The form and generality of the biomass–density relationship, especially during self‐thinning of crowded stands, have been intensively debated in recent years. All models of self‐thinning assume that the trajectory is independent of the initial pre‐thinning density, so populations differing in initial density can be analysed together. As plant allometry is a determinant of the self‐thinning trajectory, and competition alters plants' allometric growth, initial density may have consequences for… 
Stage-dependent plasticity in biomass allocation and allometry in response to population density in Abutilon theophrasti: a step forward to understanding the nature of phenotypic plasticity
How plants respond to density via modular plasticity is obscure, probably because relevant studies using covariance analysis (ANCOVA) and allometric analysis rarely focus on multiple stages of plant
Influence of population density on morphological traits and allometric growth of Corispermum macrocarpum
The results showed that density strongly affects the plant architecture, and the biomass of all organs decreased significantly with an increase in density, which is consistent with the prediction of optimal allocation theory in the context of moisture, nutrient, and light limitation.
The significance of biomass allocation to population growth of the invasive species Ambrosia artemisiifolia and Ambrosia trifida with different densities
High input to the stem is an important means to regulate the growth of the two species to cope with different densities, and these two species can ensure reproductive success and produce appropriate seed numbers and maintain a stable population over time.
Morphological plasticity in response to population density varies with soil conditions and growth stage in Abutilon theophrasti (Malvaceae)
Investigating whether and how soil conditions and plant growth stage affected plant responses to density in a variety of traits under field conditions demonstrated that density–plasticity was inherently complex, including multiple responsive trends within and among traits, and revealed that the ability of the plants to adapt to variation in density via responses of various modular traits has been underestimated.
Dividing the pie: A quantitative review on plant density responses.
A meta-analysis of responses of even-aged mono-specific stands to population density quantifies how much both plant biomass and phenotypic traits change with a doubling in density, suggesting that at high density, shading affects plants more than nutrient depletion.
Root morphological responses to population density vary with soil conditions and growth stages: The complexity of density effects
Root allocation increased, decreased, or canalized in response to density, depending on soil conditions and stages of plant growth, indicating the complex effects of population density, including both competitive and facilitative effects.
Growth characteristics of mangrove seedling in silvofishery pond – the allometric relationship of height, diameter and leaf abundance
Mangrove seedling growth is varied among species and growth environment, and the growth of seedling height ofAvicennia in the mixed structure was significantly affected by its diameter growth and the number of leaves of Avicennian in single structured was significant affected byIts diameter.
The impact of human activity on the biomass allocation of a medicinal herbaceous species in an agroforestry system of Southwest China
It is concluded that a C. teeta-based agroforestry system could ensure sustainable use of this medicinal plant because of the stable biomass allocation to the salable rhizome organs.


Size symmetry of competition alters biomass–density relationships
Experimental evidence is provided that morphological plasticity of wild–type populations decreases the size asymmetry of competition for light and thereby decreases density–dependent mortality, which results in more biomass at a given density under size–symmetric compared with size–asymmetric competition.
Density-dependent Mortality Induced by Low Nutrient Status of the Substrate
It is argued that root competition became sufficiently intense to cause the density-dependent mortality seen at the F0-fertility level, with little contribution of shoot competition to mortality.

A review of several experiments using the one species grown at different fertility levels was undertaken to look for any mechanisms that might account for the different patterns observed, and found that the critical difference between whether populations followed a common or different line was the way in which competition developed in the stands as biomass accumulated.

The relationship of light and plant geometry to self-thinning of an aquatic annual herb, Murdannia keisak (Commelinaceae).
Self-thinning was examined in shaded and unshaded populations of Murdannia keisak (Hask.) Hand.-Mazz. (Commelinaceae). Four mathematical descriptions of self-thinning were compared: (1) the
Plant mass–density relationship along a moisture gradient in north‐west China

Arbuscular mycorrhizal fungi alter plant allometry and biomass-density relationships.
With a high level of AMF, the biomass-density exponent can be predicted from the above-ground allometric model of self-thinning, while this was not the case when AMF were reduced by fungicide.
Plant height–crown radius and canopy coverage–density relationships determine above-ground biomass–density relationship in stressful environments
A novel geometric model with assumptions of allometric growth at the individual level and open canopy at the stand level is developed and it is proposed that plant height–crown radius and canopy coverage–density relationships determine the above-ground M–N relationship in stressful environments.
