Quick Estimation of Apple (Red Delicious and Golden Delicious) Leaf Area and Chlorophyll Content
ABSTRACT- The evaluation of leaf area and leaf nutritional value is important for crop growth modeling and estimations of its performance. The purpose of this study was to use image processing techniques to develop an economical method to ease the assessment of nutrient status and leaf area (LA) of plants and to compare the outcomes of this method with linear models. Leaf area and leaf chloroph...

متن کاملMultivariate statistical methods for estimating grassland leaf area index and chlorophyll content using hyperspectral measurements
Grassland habitat covers about one-quarter of the Earth’s land surface, providing significant contribution to the world’s total agricultural production, plant biodiversity, and carbon sequestration. The advent of hyperspectral remote sensing and the future launch of planned spaceborne hyperspectral missions will open up new possibilities over conventional multispectral RS to better quantify gra...
متن کاملTemporal disparity in leaf chlorophyll content and leaf area index across a growing season in a temperate deciduous forest
Spatial and temporal variations in canopy structure and leaf biochemistry have considerable influence on fluxes of CO2, water and energy and nutrient cycling in vegetation. Two vegetation indices (VI), NDVI and Macc01, were used to model the spatio-temporal variability of broadleaf chlorophyll content and leaf area index (LAI) across a growing season. Ground data including LAI, hyperspectral le...
