Exogenous auxin improves root morphology and restores growth of grafted cucumber seedlings

open access: yesHorticultural Science, 2017
The aim of this study was to investigate the effects of exogenously applied auxin over the rootstock cuttings on root morphology parameters and stand establishment rate of salt-stressed cutting grafted cucumber seedlings.

Soybean Root Growth in Response to Chemical, Physical, and Biological Soil Variations

open access: yesFrontiers in Plant Science, 2021
Environmental conditions affect crop yield, and water deficit has been highlighted by the negative impact on soybean grain production. Radicial growth in greater volume and depth can be an alternative to minimize losses caused by a lack of water ...

Genetic control of root weight, root volume and root to shoot weight ratio in peas [PDF]

open access: yes, 1988
The genetic control of root weight, root volume and root to shoot weight ratio was studied in peas /Tisum sativum L.) at flowering. The four populations used were developed from crosses between lines and cultivars differing in size of the root systems ...

Root System and Its Relations with Soil Physical and Chemical Attributes in Orange Culture

open access: yesApplied Sciences, 2021
Citrus companies have sought and developed alternative systems of tillage or implanting orchards so as not to significantly alter the physical and chemical attributes of the soil and, consequently, the root development of plants.

On Volume Functions of Special Flow Polytopes Associated to the Root System of Type $A$ [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2020
In this paper, we consider the volume of a special kind of flow polytope. We show that its volume satisfies a certain system of differential equations, and conversely, the solution of the system of differential equations is unique up to a constant multiple.

Descendant root volume varies as a function of root type: estimation of root biomass lost during uprooting in Pinus pinaster [PDF]

open access: yesFrontiers in Plant Science, 2013
Root systems of woody plants generally display a strong relationship between the cross-sectional area or cross-sectional diameter (CSD) of a root and the dry weight of biomass (DWd) or root volume (Vd) that has grown (i.e., is descendent) from a point.

Aortic Root Volume and Geometry: Ready for Clinical Application? [PDF]

open access: yesJournal of Cardiovascular Ultrasound, 2011
REFER TO THE PAGE 128-133 Real-time 3-dimensional echocardiography (RT3DE) is a useful imaging modality that can be easily performed in the clinical practice, and has been proven to be applicable in measuring the real volumes of cardiac chambers such as left ventricle,1-3) left atrium,4),5) and right ventricle,6),7) without geometric assumption.

Evaluation of morphological characteristics in Venezuelan maize (Zea mays L.) genotypes under drought stress Avaliação de características morfológicas em genótipos de milhos venezuelanos sob estresse de água

open access: yesScientia Agricola, 1994
A greenhouse experiment was carried out to evaluate the responses among 10 maize (Zea mays L.) genotypes under drought stress. Seeds were planted in washed sand in plastic pots.

Range unit root tests [PDF]

open access: yes, 2003
Since the seminal paper by Dickey and Fuller in 1979, unit-root tests have conditioned the standard approaches to analyse time series with strong serial dependence, the focus being placed in the detection of eventual unit roots in an autorregresive model
