Title
Physiological parameters in sugarcane cultivars submitted to water deficit
José Perez da Graça; Fabiana Aparecida Rodrigues; José Renato Bouças Farias; et al. Brazilian Journal of Plant Physiology 2010. doi:10.1590/s1677-04202010000300006
Other claims from this paper (7)
- Intervention effect Water deficit significantly decreased photosynthetic rate in all tested sugarcane cultivars.
- Intervention effect Water deficit significantly decreased stomatal conductance in all tested sugarcane cultivars.
- Observation Under control conditions, SP83-2847 and CTC15 had higher photosynthetic rates than SP86-155.
- Observation CTC15 had the highest relative water content during the dry period.
- Mechanism The authors suggest that declining relative water content stimulated adjustment of photosynthetic capacity in SP83-2847.
- Observation The tolerant SP83-2847 and CTC15 cultivars had better photosynthetic performance than SP86-155.
- Recommendation The authors suggest these physiological parameters can distinguish drought tolerant and sensitive sugarcane genotypes.
