Maximum photosynthetic efficiency: A problem to be resolved [PDF]

Biotechnology and Bioengineering, 1983
AbstractThe great disarray in the measurements of the maximum efficiency of conservation of light energy in photosynthesis is an outstanding problem in the development of photosynthetic biotechnology. The short‐term measurements of the efficiency based on O2 release by suspensions of cells or chloroplasts have given minimum quantum demands between 4 ...

Salt response of photosynthetic electron transport system in wheat cultivars with contrasting tolerance

Plant, Soil and Environment, 2016
Soil salinity significantly decreases the photosynthetic efficiency and plant growth in wheat (Triticum aestivum L.). However, sensitivity of the photosynthetic electron transport system of wheat in relation with salt stress is unclear.

Relative tolerance of photosystem II in spike, leaf, and stem of bread and durum wheat under desiccation

Photosynthetica, 2019
In dryland regions, soil moisture stress often leads to desiccation and causes injury to photosynthetic machinery. Recently, chlorophyll fluorescence (ChlF)-based assessment of photosynthetic efficiency under drought stress is gaining attention due to ...
