Mycorrhizas and root architecture

Experientia, 1991
Roots function dually as a support system and as the nutrient uptake organ of plants. Root morphology changes in response to the soil environment to minimize the metabolic cost of maintaining the root system, while maximizing nutrient acquisition. In response to nutrient-limiting conditions, plants may increase root fineness or specific root length ...

Advances in root architectural modeling

2021
Root architectural (RSA) models have become important tools in root research and plant phenotyping for studying root traits, processes, and interactions with the environment. The models have been used to simulate how various root traits and processes influence water and nutrient uptake.

Why model root system architecture?

2000
In this short discussion, I shall attempt to classify some of the various models of root system architecture according to the different purposes they can serve. A major objective, which is recurrent in many modelling approaches, was to provide better representations of the root system as an input for uptake models or crop models.

Modelling Root System Growth and Architecture

2000
For any complex system, and particularly for the root system interacting with the rest of the plant and the environment, a model can be a helpful tool for synthesising knowledge to produce more global representations and for testing hypotheses on the interacting mechanisms derived from experimental results.

Root architecture and tree stability

Plant and Soil, 1983
Root anchorage is discussed with a view to determining the optimum use of root material for enhanced stability. Field observations were made on Sitka spruce root systems while lateral forces were applied to the stem with a winch to pull the tree over. Measurements included the applied force, angles of inclination, soil and root movement, timing of the ...

Pre-Breeding to Change Sugarbeet Root Architecture .

Journal of Sugarbeet Research, 1993
Economic improvement of sugarbeet (Beta vulgaris) field production and processing can be enhanced if traditional architecture of the sugarbeet is modified to a smooth root (SR) beet. Root shape of sugarbeet is a multigenic character and several generations of breeding are needed to reach any degree of homozygosity.

Arabidopsis arenosa root architecture

A project conducted within the K. Bomblies lab at ETHZ to examine root architecture of A. arenosa. Phenotypes for 14 populations were assayed including lateral & adventitious roots, direction of growth, upside-down germination, roots lifting off of the plate, and starch levels in root tips.

Root Architecture and Nutrient Acquisition

2005
Excavation of plants from soil readily reveals that the shape of root systems is quite complex. The elegant drawings of Kutschera (e.g., Fig. 7.1; Kutschera and Lichtenegger 1992), collected painstakingly over many years of fieldwork, provide beautiful illustrations of the complexity and diversity of the spatial configuration of root systems, or ‘root ...
