Leaf areais important in determining plant growth rate (seeREGULATORS OF GROWTH | Growth Analysis, Individual Plants). For crops, a new term is introduced calledleaf areaindex (LAI). Theleaf area indexis the ratio of the leaf area of all the plants to the ground area they occupy. Hence,...
For each plot, three plants were randomly selected to measure the total green leaf area with the non-destructive portable leaf area meter (Laser Area Meter CI-203; CID Inc.). And the average leaf area of selected plants represented the single plant leaf area in each experiment plot. The LA...

The leaf area in a picture can be calculated by measuring the actual area every pixel accounts for in the digital image and the number of pixels that the leaf image covers.Accordingly,we provide a method to obtain the plant leaf image by digital camera and to measure the leaf area precisely...
Darker nongreen components in C and E fit pixel threshold and color ratio criteria, but were below the minimum component size, and so were not included in leaf area or canopy cover calculations. Minimum component size analysis was not used in F-L. 展开 ...
Leaf area index (LAI) is a key indicator for the assessment of the canopy’s processes such as net primary production and evapotranspiration. For this reason, the LAI is often used as a key input parameter in ecosystem services’ modeling, which is emerg
Leaf area index (LAI) is the ratio of the total one-sided leaf area to the ground area, whereas lateral growth (LG) is the measure of canopy expansion. They are indicators for light capture, plant growth, and yield. Although LAI and LG can be directly me
In order to evaluate the performance of the software, leaves with symptoms of mite injury were collected from six different plant species (squash, cucumber, green bean, vigna, dahlia and rose). Symptom area of each leaf was assessed manually and by the software. It was observed that the ...
The leaf area index (LAI), defined as the photosynthetically active area per unit horizontal surface area, is related to crop development, water use, nutrient uptake, and yield [11,12,13] and used to monitor changes in canopy structure and assess environmental adaptability [14,15]. The LAI ...
This study discusses the relationship between the spectral behavior of vegetation and vegetation indexes, using Landsat satellite images to estimate the Leaf Area Index (LAI) in a protected area in the state of São Paulo, Brazil. We calculated the Normalized Difference Vegetation Index (NDVI) for...
