The potential of slow phase chlorophyll fluorescence (CF) to predict the physiological status of Pelargonium propagules (seven varieties in 28 different batches) post shipment or post simulated shipment was evaluated. The rooting ability of the cuttings was recorded and used to confirm the results from the CF data. The use of cardboard versus polystyrene packaging and the inclusion of two treat...

Maillard Reaction Products (MRP) was prepared from glucose and glysine heated at 90 ̊C in air circulating oven for 12 hours. The effect of MRP on chlorophyll stability in green peas was investigated. The addition of Maillard Reaction Products (MRP) decreased the loss of chlorophyll a, chlorophyll b and total chlorophyll. The conversion of pheophytin and pyropheophytin was also reduced by the add...

Twenty years ago, the molecular basis for the seasonal disappearance of chlorophyll was still enigmatic. In the meantime, our knowledge on chlorophyll breakdown has grown considerably. As outlined here, it has been possible to decipher the basic transformations involved in natural chlorophyll breakdown by identification of chlorophyll catabolites in higher plants, and with the help of the synth...

In vitro chlorophyll a degradation by horseradish peroxidase in the presence of the resorcinol was investigated in this paper, and the influence of pH and temperature was particularly studied. Chlorophyll a degradation was followed by UV–Vis and HPLC. Chlorophyll a was degraded when hydrogen peroxide was added into reaction mixture containing chlorophyll fraction, horseradish peroxidase, resorc...

The diagnosis model of the cucumber diseases and insect pests was established by laser-induced chlorophyll fluorescence (LICF) spectroscopy technology combined with Back Propagation Artificial Neural Networks (BP-ANN) algorithm in this research. This model would be used to realize the fast and exact diagnosis of the cucumber diseases and insect pests. Four kinds of in-vivo cucumber leaves (heal...

The principal objective of hydrodynamical-biological models is to provide estimates of the main carbon fluxes such as total and export oceanic production. These models are nitrogen based, that is to say that the variables are expressed in terms of their nitrogen content. Moreover models are calibrated using chlorophyll data sets. Therefore carbon 5 to chlorophyll (C:Chl) and carbon to nitrogen ...

This work presents the utilization of MODIS data for mapping chlorophyll spatial distribution along east coast of Malaysia. Four algorithms have involved in this study which were Aiken’ algorithm, Clark-3-Bands algorithm, Gordon algorithm and Normalized Difference Chlorophyll Index (NDCI) algorithm. In this study, the maximum amount of chlorophyll concentration value of 0.38 mg m occurred durin...

Microalgae oil is an optimal feedstock for nutraceutical, pharmaceutical and biodiesel production, but its high levels of chlorophyll limit its large-scale application. To date, few effective approaches have been developed to remove chlorophyll from microalgae oil. The main purpose of this study was to present a preprocessing method of algae oil feedstock (Scenedesmus) to remove chlorophyll by ...
