leaf area index , LAI (skrót)

The interception depends on the leaf area index and what kind of leaves they are.

Leaf area index of boreal forests: theory, techniques, and measurements.

Plant canopy gap size analysis theory for improving optical measurements of leaf area index.

For further explanation see leaf area index.

The use of hemispherical photographs for determining the leaf area index of young crops.

Defining leaf area index for non-flat leaves.

Leaf Area Index is the total leaf surface area per unit ground area.

So, if their arguments (they term them a "postulate") are correct, we should expect plants to expand what they term the "leaf area index."

The amount of biomass in leafs determines the leaf area index, which is important in calculating the gross photosynthetic production.

Typically, the Leaf Area Index (LAI) is above two to three in this phase.

Land surface characteristics such as surface albedo, leaf area index, vegetation index and surface temperature are derived from satellite imagery.

Leaf Area Index (LAI) is a dimensionless quantity that characterizes plant canopies.

The rate of this reaction often depends on sunlight intensity, leaf area index, leaf angle and amount of chloroplasts per leaf surface unit.

Rapid estimation of leaf area index in forests using the LI-COR LAI-2000.

Typical examples include the Leaf Area Index, biomass, chlorophyll concentration in leaves, plant productivity, fractional vegetation cover, accumulated rainfall, etc.

Leaf area index (LAI), leaf area per unit ground area, is a key measure used to understand and compare plant canopies.

Calculation of leaf area index and other canopy indices from gap fraction: a manual for the LAICALC software.

The growth of the crop is linearly dependent on leaf area index, which in its turn is linearly dependent on crop biomass.

Canopy indices, such as leaf area index, are based on calculation of gap fraction, the proportion of visible (non-obscured) sky as a function of sky direction.

With the obtaining of FPAR can be calculated LT (total leaf area index) and N (canopy greenness fraction).

These can be quite elaborate in the case of certain maize varieties, but tend to use a trapezoidal or leaf area index (LAI) curve for common crop or vegetation canopies.

The abundance of sunflecks varies greatly both within and amongst forest types, generally the frequency and intensity of sunflecks decreases as tree height and the leaf area index increase.

Image annotations: The featured plot shows Leaf Area Index (LAI), a measure of global vegetative matter, from a NetCDF dataset.

Analysis results for an individual plant are generalised to the standard surface, e.g. the Leaf Area Index is the projected surface area of all crop leaves above a unit area of ground.

This geometry can be measured precisely and used to calculate solar radiation transmitted through (or intercepted by) plant canopies, as well as to estimate aspects of canopy structure such as leaf area index.
