Other claims from this paper (9)
- Observation Tea maximum light saturated photosynthetic rates are below the C3 plant average.
- Observation High light intensities cause photoinhibition in tea.
- Mechanism These photosynthetic processes restrict tea source capacity.
- Mechanism Harvesting shoots before maximum biomass to maintain quality makes tea yield sink limited.
- Association Air temperature is positively related to tea shoot initiation and extension without water deficits.
- Association Saturation vapour pressure deficit is negatively related to tea shoot initiation and extension without water deficits.
- Association During dry periods beyond a soil water deficit threshold, tea shoot initiation and extension decline with decreasing shoot water potential.
- Intervention effect Tea yields respond significantly to irrigation during dry periods.
- Recommendation The authors propose irrigation to increase tea productivity during dry periods.
