne, and satellite measurements over the eastern Pacific Ocean off the coast of California during the period between 2005 and 2007 are used to explore the relationship between ocean chlorophyll a, aerosol, and marine clouds.

Remote Sensing Inversion of Typical Offshore Water Quality Parameter Concentration Based on Improved SVR Algorithm

open access: yesRemote Sensing, 2023
Chlorophyll a concentration and suspended matter concentration, as typical water quality parameters related to spectral characteristics, are essential for characterizing the degree of eutrophication in water bodies.
