Biomass allocation to leaves stems and roots
WebJun 30, 2007 · An implied assumption of this is that there are trade-offs in allocation between leaf, stem and root functions. 2 . Recently, an alternative approach, allometric biomass partitioning theory (APT), was developed to predict how plants should divide their metabolic production between leaves, stems and roots, based on the constraints of … WebSep 22, 2024 · We found shifting biomass fractions with plant size and age, supporting the optimal partitioning theory. Young plants (<10 years) allocated similar proportions of biomass to leaves, stems and roots, intermediate-aged plants (10–30 years) allocated more biomass to roots, while the oldest plants had 90% biomass in below-ground stems.

WebNov 3, 2015 · In this study, we investigated the biogeographic patterns of biomass allocation in leaves, stems and roots based on a large-scale biomass survey across forest communities in China. WebWe tested the optimal partitioning theory by analysing how fractional biomass allocation to leaves, stems and roots differed between woody species with different tolerances of shade and drought in plants of different age and size (seedlings to mature trees) using a global dataset including 604 species.

WebOct 1, 2015 · Forest biomass is composed of different tree organs including stems, branches, leaves and roots. The growth and turnover rates of each component define the proportional allocation of standing biomass among these organs, and these rates vary with environmental change, including climate change (Poorter and Sack 2012 ). 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). Conceptually this is simple to envisage, but to quantify the flow of sugars is challenging and requires sophisticated machinery. For plants growing under steady state conditions, it is feasible to determine sugar-allocation by …
WebOct 28, 2024 · Next, we collected total plant biomass of leaves, roots, and stems by clipping plants into various tissues and drying the plant for 48 h at 70°C. Next, we measured plant biomass allocation patterns by calculating leaf, root, and stem mass fractions (leaf, root, or stem biomass [mg]/total biomass [mg] × 100). how many users are on the internetWebJul 24, 2012 · The soil texture significantly changed the biomass allocation to leaves and roots, but not to stems.
