Root and shoot interactions in a tropical integrated crop–livestock–forest system
(2020-05-01)
Integrated crop–livestock–forest systems (ICLFS) have potential advantages compared to monoculture, but most studies quantifying plant biomass in integrated production systems, have quantified only the aboveground component ...
Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas
(2021-01-01)
Fire is a fundamental ecological factor in savannas because it affects vegetation dynamics and ecosystem functioning. However, the effects of fire on below-ground compartments, including biomass and root traits, and their ...
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.
(2002-03-01)
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
(2008-12-01)
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 ...
Future paths for the ‘exploitative segregation of plant roots’ model
(2021-01-01)
The exploitative segregation of plant roots (ESPR) is a theory that uses a game-theoretical model to predict plant root foraging behavior in space. The original model returns the optimal root distribution assuming exploitative ...
Canal preparation and filling techniques do not influence the fracture resistance of extensively damaged teeth
(2014-01-01)
The purpose of this study was to assess the fracture resistance of extensively damaged teeth after two root canal preparation techniques (hand and rotary files) and after two filling techniques (active and passive compaction). ...
