Dear PhotosynQ User,
Welcome to the PhotosynQ community newsletter!
Today, we have the following study by Zhu et al. (2021) as our featured project. This project corresponds well with PhotosynQ's new SPAD only protocol released recently which can measure leaf relative chlorophyll in 2-3 seconds.
We hope you enjoy reading our selected study and testing our new staff-selected protocol.
Please stay safe and healthy! Best, PhotosynQ Team

This study measured leaf chlorophyll concentration (LCC) using MultispeQ V2.0. Authors highlighted the MultispeQ as a device that can record LCC as a highly reproducible measurement. Authors converted LCC into LCC-actual (mg/kg) based on Zhu et al. (2020). Zhu et al. (2021) used y=9.6324e^0.029x to calculate LCC in maize using the empirical relationship developed in Zhu et al. (2020).

This study highlights the easy conversion from MultispeQ unitless LCC to mg/kg LCC through use of a crop specific pilot study.
