Book 2000le in the supply of resources for growth, and yet we have a relatively poor understanding of how they function in the natural soil environment. Dr. B6hm began the Preface of his standard text on root research methods (B6hm 1979) with the comment: "Root research under natural jield conditions is a st

Sampling Strategies, Scaling, and Statistics,r. Detailed information on root architecture may be of interest in constructing mathematical models of root growth (see Chap. 4), in comparing the structure and function of root systems of different species or genotypes (e.g. Fitter and Stickland 1991), and in evaluating root responses to environmental conditions (e.g. Robinson 1994).

Control and Measurement of the Physical Environment in Root Growth Experiments,h to plant growth in varying environments, including growth of the root system. This leaves a large, and nearly empty ‘ecological niche’ for studies carried out at the whole plant level, which analyse root system growth as a function of the environment. This chapter provides guidance on how to manipulate the rooting environment.

The Measurement and Analysis of Fine Root Longevity, will also allow us to make more informed assessments of how any deleterious effects may be ameliorated. One of the important research targets for terrestrial ecosystems is to understand biogeochemical cycles, as it is these fluxes (and the processes which drive them), which are fundamental to ecosystem stability.

Assessing the Ability of Roots for Nutrient Acquisition,the rhizosphere, and (3) ability for nutrient uptake through the plasma membranes (for reviews see Barber 1984; Clarkson 1985; Marschner 1995). The relative importance of these factors for nutrient acquisition is dependent on environmental conditions and the specific nutrient, particularly its chemical availability and mobility in the soil.

Anatomy and Histology of Roots and Root-Soil Boundary,necessary to obtain structural information on the inner (anatomy and histology) and outer (morphology) parts of roots. This chapter gives an overview of methods to obtain information on anatomical and histological as well as morphological (root hairs and mycorrhiza) properties of roots. The methods
