Root distribution of 'Valencia' orange under traveler gun irrigation
(Empresa Brasil Pesq AgropecBrasiliaBrasil, 2007)
Is the zone of influence colonized by roots of neighboring species? Field tests in a Patagonian steppe
(Academic Press Ltd - Elsevier Science Ltd, 2017-02)
In general, there is more knowledge about aboveground structure and processes than about those belowground. It has been proposed that plants are belowground territorial and root segregation explains species coexistence. ...
Calcium hydroxide root canal dressing. Histopathological evaluation of periapical repair at different time periods.
The objective of this study was to evaluate periapical and apical repair using calcium hydroxide root canal dressings for different lengths of times in teeth with induced chronic periapical lesions. A total of 61 root ...
Microbial distribution in the root canal system after periapical lesion induction using different methods
The aim of this study was to evaluate the microbial distribution in the root canal system after periapical lesion induction in dogs' teeth using different methods. Fifty-two root canals were assigned to 4 groups (n=13). ...
Dynamics of soil exploration by fine roots down to a depth of 10 m throughout the entire rotation in Eucalyptus grandis plantations
(Frontiers Research Foundation, 2013-07-09)
Although highly weathered soils cover considerable areas in tropical regions, little is known about exploration by roots in deep soil layers. Intensively managed Eucalyptus plantations are simple forest ecosystems that can ...
Root-system of peanuts as affected by phosphorus fertilization
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-11-01)
There have been some responses of peanut roots to phosphorus. An experiment was carried out to study peanut root growth and distribution as related to P in the soil. The cultivars Tatu, Oira and Tup4 and the lines FCA 170 ...
A split-pot experiment with sorghum to test a root water uptake partitioning model
Correct modeling of root water uptake partitioning over depth is an important issue in hydrological and crop growth models. Recently a physically based model to describe root water uptake was developed at single root scale ...
Root trunk height as a risk factor for periodontal furcation involvement in maxillary first molars: an in vitro study.
The aim of this study was to correlate the root trunk height from the furcation openings on the buccal, mesial and distal surfaces to the cemento-enamel junction in upper first permanent molars in human beings with risk ...
Vertical distribution of root biomass and soil carbon stocks in forage cropping systems
Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ...
