Genome-Wide Association Study of Leaf Chlorophyll Content Using High-Density SNP Array in Peanuts (Arachis hypogaea L.)

Agronomy, 2022
The content of chlorophyll, a fundamental component required for photosynthesis in plants, has been widely studied across crop species. In this study, we aimed to evaluate the genetic diversity of 453 peanut accessions.

Designing and Developing a Machine Vision System to Predict the Chlorophyll and Carotenoid Content of Plant Leaves [PDF]

Journal of Agricultural Machinery, 2019
Introduction Leaf color is usually used as a guide for assessments of nutrient status and plant health. Most of the existing methods that examined relationships between chlorophyll status and carotenoid of leaf color were developed for particular species.

The Change of Chlorophyll Content and Chlorophyll Efficiency in Epipremnum aureum by Water and pH

European Journal of Botany, 2022
Epipremnum aureum (pothos) is an herbaceous species and is originated to tropical or subtropical South East Asia and Solomon islands. This study investigated the effect of excessive moisture on chlorophyll content and photosynthesis efficiency on E. aureum.

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.

The global distribution of leaf chlorophyll content [PDF]

Remote Sensing of Environment, 2020
Leaf chlorophyll is central to the exchange of carbon, water and energy between the biosphere and the atmosphere, and to the functioning of terrestrial ecosystems. This paper presents the first spatially-continuous view of terrestrial leaf chlorophyll content (ChlLeaf) at the global scale.

Evaluation and calibration of noninvasive leaf chlorophyll meters for wheat

Journal of Agrometeorology, 2015
Nondestructive and fast chlorophyll assessment can be made with portable chlorophyll meters. The meters measure the transmittance of red and near infrared radiation through the leaf and estimates the chlorophyll in non-dimensional index values by ...
