Inter- and Intra-Specific Differences in the Root Respiration Rates of Four Hardwood Species
Abstract:The respiration rates of root tips from clonal propagules of Liriodendron tulipifera L., Acer rubrum L., Salix babylonica L., and S. nigra Marsh. were determined manometrically. One clone of S. nigra differed significantly from the other clones in that species, but no significant intra-specific differences were found among randomly selected clones of the other three species. The root respiration rates of A. rubrum and S. babylonica did not differ significantly; all other species showed significant differences. The average QO2 for L. tulipifera was 3.78, for A. rubrium 5.14, for S. babylonica 5.59, and for S. nigra it was 6.44.
