Abstract of Research Proposal

Canopy architecture is a key determinant of fractional interception and radiation use efficiency - both crucial to the capacity of crops to exploit the UK’s high productivity environment, and hence to competitiveness in world markets. In wheat, canopy architecture has also been shown to be a key determinant of ‘resistance’ to disease and lodging, and hence the need for agrochemical input. Understanding of the canopy traits required to optimise light interception and conversion, and disease and lodging resistance has improved substantially through recent work. In some cases the structural requirements agree, but in other cases there are conflicts between the ideal canopy for light interception and the ideal canopy for low agrochemical input. The objective of this project is to address DEFRA’s policy aim to reconcile the competitiveness and environmental impact of arable production, by producing a rational basis for the design of canopy ideotypes for UK environments. The project will develop a framework for the purpose of integrating existing parsimonious mathematical functions describing crop growth, light interception, disease escape and lodging resistance. This will be published as a review article in a peer reviewed journal. The first task must be to properly demonstrate that key physiological and epidemiological processes affecting crop growth and yield can be linked through comparable quantitative measurements to yield accumulation. Mechanistic models might then be constructed to explore canopy design with the aim of optimising the production and environmental benefits. Development of such an approach will be valuable for understanding the consequences of changes in canopy structure and thus will bridge the ‘phenotype gap’ between knowledge of the plant genome and understanding of the phenotypes required for commercial exploitation, which will otherwise constrain progress.

Summary of Objectives

1. To integrate understanding of canopy structure effects on light capture, disease escape and lodging, by development of a hypothetical framework and identification of common units for comparison of the impact of traits on light capture, escape and lodging.

2. To develop and integrate model of canopy structure with extant crop growth model.
