The allocation of biomass to different plant organs depends on species, ontogeny and on the environment experienced by the plant. In this paper we first ...

That is, plants will allocate relatively more biomass to roots if the limiting factor for growth is below ground (e.g. nutrients, water), ...

Biomass allocation is the end result of a number of processes which take place in the plant. It starts with the way how sugars are allocated over the different organs after having been fixed by the leaves in the process of photosynthesis ( sugar allocation ).

Biomass allocation varied among functional types as a result of phenological (deciduous vs evergreen broad-leaved species) and broad phylogenetical (angiosperms vs gymnosperms) differences. Furthermore, the direction of biomass allocation responses between tolerant and intolerant species was often opposite to that predicted by the optimal ...

We quantified the biomass allocation patterns to leaves, stems and roots in vegetative plants, and how this is influenced by the growth ...

As explained above, biomass allocation is driven by the sink strengths of all expanding organs. The sink value of an organ depends on its physiological age and on its type o ( o = b, p, i, c, f for leaf blade, petiole, internode, secondary growth rings on stems, and fruits or flowers, respectively) and its chronological age j.

The growth rates and patterns of above- ground biomass allocation were determined for saplings of nine species of a wet tropical forest in. Costa Rica. Relative ...

Total plant biomass was calculated as the sum of below-ground, stem, leaf and reproductive biomass, and mass fractions were calculated as the ...

01.12.1999 · We examined biomass allocation patterns throughout the entire vegetative growth phase for three species of annual plants along three separate gradients of resource availability to determine whether observed patterns of allocational plasticity are consistent with optimal partitioning theory.

Biomass allocation is a concept in plant biology which indicates the relative proportion of plant biomass present in the different organs of a plant. It can also be used for whole plant communities.

01.12.2020 · Biomass allocation has great impacts on plant competition, ecosystem succession, health and productivity (Agathokleous et al., 2019). It is also an important ecological parameter in dynamic global vegetation models (Mokany et al., 2006), as it is used to estimate the belowground plant biomass from aboveground biomass data (Litton et al., 2007).

Biomass allocation is often assessed as the fraction of each organ's biomass to total plant biomass, which potentially reflects plant strategies ...

These files are organized into four general sections: the taxa and literature citation, plant characteristics of age and height (measured and log10 transformed), biomass allocation (measured and log10 transformed), and growth (measured and log10 transformed).

Nevertheless, some general patterns in biomass allocation can be observed . In a one-way ANOVA of biomass allocation data drawn from field studies, vegetation type accounts for 24%, 66% and 67% of the total variation across observations in LMF, SMF and RMF, respectively.

The pattern of biomass allocation between leaves and shoots also indicates how a species optimizes resource use and determines crown architecture (Souza et ...

13.04.2021 · Biomass allocation between belowground biomass and aboveground biomass differed among species in our study, in line with previous findings (Ma et al., 2008; Kang et al., 2013; Gong et al., 2015; Zhang et al., 2019). Mokany et al. (2006) suggested that the root/shoot (R/S) ratio in grasslands tends to decrease with increasing MAP.

We quantified the biomass allocation patterns to leaves, stems and roots in vegetative plants, and how this is influenced by the growth environment, plant size, evolutionary history and competition. Dose-response curves of allocation were constructed by means of a …

Biomass allocation patterns for adult trees are generally known only from data in forest stands and thus are confounded with a possible density effect (see Section VIII). On average, there is no difference in allocation to roots between conifers and angiosperm trees.

05.11.2020 · Biomass allocation is a key factor in understanding how ecosystems respond to changing environmental conditions. The role of soil chemistry in the above- and belowground plant biomass allocation in restoring grassland is still incompletely characterized.
