Other claims from this paper (12)
- Intervention effect Drought stress increased the water loss rate of tea.
- Intervention effect Drought stress decreased the relative water content of tea leaves.
- Intervention effect Drought stress decreased total phenolic contents, ascorbate and glutathione of tea leaves.
- Observation Leaf antioxidant enzymes of tea showed differential activities.
- Intervention effect Progressive drought stress increased ROS and lipid peroxidation in tea.
- Intervention effect Progressive drought stress decreased POX activities in tea.
- Intervention effect Drought stress decreased leaf Zn, Ca and Na contents in tea.
- Intervention effect Drought stress decreased leaf Fe, Mg and K contents in tea.
- Intervention effect Tea plants exposed to heavy metals showed reduced growth and antioxidative responses.
- Observation Tea plants recover on rehydration after drought, so drought-induced biochemical damage is not permanent.
- Intervention effect Foliar spray of K, Ca and Zn significantly improved antioxidant potential during post-drought recovery in tea.
- Recommendation Drought tolerance and post-drought recovery of tea can be improved by applying K, Ca, Zn and B.
