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 ...
Doses de Nitrogênio na Produção de rabanete fertirrigado e determinação de clorofila por medidor portátil nas folhas
(2010-12-01)
The relative chlorophyll determination is used to predict the need for nitrogen fertilization aiming to increase production in various cultures. The objective of this study was to evaluate the soil nitrogen dose response ...

Leaf protein allocation across the canopy and during senescence in earlier and later senescing maize hybrids, and implications for the use of chlorophyll as a proxy of leaf N
(Springer, 2019-09)
Leaf chlorophyll (chl) and protein distribution were analyzed throughout grain filling in four modern maize hybrids with contrasting senescence behavior, at three different canopy levels and at low-N (LN, 18 kg N ha−1) and ...
Instantaneously measured traits may detect non-plastic ecophysiological performances in response to drought, explaining distributions of Styrax species in the Cerrado
(2013-08-12)
We analyzed the differences between irrigated and non-irrigated plants of three congeneric Styrax species that present distinct distribution patterns in the physiognomies of the Cerrado vegetation in Brazil. Styrax ferrugineus ...

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. ...
