Other claims from this paper (11)
- Observation Dendrobium could adapt to higher light intensity in winter than in the growing period.
- Observation The light saturation point of D.primulinum was as high as 1 000 μmol·m-2·s-1.
- Observation The light saturation point of D.chrysotoxum was as high as 1 000 μmol·m-2·s-1.
- Observation The light saturation point of D.nobile was 300 μmol·m-2·s-1, lower than in the other two species.
- Observation The maximum net photosynthetic rate of D.chrysotoxum was 3.92 μmol·m-2·s-1.
- Observation The maximum net photosynthetic rate of D.primulinum was negative.
- Intervention effect After exposure to high light of 2 000 μmol·m-2·s-1, light saturation points of all species decreased.
- Mechanism High-light exposure indicated that photoinhibition had existed in the Dendrobium species.
- Association Photosynthetic rate was positively correlated with Cond in D.nobile and D.chrysotoxum.
- Association Photosynthetic rate was negatively correlated with Ci in all three Dendrobium species.
- Mechanism The decrease in photosynthesis is attributed to non-stomatal factors.
