Models for leaf area estimation in dwarf pigeon pea by leaf dimensions

Leaf area estimation by a simple and non-destructive method

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

Leaf Area Index in Earth System Models

The amount of leaves in a plant canopy (measured as leaf area index, LAI) modulates key land–atmosphere interactions, including the exchange of energy, moisture, carbon dioxide (CO 2), and other trace gases, and is therefore an essential variable in predicting terrestrial carbon, water, and energy fluxes. The latest generation of Earth system 5 models (ESMs) simulate LAI, as well as provide pro...

Estimation of Leaf Area Index in Dwarf Mountain Pine (pinus Mugo Turra) Using Hyperspectral Data

The natural environment of the Tatras is one of the most diverse in Europe in terms of species richness and ecological value. This mountain range is well preserved and constitutes an important part of Europe’s nature resources. Dwarf pine (Pinus mugo Turra) is the main component of the Tatras subalpine belt covering altitude between 1550 and 1800 m a.s.l. It is a very dynamic species, which exp...
