WebFeb 15, 2024 · The proportion of plant biomass allocated to leaves, stems and roots (leaf mass ratio, LMR; stem mass ratio, SMR; root mass ratio, RMR) is contingent on the growth environment, species, the individual developmental stages of plants and competition (Yan et al. 2024a). Biomass allocation strategies are an important feature of plant responses … WebA complete treatment of biomass allocation during on-togeny is complex (e.g., Harper and Ogden 1970; Howarth and Williams 1972; Day 1987; West et al. 1997).

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. 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 19, 2024 · Age is the most vital factor influencing the magnitude and distribution of biomass in plants. In this study, the total individual tree, leaf, stem, branch and root biomass increased promptly from the 9th to the 22nd year, where a linear positive correlation could be extracted for this species between forest age and total tree biomass.
WebJun 14, 2024 · New biomass produced by photosynthesis is transported to the leaves, stems, roots, and reproductive organs. When new biomass is proportionally allocated to these sinks, it also ensures proportional distribution of new carbon (Reich et al., 2014).
