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 ...
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, ...
Phenological aspects and variation of chlorophylls a and b contents in caryocar-brasiliense camb
(Inst Tecnologia Parana, 2014)
Photosynthetic responses and proline content of mature and young leaves of sunflower plants under water deficit
(2006-03-01)
In mature and young leaves of sunflower (Helianthus annuus L. cv. Catissol-01) plants grown in the greenhouse, photosynthetic rate, stomatal conductance, and transpiration rate declined during water stress independently ...
Spectral irradiance, gas exchange characteristics and leaf traits of Vaccinium corymbosum L. 'Elliott' grown under photo-selective nets
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
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 ...
Indirect method for quantifying the content of photosynthetic pigments in genotypes of dwarf elephant grass
(Editora da Universidade Estadual de Maringá (EDUEM), 2013-03-01)
O objetivo deste ensaio foi determinar equações que indiretamente associem os valores obtidos no medidor de clorofila SPAD-502 aos teores de clorofila e carotenóides de genótipos de capim-elefante anão. Folhas de genótipos ...
Pigments and photosynthesis of understory grasses: Light irradiance and soil moisture effects
(Springer, 2016-03)
Phleum alpinum and Poa pratensis are major forage species that often grow in various environments in Tierra del Fuego, Argentina. To investigate how these species acclimate to the different irradiance of the microenvironments ...
