e0“In the absence of water deficits, rates of shoot initiation and extension are determined by air temperature and saturation vapour pressure deficit, with the former having positive and the latter having negative relationships with the above rates.”

Other claims from this paper (9)
- Observation Tea photosynthetic apparatus and processes are adapted to shade.
- 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 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.
