Non-destructive methods for estimating biomass in ornamental plants are crucial for maintaining plant health and appearance while gathering important data. These methods typically rely on allometric relationships between easily measurable plant dimensions and biomass. A common approach involves measuring parameters such as plant height, stem diameter, crown width, and leaf area index, then using these measurements in species-specific or generalized allometric equations to estimate total biomass. Advanced techniques may incorporate digital imaging and analysis, where photographs or 3D scans of plants are processed to estimate volume and density, which are then correlated with biomass. Another non-invasive method uses chlorophyll fluorescence measurements to assess plant physiological status and indirectly estimate biomass. For smaller ornamental plants, weighing the entire potted plant and subtracting the weight of the pot and growing medium can provide a good estimate of above-ground biomass. Remote sensing techniques, including LiDAR and multispectral imaging, are also being adapted for ornamental plant biomass estimation, especially in larger landscape settings. These non-destructive methods, while sometimes less accurate than direct measurements, offer valuable ways to monitor plant growth and estimate biomass without compromising the aesthetic or structural integrity of ornamental plants.
