Root growth and distribution of two short-season rice genotypes
Root growth dynamics of lowland rice ( Oryza sativa L.) throughout the growing season are poorly understood. A field experiment was conducted in 1987...
-
Root production and root turnover in two dominant species of wet heathlands
Root biomass production, root length production and root turnover of Erica tetralix and Molinia caerulea were estimated by sequential core sampling...
-
Effects of soil type on soybean crop water use in weighing lysimeters
Accurate estimation of crop evaporation from a range of soil types is fundamental to the continued improvement of irrigation management. In this...

A simulation model of the three-dimensional architecture of the maize root system
In order to study the nutrient and water uptake of roots in situ , we need a quantitative three-dimensional dynamic model of the root system...

Root systems
Although root system studies are generally conceded to be important, the difficulties in such study are sufficiently daunting that root systems have...

Rates of rhizodeposition and ammonium depletion in the rhizosphere of axenic oat roots
A multiple split root chamber and artificial soil were developed which allowed for maintenance of axenic conditions and for the isolation of soil...

Response of two perennial grasses to water availability in different habitats related to successional change under Mediterranean climate conditions
Water is the main factor limiting plant growth under mediterranean climate conditions. Relationships between drought duration and plant distribution,...

Approaches for studying the function of deep root systems
The distribution of roots in a soil column is such that root biomass and length generally decrease abruptly with depth (Böhm 1979). Most studies of...

A new dimension to observations in minirhizotrons: A stereoscopic view on root photographs
With a stereoscope, as used for the inspection of aerial photographs, sequential photographs of roots obtained by the endoscope method from...

Root and Soil Microbial Interactions which Influence the Availability of Photoassimilate Carbon to the Rhizosphere
Extensive plant root systems, reported to achieve lengths of up to 71,000 m per wheat (Triticum aestivum L.) plant (Pavlychenko 1937)...

A comparison of methods, including angled and vertical minirhizotrons, for studying root growth and distribution in a spring oat crop
Four methods of measuring root distribution in a spring oat crop were compared: minirhizotrons installed vertically, minirhizotrons installed at an...

Morphogénèse des systèmes racinaires des semis et boutures de chêne pédonculè
Primary roots are orthogeotropic on seedlings (Fig. 3) and on cuttings taken from seedlings (Fig. 23 to 25) and semi-plagiogeotropic on cuttings...
