Summary statistics on energy use efficiency (EUE, Eq. 3) of root growth in wheat obtained from mean values (n = 5) of 16 wheat genotypes. Results are based on data presented in Colombi et al.^2.

		EUE
CR ratio [kJ g−1 CO2-C]	PR [MPa]	Min	Mean	Median	Max
30	0.17	0.555	0.614	0.629	0.656
	0.45	0.455	0.577	0.574	0.648
	0.89	0.443	0.534	0.541	0.594
60	0.17	0.385	0.444	0.459	0.489
	0.45	0.295	0.407	0.402	0.479
	0.89	0.285	0.366	0.371	0.423

Abbreviations: CR ratio = calorespirometric ratio, PR = soil penetration resistance, Min = genotype with lowest EUE, Mean = mean EUE across all genotypes, Median: median EUE across all genotypes, Max = genotype with highest EUE
