Chlorophyll Fluorescence Measurements in Arabidopsis Wild-type and Photosystem II Mutant Leaves

Bio-Protocol, 2015
Chlorophyll fluorescence measurement is a widely used technique to determine photosynthetic performance. Light energy absorbed by a chlorophyll molecule can be dissipated by driving photochemical energy conversion, as heat in non-photochemical quenching ...

Subsurface chlorophyll maxima reduce the performance of non-photochemical quenching corrections in the Southern Ocean

Frontiers in Marine Science
Non-photochemical quenching (NPQ) within phytoplankton cells often causes the daytime suppression of chlorophyll fluorescence in the Southern Ocean. This is problematic and requires accurate correction when chlorophyll fluorescence is used as a proxy for

The effect of physiological age of potato plants on chosen chlorophyll fluorescence parameters

Plant, Soil and Environment, 2015
Potato (Solanum tuberosum L.) crop is the world's number one non-grain food commodity and the fourth main food crop in the world after maize, rice and wheat. It is a typical plant mainly of temperate climate.
