Nondestructive method for estimating the leaf area of sapodilla from linear leaf dimensions

Rapid estimation of sunflower leaf area from linear measurements

One Method of Estimating Vegetation Leaf Area Index from ENVISAT-ASAR Data

One method of estimating vegetation Leaf Area Index (LAI) using ENVISAT-ASAR data was presented based on the ground experiment data in Heihe district, northwest China. Firstly, the vegetation species was analyzed and classified in this area and the category covered the cultural vegetation, shrub, grass, desert, needle forests, and broadleaf forests. With support of experiment data and other mat...

Estimating Corn Leaf Chlorophyll Concentration from Leaf and Canopy Reflectance

Farmers must balance the competing goals of supplying contributions of background reflectance, while spectral vegetation indices that combined reflectances of near-infrared adequate N for their crops while minimizing N losses to the environment. To characterize the spatial variability of N and other visible bands (MCARI and NIR/Green) were responsive to both leaf chlorophyll concentrations and ...

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...

A Leaf Lamina Compression Method for Estimating Turgor Pressure

A portable wiltmeter instrument to estimate leaf turgor pressure according to an adaptation of the flattening method was developed. In the instrument, a flexible inflating membrane presses the leaf against a flattening plate having small orifices surrounded by a finely engraved network of obtuse indentations through which air flow is delivered. During a measurement, as the compression builds up...
