Cowpea Parent Screening - Cold temperatures


Donghee Hoh and Anna Cowie

The purpose of this project is to determine several parameters of NPQ and PSII for different cowpea genotypes in order to select a cross for a future cold stress experiment to determine the QTL of cold stress.



This protocol measures a series of factors that allow us to estimate: stomatal conductance (via changes in humidity and leaf temperature);
ATP synthase conductivity, pmf parameters through DIRK(ECS) The rate of turnover of the cytochrome b6f complex through DIRKP(700) Chlorophyll fluorescence parameters Phi2, NPQ(t), PhiNPQ, PhiNO, qL(t) ...
