Overall, N addition significantly increased biomass of the whole plant and of leaves, stems, shoots and … 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.

WebAbstract: Summary 1.Optimal partitioning theory (OPT) suggests that plants should allocate biomass to the organ that acquires the most limiting resource. 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 … 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).
WebAbstract: A central goal of comparative life‐history theory is to derive the general rules governing growth, metabolic allocation, and biomass partitioning. Here, we use allometric theory to predict the relationships among annual leaf, stem, and root growth rates (GL, GS, and GR, respectively) across a broad spectrum of seed plant species. Our model … WebNov 5, 2024 · Allometry rather than abiotic drivers explains biomass allocation among leaves, stems and roots of Artemisia across a large environmental gradient in China …
WebJul 24, 2012 · The soil texture significantly changed the biomass allocation to leaves and roots, but not to stems.

WebNov 1, 2024 · Our results show that biomass allocation to leaves, stems and roots is determined by two independent trade-offs that allow plants to respond to soil and light gradients describing patterns that do not always follow the predictions of OPT. east greenwich golf course tee timesWebJun 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).
