Chlorophyll a rf value
WebIn thin-layer chromatography, the retention factor (Rf) is used to compare and help identify compounds. The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin). WebAfter morphological traits measurement, all siliques of each layer were then selected to acquire chlorophyll a fluorescence at green-mature siliquing stage (45 days after first flowering). The OJIP transients and JIP-test parameters of siliques were measured using a portable fluorescence detector (Handy-PEA, Hansatech Instruments ltd., Pentney, U.K.) …
