Root system characteristics of Marandu palisadegrass supplied with nitrogen and magnesium rates
(Sociedade Brasileira de Zootecnia, 2011)
The development of root system of forage grasses is influenced by the supply of mineral nutrients. The experiment was carried out in a greenhouse in Piracicaba, São Paulo State, with the objective of evaluating the effect ...
Histological events during in vitro rooting of Nothofagus nervosa (Fagaceae)
(Taylor & Francis, 2005-12)
In vitro rooting protocols were previously performed on Nothofagus nervosa to optimise the culture medium and environmental conditions. A qualitative and quantitative tissue differentiation study during adventitious rooting ...
Development of tuberous cassava roots under different tillage systems: Descriptive anatomy
(2015-01-01)
The interaction between the roots of cassava (Manihot esculenta Crantz) and soil physical properties has previously been analyzed. This interaction results in differences in production of plant material and in the ...
Cotton root volume and root dry matter as function of high soil bulk density and soil water stress
(2008-12-01)
Soil compaction reduces root growth, affecting the yield, especially in the Southern Coastal Plain of the USA. Simulations of the root restricting layers in greenhouses are necessary to develop mechanisms which alleviate ...
Calcium hydroxide root canal sealers: Evaluation of pH, calcium ion concentration and conductivity
(1997-12-01)
The calcium hydroxide ionization of four root canal sealers (Sealapex, CRCS, Sealer 26, and Apexit) was studied by measuring conductivity and pH and by conducting atomic absorption spectrophotometry. Samples 6 mm in diameter ...
Effect of the root canal final rinse protocols on the debris and smear layer removal and on the push-out strength of an epoxy-based sealer
(2013-05-01)
The aim of the present study was to evaluate the efficacy of QMiX, SmearClear, and 17% EDTA for the debris and smear layer removal from the root canal and its effects on the push-out bond strength of an epoxy-based sealer ...
Comparative wood anatomy of root and stem in Styrax camporum (Styracaceae)
(Int Assoc Wood Anatomists, 1997-01-01)
Styrax camporum Pohl is a shrub common in the cerrado vegetation of south-eastern Brazil. Root and stem wood in Styrax camporum differ quantitatively and qualitatively. Quantitative differences follow normal expectations: ...

Kinetics of zinc uptake and anatomy of roots and leaves of coffee trees as affected by zinc nutrition
(Taylor & Francis Inc, 2005-01-01)
Zinc (Zn) uptake kinetics and root and leaf anatomy were studied in coffee trees grown in nutrient solutions with or without Zn. Leaves and roots were sampled and cuts were made in the medium part of the leaves and in root ...
Efficacy of four irrigation needles in cleaning the apical third of root canals
(2013-05-06)
This study aimed to evaluate the influence of irrigation needle gauge and design, and the final root canal diameter on the apical cleaning efficacy. Twelve human mandibular incisors were used. At different stages of root ...
