Introduction

Jens Hannibal; Jan Fahrenkrug

A revolution in plant modeling in the 1970s highlighted the need for better respiration algorithms. Subsequent research enhanced conceptual insights into processes underlying growth and maintenance respiration. This chapter offers an overview of the most important basic concepts used to partition respiration into energy-utilizing components for growth, maintenance and ion uptake, both with respect to modeling and for experimental measurements.

Conceptual models can offer a simplified representation of the mechanisms of respiratory energy partitioning in plant. Comparing different conceptual models demonstrates that plant growth can be simulated with different equations, each without containing detailed information on the underlying respiratory processes. For that reason, process-based models are more useful to quantify the relative importance of energy-consuming processes and identifying quantitatively important gaps in our knowledge. Allometric modeling is a rapidly developing research area, and seems to offer promising perspectives for the future.

Experimental methods to relate respiration to underlying energy-utilizing components for growth, maintenance and ion uptake may be divided in three distinct approaches: i) correlative or regression approaches, ii) black-box approaches, and iii) process-based approaches. The first method especially has enhanced our insight into the differences between fast- and slow-growing species. Although useful in the past, the second approach is outdated, and should no longer be used. More studies should use process-based approaches to further progress our understanding. Especially combining experimental and theoretical process-based approaches seems to offer interesting perspectives. Our understanding of the relation between the energy-utilizing components with environmental conditions is still limited, but gradually increasing by including environmental conditions in process-based research. In addition to down-scaling by studying energy-utilizing processes in depth, up-scaling as done in allometric modeling may offer valuable insights into our understanding of the use of respiratory energy.
