Other claims from this paper (10)
- Intervention effect The L75 treatment significantly reduced net photosynthetic rate, stomatal conductance and transpiration rate compared with the control.
- Intervention effect The L75 treatment significantly reduced total aboveground and root dry weight, maximum net photosynthetic rate and maximum rate of electron transport compared with the control.
- Intervention effect Plant height and leaf area were not reduced by the L75 treatment compared with the control.
- Intervention effect Lower light intensities (L50 and L20) and longer shade duration led to greater reduction in growth, leaf thickness and photosynthetic potential.
- Intervention effect The L75 treatment caused no significant reduction in the activities of Rubisco and PEPC.
- Intervention effect Lower light intensities (L50 and L20) and longer shade duration significantly reduced enzyme activity.
- Association Tung trees have greater photosynthetic activity under high light intensity.
- Intervention effect Shading, even at 20 percent, reduced photosynthetic efficiency and growth, especially over the longer term.
- Recommendation Tung trees should be grown under full sun with a daily light integral of about 46 mol m-2 d-1 to prevent growth reduction.
- Recommendation Mutual shading in tung tree canopies should be avoided by proper spacing and pruning.
