THE INFLUENCE OF STRONG AND WEAK ACID UPON AGGREGATION AND PHEOPHYTINIZATION OF CHLOROPHYLL A AND B [PDF]
Indonesian Journal of Chemistry, 2010 Chlorophyll is green pigment that can be found in plant chloroplast. Higher plants usually have two kinds of chlorophylls, chlorophyll a and b. These green pigments are easily degraded by temperature, light intensity, oxygen, acid, and water.

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

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 ...

Quantification of chlorophyll a, chlorophyll b and pheopigments a in lake sediments through deconvolution of bulk UV–VIS absorption spectra [PDF]
, 2020 Assessments of aquatic paleoproduction and pigment preservation require accurate identification and quantification of sedimentary chlorophylls. Using chromatographic techniques to analyze long records at high resolution is impractical because they are ...

Spatial Variation of Leaf Chlorophyll in Northern Hemisphere Grasslands
Frontiers in Plant Science, 2020 Chlorophyll is the molecular basis for the function of photosystems and is also a promising tool for ecological prediction. However, the large-scale patterns of chlorophyll variation in grasslands remain poorly understood.

Effect of The herbicide Pendimethalin on The Chlorophyll Content in Zea mays l. and Gossypium hirsutum l. Seedlings [PDF]
Journal of Plant Production, 2016 Foliar application of pendimethalin herbicide (5 ppm) to three weeks old seedlings of Zea mays L. and GossypiumhirsutumL. resulted in a decreasing trend of chlorophylls a an b in both seedlings compared to controls.
