Intervention effect High temperature reduced Fv/Fm to 52% during 15 days of treatment.
Intervention effect High temperature reduced Fv/F0 to 85%.
Intervention effect High temperature reduced ΦPSII to 65%.
Intervention effect High temperature reduced rETR to 65%.
Intervention effect High temperature increased F0 to 226%.
Intervention effect Low temperature decreased Fv/Fm by 16%.
Intervention effect Low temperature decreased Fv/F0 by 50%.
Intervention effect Low temperature decreased rETR by 16%.
Intervention effect High temperature decreased nocturnal acidification by approximately 34-50%.
Intervention effect Low temperature increased nocturnal acidification by 30-36%.
Intervention effect Continuous high temperature affected diurnal malic acid consumption.
Intervention effect Continuous low temperature affected diurnal malic acid consumption.
Association Changes in diurnal malic acid consumption were associated with significant inhibition of relative growth rate.
Observation The specific photosynthetic structure area component was most affected.
Mechanism The authors concluded that photosynthetic impairment inhibited growth in young plantlets under extreme temperature.
