Other claims from this paper (8)
- Intervention effect Under water deficit, olive plants lower the water content and water potentials of their tissues, creating a high potential gradient between leaves and roots.
- Intervention effect Under water deficit, olive plants stop canopy growth.
- Intervention effect Under water deficit, olive plants do not stop photosynthetic activity and transpiration.
- Observation Under water deficit, olive plants continuously produce assimilates and accumulate them in the various plant parts.
- Intervention effect Under water deficit, olive plants develop a higher root/leaf ratio than well-watered plants.
- Mechanism Active and passive osmotic adjustment from accumulated mannitol, glucose and proline is key to maintaining cell turgor and leaf activity in olive trees.
- Intervention effect At severe drought stress, the non-stomatal component of photosynthesis in olive trees is inhibited.
- Intervention effect At severe drought stress, photosystem II in olive trees undergoes light-dependent inactivation.
