| Experiment Description: | An experiment was conducted to test for the photosynthetic acclimation timeframe in relation to temperature. Adaptation and acclimation of photosynthetic properties were also tested. | ||

Two Brassica oleracea genotypes originating from a warm climate and cool climate, respectively, were grown under two temperature regimes (warm and cool) – 5 plants per genotype by temperature treatment.
After development, half the plants of each genotype by growth temperature treatment were switched. Gas exchange measurements were made prior to the switch, then 1, 8 and 15 days after the switch. LMA and biomass were determined 15 days after the switch. |
Data are available on request, although analysis and accompanying modelling is ongoing.

Leaf age could be a factor but leaves of both treatment and control plants were the same age for at each measurement timestep.
The photosynthetic acclimation response was more rapid than expected. |
