Evaluation of the Methods for Estimating Leaf Chlorophyll Content with SPAD Chlorophyll Meters
Remote Sensing, 2022 Leaf chlorophyll content (LCC) is an indicator of leaf photosynthetic capacity. It is crucial for improving the understanding of plant physiological status. SPAD meters are routinely used to provide an instantaneous estimation of in situ LCC. However, the calibration of meter readings into absolute measures of LCC is difficult, and a generic approach ...

Estimation of Chlorophyll Using SPAD meter
International Journal of Environment and Climate Change, 2023 A chlorophyll meter measures the greenness of leaves and can indicate the chlorophyll content and N status. Therefore, by using a chlorophyll meter, proxy information related to the leaf N content could be obtained and this would avoid the need of laborious laboratory analysis.

Inherent Limitations of Nondestructive Chlorophyll Meters: A Comparison of Two Types of Meters [PDF]
HortScience, 1992 Two types of nondestructive chlorophyll meters were compared with a standard, destructive chlorophyll measurement technique. The nondestructive chlorophyll meters were 1) a custom built, single-wavelength meter, and 2) the recently introduced, dual-wavelength, chlorophyll meter from Minolta (model SPAD-502).

Using a chlorophyll meter to estimate tea leaf chlorophyll and nitrogen contents [PDF]
Journal of soil science and plant nutrition, 2012 A chlorophyll meter can conveniently estimate foliar chlorophyll and nitrogen (N) contents in many species. The objective of this study was to evaluate the utility of a chlorophyll meter to inform nitrogen fertilization rates of tea (Camellia sinensis L.) at different places and times.
