Peter L. Steponkus; F. O. Lanphear PLANT PHYSIOLOGY 1968. doi:10.1104/pp.43.2.151
Other claims from this paper (8)
- Intervention effect Light greatly increased cold hardiness.
- Observation Cold acclimation could occur without light.
- Intervention effect Photoperiods of 8 to 24 hours equally promoted maximum hardiness.
- Intervention effect Low light intensities stimulated maximum hardiness.
- Intervention effect Short photoperiods stimulated maximum hardiness.
- Association Longer photoperiods proportionally increased hardiness only in prestarved stems.
- Intervention effect High concentrations of photosynthetic inhibitors decreased hardiness.
- Observation Hardiness under these treatments did not fall to the dark control level.
