Evaluation of the Reliability of the CCM-300 Chlorophyll Content Meter in Measuring Chlorophyll Content for Various Plant Functional Types [PDF]

open access: yesSensors
Chlorophyll fluorescence is a well-established method to estimate chlorophyll content in leaves. A popular fluorescence-based meter, the Opti-Sciences CCM-300 Chlorophyll Content Meter (CCM-300), utilizes the fluorescence ratio F735/F700 and equations ...

Evaluation of the Methods for Estimating Leaf Chlorophyll Content with SPAD Chlorophyll Meters

open access: yesRemote 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.

Guidelines for quantifying leaf chlorophyll content via non‐destructive spectrometry [PDF]

open access: yesApplications in Plant Sciences
Premise Leaf chlorophyll is a fundamental bioindicator used in several fields; however, we lack clear guidelines for optimizing sampling efforts and producing comparable studies. Methods We estimated the leaf chlorophyll content of 10 plant species using

A nondestructive method to estimate the chlorophyll content of Arabidopsis seedlings [PDF]

open access: yesPlant Methods, 2017
Background Chlorophyll content decreases in plants under stress conditions, therefore it is used commonly as an indicator of plant health. Arabidopsis thaliana offers a convenient and fast way to test physiological phenotypes of mutations and treatments.
