Respiratory costs and rate of protein turnover in the roots of a fast‐growing ( Dactylis glomerata L.) and a slow‐growing ( Festuca ovina L.) grass species

Abstract

this abstract are based on the assumption that 50% recycling of the 14C-labelled leucine took place in the Protein turnover is generally regarded as one of the roots of both grass species. most important maintenance processes in plants in terms of energy requirements.
