Other claims from this paper (15)
- Mechanism Fennel osmoregulation prevented a sharp fall in relative water content.
- Observation Fennel maintained high chlorophyll index, photosynthesis and transpiration under mild stress.
- Intervention effect Severe stress reduced leaf chlorophyll index by 22%.
- Intervention effect Severe stress reduced net photosynthesis by 24%.
- Intervention effect Severe stress reduced transpiration by 50%.
- Intervention effect Drought increased chlorophyll a fluorescence.
- Intervention effect Severe vegetative stage drought increased Vk and Wk by 44%.
- Intervention effect Severe flowering stage drought increased Vk and Wk by 34%.
- Mechanism Elevated Vk and Wk indicated failure of water splitting in PSII.
- Intervention effect Vegetative drought increased VJ by 16%.
- Intervention effect Vegetative drought increased VI by 22%.
- Intervention effect Reproductive drought increased VJ by 19%.
- Intervention effect Reproductive drought increased VI by 30%.
- Intervention effect PGRs reduced VJ, VI, Vk and Wk.
- Association PGR effects were mainly independent of drought level.
