Root systems of forest tree species and their soil-conservation functions on the Krušné hory Mts. slopes disturbed by mining
root system architecture soil properties
2015/3/5
The paper describes the root system architecture of the forest tree species Fagus sylvatica L., Quercus robur L., Pinus sylvestris L., Carpinus betulus L., Acer platanoides L., and Alnus glutinosa (L....
Effects of pressure on the root systems of Norway spruce plants (Picea abies[L.] Karst.)
root growth stress pressure RAI Picea abies(L.) Karst
2015/2/6
Roots are stressed quire often under natural conditions, e.g. when considering sloping terrain, layers of fluvial deposits, huge layers of melting snow, load of heavy forest machinery during logging a...
Distribution of archaeal and bacterial tetraether membrane lipids in rhizosphere-root systems in soils and their implication for paleoclimate assessment
GDGT rhizoplanes roots revised index of methylation of branched tetraethers estimated temperature
2017/4/11
Branched and isoprenoidal glycerol dialkyl glycerol tetraethers (GDGT) are abundant in soils, but little is known
about the presence of branched GDGT in rhizosphere-root systems versus bulk soils, an...
A study on multiple zeta values from the viewpoint of zeta-functions of root systems
multiple zeta values zeta-functions of root systems Number Theory
2012/5/9
We study multiple zeta values (MZVs) from the viewpoint of zeta-functions associated with the root systems which we have studied in our previous papers. In fact, the $r$-ple zeta-functions of Euler-Za...
We introduce and study a combinatorially defined notion of root basis of a (real) root system of a possibly infinite Coxeter group. Known results on conjugacy up to sign of root bases of certain irred...
Varietal Differences of Root Systems in Winter Wheat Seedlings
Root length Root system Spread of root system Triticum aestivum L Varietal differences Winter wheat
2009/7/30
Varietal differences in root system morphology in winter wheat (Triticum aestivum L.) were investigated using seed pack growth pouches in a greenhouse. Different genotypic cultivars, shorter B-288 D f...
Fractal Geometry in Root Systems:Quantitative Evaluation of Distribution Pattern
Fractal Root box Root length Root morphology Root system
2009/7/28
In order to describe root distribution quantitatively, fractal analysis was applied to root systems. Root systems of soybean and garden pea seeldings grown in narrow root boxes (30×41×2 cm) were sampl...
Comparison of Root Systems among Rice Cultivars by Simplified Investigation Methods
Cultivar difference Lodging tolerance Rice Root distribution Root profile Root projection area
2009/7/23
Simplified investigation methods of root systems in Japanese and American rice cultivars were examined using photographic recording methods and image analysis on a personal computer. In order to photo...
Genetic Opportunities to Improve Cereal Root Systems for Dryland Agriculture
Breeding Root growth Root health Root physiology Water uptake Wheat
2009/7/21
Understanding the major limitations to root growth is very important if we are to maximize water and nutrient use and increase yields. Limitations may be insufficient rooting depth, root diseases, nut...

A New Approach to Crop Root Systems with Quantitative Analysis of the Root Depth.
Varietal Differences of Root Systems in Tea-Rooted Cutting
Camellia sinensis L. Cutting Root system Tea Varietal difference
2009/7/16
Varietal differences in root system morphology in tea-rooted cuttings were examined by using a cylindrical net (radius of 3 cm) in a nursery bed. To determine the spatial distribution of the root, 11 ...
Selection of Wheat Experimental Lines with Deep and Shallow Root Systems Based on the Growth Angle of Seminal Roots(Crop Morphology)
Basket method Doubled haploid Improved monolith method Root depth index Root length density
2009/7/15
Deep-rooted and shallow-rooted doubled-haploid lines of wheat were selected based on the root growth angle of seedlings. First, 129 normal growth doubled haploid lines were primary selected from the 5...
