Cold-induced sudden reversible lowering of in vivo chlorophyll fluorescence after saturating light pulses
1989
Larcher, W. | Neuner, G.
In chilling-sensitive plants (Glycine max, Saintpaulia ionantha, Saccharum officinarum) a sudden reversible drop in chlorophyll fluorescence occurs during photosynthetic induction immediately following saturating light pulses at low temperatures in the range 4 to 8 degrees C. A comparison of two soybean cultivars of different chilling sensitivities revealed that this phenomenon, termed low-wave, indicates specific thresholds of low temperature stress. Its occurrence under controlled chilling can be regarded as a quantitative marked for screening chilling susceptibility in angiosperms.
