Plants' form, size, volume, weight, and other characteristics change permanently and irreversibly as they grow. On this foundation, plant growth metrics are analyzed.
As a result, some of the factors that can be used to evaluate plant growth include the number of cells on a leaf's cross-section, the thickness of a leaf's epidermis (upper), water uptake intensity, rate of eructation, rate of perspiration, rate of relative growth (RGR), leaf-to-body-weight ratio (LWR), ratio of leaf area (LAR), leaf surface area (SLA), duration of the lead area (LAD), growth rate in absolute terms (AGR), weight of individual leaves (SLW), crop development rate (CGR), ratio of net assimilation (NAR).
