The Determination of Relative Elemental Growth Rate Profiles from Segmental Growth Rates (A Methodological Evaluation) [PDF]
Plant Physiology, 1997 Abstract Relative elemental growth rate (REGR) profiles describe spatial patterns of growth intensity; they are indispensable for causal growth analyses. Published methods of REGR profile determination from marking experiments fall in two classes: the profile is either described by a series of segmental growth rates, or calculated as the

Growth analysis of an aged Turkey oak coppice under conversion into high forest
Annals of Silvicultural Research, 2020 Most Italian research concerning the conversion of coppices analyse growth response at the stand level and adopt absolute growth as reference metric. Nonetheless, inter-individual interactions are lost when averaging tree level information at the stand ...

Systems, 2014 Early studies showed the metabolic rate (MR) of different-sized animals was not directly related to body mass. The initial explanation of this difference, the “surface law”, was replaced by the suggestion that MR be expressed relative to massn, where the

RELATIVE GROWTH RATE: THE TWO-PHASE CURVE [PDF]
HortScience, 1990 The growth and development patterns of fruit have been studied for many years and it has become traditional to think of peaches as having a double sigmoid pattern with three main stages fruit growth. This concept is primarily based on analyses of fruit absolute growth rates An alternative approach is to express growth on a relative growth rate (RGR ...
