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 Heidelberg, 2019-08-01)
Leaf chlorophyll (chl) and protein distribution were analyzed throughout grain flling in four modern maize hybrids with contrasting senescence behavior, at three diferent canopy levels and at low-N (LN, 18 kg N ha−1) and ...
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 ...

Estimativa do estado nutricional de arroz irrigado por alagamento
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2007-02-15)
The difficulty to predict the intensity of soil properties alterative by soil flooding frequently makes the interpretation of the soil analysis results inaccurate when considering nutrients availability to the plants. ...
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 ...

Patterns of physiological parameters and nitrogen partitioning in flag leaf explain differential grain protein content in rice
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021-11)
The grain protein content (GPC) in rice is low, and more efforts with agronomic and molecular approaches were performed to increase them. However, the rice research focusing on the plant physiological behaviour that modulates ...
