Abstract/Contents:"When supplies of water and mineral nutrients are adequate, crop growth is determined by the amount of solar radiation intercepted over the season and the efficiency of its conversion into dry matter. Soil factors such as drought, nutrient availability, salinity, waterlogging, mechanical impedance and root-infecting pathogens can be a serious constraint to yield and operate through effects on the growth, photosynthetic activity and duration of the canopy, and on the partitioning of biomass to harvested parts. One approach to overcome restrictions on the canopy and enhance yield is to modify root systems so that they are better suited to the prevailing soil conditions. This might be achieved through genetic improvement or by cultural practices. A better understanding of the physiology of root systems is required to identify appropriate root traits for selection or management. Not only should this encompass considerations of the function of roots in the capture of water and nutrients and the provision of anchorage, but also new concepts about the role of chemical signals in the regulation of the canopy. Greater emphasis must be placed on field-based research. The growth, development and activity of roots in the field can differ markedly from those in most laboratory experiments, because field soils are more complex in structure and differ in their biological, chemical and physical properties. It is argued that a decline in structure and differ in their biological, chemical and physical properties. It is argued that a decline in field-based research of crop root systems, as seen in the UK over the last 15-20 years, could, if allowed to continue, generate a skills gap which may undermine future exploitation of discoveries made at the cell and molecular level."
