Calibration of the Minolta SPAD-502 leaf chlorophyll meter

Photosynthesis Research, 1995
Use of leaf meters to provide an instantaneous assessment of leaf chlorophyll has become common, but calibration of meter output into direct units of leaf chlorophyll concentration has been difficult and an understanding of the relationship between these two parameters has remained elusive. We examined the correlation of soybean (Glycine max) and maize

Nondestructive and Rapid Estimation of Leaf Chlorophyll and Nitrogen Status of Peace Lily Using a Chlorophyll Meter

Journal of Plant Nutrition, 2004
Abstract Timely and nondestructive detection of leaf nitrogen (N) status could greatly improve nutrient management practices for greenhouse ornamental production. This study evaluated the feasibility of using a SPAD-502 chlorophyll meter for estimating leaf chlorophyll and nitrogen contents of the peace lily (Spathiphyllum Schott).

Evaluation of a SPAD-502 Plus Chlorophyll Meter to Estimate Chlorophyll Content in Leaves with Interveinal Chlorosis

Russian Journal of Plant Physiology, 2020
The portable chlorophyll (Chl) meter SPAD-502 Plus (Konica Minolta Optics, Japan) is one of the most commonly used diagnostic tools for rapid and nondestructive estimation of Chl content in leaves of crops and tree species. The aim of this work was to evaluate the performance of a SPAD-502 Plus to estimate the content of Chl a, Chl b, and Chl (a + b ...

Anthocyanin contribution to chlorophyll meter readings and its correction

Photosynthesis Research, 2013
Leaf chlorophyll content is an important physiological parameter which can serve as an indicator of nutritional status, plant stress or senescence. Signals proportional to the chlorophyll content can be measured non-destructively with instruments detecting leaf transmittance (e.g., SPAD-502) or reflectance (e.g., showing normalized differential ...
