Chlorophyll Degradation and Formation of Colorless Chlorophyll Derivatives during Soybean (Glycine max L. Merill) Seed Maturation
(AMER CHEMICAL SOC, 2009)
The natural chlorophyll degradation results in noncolored chlorophyll catabolites (NCCs), but there are controversies if these are the final products. The formation and degradation of NCCs during soybean seed (Glycine max ...
Phenological aspects and variation of chlorophylls a and b contents in caryocar-brasiliense camb
(Inst Tecnologia Parana, 1993-03-01)
There were detected variations of chlorophylls a and b during the senescence leaves period of Caryocar brasiliense Camb in the Corumbatai cerrado vegetation, State of São Paulo. The highest peak of total chlorophylls a and ...
Análise não destrutiva de pigmentos fotossintéticos em folhas de gergelim
(Universidade Federal da Paraíba (UFPB) Ccsa, 2012-01-01)
The study aimed to relate the photosynthetic pigments, which were extracted in a laboratory and the readings were obtained by the portable chlorophyll meter ClorofiLOG 1030, by using mathematical models in sesame leaves. ...

(2012-01-01)
The study aimed to relate the photosynthetic pigments, which were extracted in a laboratory and the readings were obtained by the portable chlorophyll meter ClorofiLOG 1030, by using mathematical models in sesame leaves.This ...
Nitrogen nutrition of guava trees in response to byproduct of fruit processing
(Taylor & Francis Inc, 2016-01-28)
Studies of the effect of organic fertilization of perennial crops are scarce due to the time necessary for the plants to present the first results. The objective of this study was to assess the leaf nitrogen (N) content, ...
Indirect measurement of photosynthetic pigments in the leaves of Jatropha curcas
(2013-03-01)
The aim of this work was to generate mathematical models capable of identifying photosynthetic pigments and soluble proteins from the leaves of Jatropha curcas using the relationship between classical readings performed ...
Anatomical and physiological aspects of cucumber graft
(2018-01-08)
The grafting of two cucumber scions [Cucumis sativus L.]—Taiko hybrid and Tsuyoi hybrid— onto a Tropical hybrid pumpkin rootstock (Cucurbita moschato L.) was studied. The study was conducted in a greenhouse. Plants grafted ...
Photosynthesis, Chlorophylls, and SPAD Readings in Coffee Leaves in Relation to Nitrogen Supply
(TAYLOR & FRANCIS INC, 2009)
The export of nitrogen (N) from senescent plant parts is important for the efficient use of this macronutrient. The objective of this study was to establish correlations among the photosynthetic pigment content, total N, ...
PARAMETERS FOR THE STANDARDIZATION OF CHLOROPHYLL AND ASSESSMENT OF PS II QUANTUM EFFICIENCY FOR AVOCADO (Persea americana Mill)
(Univ Federal Uberlandia, 2017-07-01)
The standard physiological parameters for assessing stress physiology, of plants, such as chlorophyll index and photosystem II fluorescence, are essential for measuring reactions of plants to stress conditions. To help ...
Relations among pigments, color and phenolic concentrations in the peel of two Gala apple strains according to canopy position and light environment
(ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2013)
