Ruzigrass root persistence and soybean root growth
(Springer, 2019-09-01)
Aims Cropping systems using forage grasses as cover crops have been effective in soil conservation and nutrient cycling, but root persistence of ruzigrass (Urochloa ruziziensis) is significant, and may impair root growth ...
Periapical repair after root canal filling with different root canal sealers
(2009-12-01)
The aim of this study was to evaluate periapical repair after root canal filling with different endodontic sealers. Sixty four root canals from dog ́s teeth were filled, divided into 4 groups (n=16). Root canals were ...
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 ...
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 ...
Consequences of mixing Acacia mangium and Eucalyptus grandis trees on soil exploration by fine-roots down to a depth of 17 m
(Springer, 2018-03-01)
Fine-root functioning is a major driver of plant growth and strongly influences the global carbon cycle. While fine-root over-yielding has been shown in the upper soil layers of mixed-species forests relative to monospecific ...
The effect of root exudates on root architecture in Arabidopsis thaliana
(Springer, 2011-07)
Root architecture is of key importance for plant nutrition and performance. It is known that root architecture is determined by genetics and environmental conditions. The aim of the present study was to evaluate if root ...
In Vitro Macroscopic and Endoscopic Analysis of Three-Rooted Maxillary Premolars and Two-Rooted Mandibular Premolars in the Same Individual: a Case Report
(SOC CHILENA ANATOMIATEMUCO, 2012)
The recent addition of endoscopy in dental practice has enabled clinicians to have an excellent view of the operative field, yielding highly successful visualization of anatomical structures that are difficult to access, ...
Assessment of the apical seal of root canals using different filling techniques.
(2009-12-01)
The aim of this study was to investigate the apical leakage of roots filled by three different gutta-percha techniques: lateral condensation, Tagger's hybrid and E&Q Master. Forty-two extracted single-rooted teeth were ...
Tissue response to an epoxy resin-based root canal sealer
(Munksgaard Int Publ Ltd, 1999-02-01)
The objective of the present study was to evaluate two different types of root canal sealers: AH Plus (an epoxy resin-based sealer) and Fill Canal (a zinc oxide-eugenol based sealer). A total of 34 root canals with vital ...
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 ...
