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 ...
متن کاملCorrelation Analysis between Indices of Tree Leaf Spectral Reflectance and Chlorophyll Content
This study was conducted to investigate variations of leaf chlorophyll content and surface spectral reflectance of different tree species (Daphniphyllum glaucescens、Michelia formosana、Illicium dunnianum and Machilus kusanoi) across contrasting terrain in the Nanjenshan Reserve of Kenting National Park, Southern Taiwan. The results showed that there were significant differences (P < 0.01) among ...
متن کاملRelationships between leaf chlorophyll content and spectral reflectance and algorithms for non-destructive chlorophyll assessment in higher plant leaves.
Leaf chlorophyll content provides valuable information about physiological status of plants. Reflectance measurement makes it possible to quickly and non-destructively assess, in situ, the chlorophyll content in leaves. Our objective was to investigate the spectral behavior of the relationship between reflectance and chlorophyll content and to develop a technique for non-destructive chlorophyll...
متن کاملReflectance Variation within the In-Chlorophyll Centre Waveband for Robust Retrieval of Leaf Chlorophyll Content
The in-chlorophyll centre waveband (ICCW) (640-680 nm) is the specific chlorophyll (Chl) absorption band, but the reflectance in this band has not been used as an optimal index for non-destructive determination of plant Chl content in recent decades. This study develops a new spectral index based solely on the ICCW for robust retrieval of leaf Chl content for the first time. A glasshouse experi...
متن کاملSelection of Optimum Reflectance Ratios for Estimating Leaf Nitrogen and Chlorophyll Concentrations of Field-Grown Cotton
often result in immoderate growth, increased input costs, and potential adverse environmental impacts, esLeaf N and chlorophyll (Chl) concentrations of cotton (Gossypium pecially water quality (Jaynes et al., 2001). Therefore, hirsutum L.) are important indicators of plant N status. Laboratory one of the goals of farm managers is to accurately detect determinations of plant tissue N are time co...
