Other claims from this paper (13)
- Intervention effect Biomass accumulation and relative growth rate were similar in coffee seedlings produced in full sun and in shade.
- Intervention effect Full-sun coffee seedlings had less biomass allocation to shoots than shade seedlings.
- Intervention effect Full-sun coffee seedlings had a lower leaf mass ratio than shade seedlings.
- Intervention effect Full-sun coffee seedlings had a lower leaf area ratio than shade seedlings.
- Intervention effect Full-sun coffee seedlings had a greater net assimilation rate than shade seedlings.
- Intervention effect Full-sun coffee seedlings had a greater net photosynthetic rate, associated with the greater net assimilation rate.
- Intervention effect Total chlorophyll concentrations and the chlorophyll a/b ratio did not differ between full-sun and shade seedlings.
- Intervention effect Full-sun coffee seedlings showed no indications of photoinhibition or photooxidative damage.
- Intervention effect Coffee seedlings transferred from shade to full sun were not capable of utilising the extra incident light to fix CO2.
- Intervention effect Seedlings moved from shade to full sun showed a remarkable nocturnal retention of zeaxanthin.
- Intervention effect Seedlings moved from shade to full sun showed a significantly increased deepoxidation state of the xanthophyll cycle, even at predawn.
- Intervention effect Seedlings moved from shade to full sun had lower antioxidant enzyme activity than T1 and T2 plants.
- Intervention effect Despite acclimation capacity, seedlings moved to full sun showed chronic photoinhibition and considerable photooxidative damage throughout the seven days after transfer.
