23 lip 2024 · To measure a plant’s growth rate, use a ruler or measuring tape to measure from the base of the plant to its highest point. If your plant is in a pot, start your measurement at the base of the pot. Write the measurement down, then repeat 2-3 days later.

Plant growth rate can be measured as the relative increase in leaf area over time, by substituting total plant leaf area for total biomass in the conventional RGR equation. RGR A = (ln LA 2 −ln LA 1) / ( t 2 − t 1) (6.14)
7 sie 2021 · We propose a general framework to distinguish between the different facets of growth, and the corresponding physiological processes, environmental drivers and mathematical formalisms. Based on...
10 lip 2021 · In this paper, we review these various facets of plant growth at different levels from cells to organs, plants, and ecosystems (the ‘what’). We emphasize that each facet can be defined using corresponding reference metrics, formalisms and frames of analysis.
18 wrz 2021 · Models of population dynamics can be constructed in which demographic rates (growth, survival, fecundity) are directly modelled as a function of plant size/stage and appropriate abiotic and community composition covariates.
10 mar 2015 · The objective of this paper is to explore how relative growth rates of individual plants as well as of plant populations can be efficiently analysed and modelled using a system of simultaneous functions of relative growth and allometric relationships developed in different research schools.
25 gru 2001 · In this paper, a theoretical framework for the analysis of growth is described. Growth is equated with change in volume (V) and the growth rate is given by the equation; d V /d t = (d m /d t) (1/ ρ) − (d ρ /d t) (m / ρ2) where m is the mass and ρ the density. The volume is inclusive of internal air spaces. 2.
