Table 2.
The temperatures (LT50) and percent electrolyte leakage (LEL50) corresponding to 50% rhizome mortality in Miscanthus × giganteus and three genotypes of Spartina pectinata harvested in the autumn/winter, and spring trialsDifferent letters indicate significant contrast differences between genotypes (P<0.01). Genotypes (as model coefficients) were set as the model intercept and contrasted against each of the other genotypes.
