'Leaf Area Index' refers to a measure calculated by summing the crown projections of trees with known surface area of assimilating organs, reflecting changes in them due to radiation damage of needles and leaves. AI generated definition based on: Journal of Environmental Radioactivity, 2022 ...
28.5.2Second problem: calculation of leaf area index Theleaf areaindex, L, is defined as the area of leaves above unit area of ground taking only one side of each leaf into account. It can be expressed in such units as the following: ...
Leaf area index (LAI) is a fundamental indicator of crop growth status, timely and non-destructive estimation of LAI is of significant importance for precision agriculture. In this study, a multi-rotor UAV platform equipped with CMOS image sensors was used to capture maize canopy information, sim...
the leaf area index needs to be included in the calculation of photosynthetic nitrogen use-efficiency. These effects are scale-emergent properties, meaning that evaporation or leaf area index are not prominent properties for leaf-level processes, but they are key at the ecosystem scale. At this ...
Consequently, the leaf area index needs to be included in the calculation of photosynthetic nitrogen use-efficiency. These effects are scale-emergent properties, meaning that evaporation or leaf area index are not prominent properties for leaf-level processes, but they are key at the ecosystem scale...
Thus, these instruments were primarily useful for relative within-site plant area index monitoring. Calculation of some parameters required destructive sampling, a relatively slow and labor-intensive activity that limits spatial and temporal applicability. Validation/monitoring campaigns therefore should be ...
The objective of this study was to evaluate the efficiency of the leaf disc method for estimating the leaf area index (LAI) of soybean plants in comparison with the digital photo method. A split-plot experimental design was used with three replications. The LAIs calculated by the leaf disc ...

Calculation of Growth Duration and Maximum Growth Rate. A is the area of a single leaf (cm2), A0 is initial leaf area (0.05 cm2), Af is final leaf area, D is decay in specific leaf expansion rate (day-1) and DAA is the days after appearance of the leaf (day). ...
