Table I.

Average coefficients of variation (CV) for dry mass, C and N concentration, and the fraction of predefoliation C and N in regrowing tillers of perennial ryegrass

Parameter CV
%
Dry mass (g/tiller) 14.2
C concentration (g/g dry mass) 1.6
N concentration (g/g dry mass) 6.1
Fraction of predefoliation C (g C/g C) 2.9
Fraction of predefoliation N (g N/g N) 3.4

Average CV was calculated from the CVs of sampling date × genotype combinations.
