- Title: Nitrogen-15 partitioning within a three generation tiller sequence of the bunchgrass Schizachyrium scoparium: response to selective defoliation
- Journal: Oecologia
- Authors: J. M. Welker, D. D. Briske, and R. W. Weaver
- Date: 1987
- Summary: In a controlled environment, at Texas A&M University, researches studied nitrogen partitioning among three generations of tillers, within the bunchgrass Schizachyrium scoparium, as a potential mechanism of herbivory tolerance. Nitrogen-15 was transported from the root-labelled primary tiller to anatomically attached secondary and tertiary tiller generations within 24 hours, based on relative enrichment values. The consistent occurrence of relative enrichment values among shoots and roots of the three tiller generations through time indicate a similar demand for nitrogen within the nondef ...
