“…Plants being highly susceptible to environmental conditions, maintenance of better water status is a prerequisite for drought stress recovery (Blackman et al 2009;Dien et al 2019;Ammar et al 2020). Effective osmotic regulation during drought stress helps to maintain better plant water status and to reduce the membrane damage caused by drought in primed plants (Farooq et al 2009b).…”

“…Photosynthetic recovery is the immediate result of re-watering. The extent of stress recovery relies on the pre-drought intensity, duration and plant species (Rivas et al 2016;Ammar et al 2020). During drought recovery, plants restore their photosynthetic activity, which can be noted as an increase in the rate of photosynthesis (Zhang et al 2018).…”

“…During drought recovery, plants restore their photosynthetic activity, which can be noted as an increase in the rate of photosynthesis (Zhang et al 2018). Two weeks of drought exposure followed by re-watering resulted in the formation of new leaves, and thereby improve stomatal conductance, chlorophyll content, and net photosynthetic rate of Ficus carica (Ammar et al 2020). Similar results were also seen in the case of maize seedlings subjected to recovery from drought stress, wherein recovery was indicated by the higher chlorophyll content and maximum quantum yield of PSII photochemistry (Fv/Fm) and lesser injury of photosynthetic apparatus (Chen et al 2016).…”

“…Studies showed that the rate of recovery largely depends on pre-stress exposure. According to Ammar et al (2020), the plants subjected to earlier stress regain their growth through the emergence of new leaves and subsequently improved photochemical activities during stress recovery than the plants that did not encounter any past stress experience. This finding suggested the role of pre-stress exposure in the recovery kinetics of plants.…”

“…Most drought events are brief in nature and are followed by favorable conditions enabling the recovery of plants from stress. At the onset of recovery, most of the modifications induced by drought are reverted to the initial state, and plants try to recover from the damages caused by drought (Zhang et al 2018;Ammar et al 2020). The extent of damages induced by the stress determines the recovery kinetics of plants, depending on the threshold in which the plants may be able to re-establish homeostasis upon new minimum favorable conditions (Rivas et al 2016).…”

Drought stress exposure adversely affects plant growth and productivity. Various seed priming techniques are experimented to mitigate the adverse effect of drought stress on plant performance. It is a low-cost and sustainable technology that proved to be of immense potential to enhance drought tolerance and increase crop productivity. Drought episodes are followed by recovery through rain or irrigation and help the plants to recuperate from the damages caused by drought stress. The severity of drought-associated damages determines the recovery kinetics of plants. Under the recurrent cycle of drought events, recovery kinetics has immense importance in predicting the stress tolerance potential and survival status of a plant. Many processes like DNA damage repair, de-novo synthesis of nucleic acids and proteins, osmotic adjustment through the accumulation of osmolytes, the potential activity of antioxidant machinery occurring during seed priming play a significant role during recovery from drought stress. Alleviation of the severity of drought stress through the accumulation of osmolytes, the augmented activity of antioxidant machinery, improved photosynthetic performance, and the upregulated expression of stress-responsive genes attributed by seed priming will complement the recovery from drought stress. Although the beneficial effects of seed priming on drought tolerance are well explored, priming influenced recovery mechanism has not been well explored. There is a lacuna in the field of research related to the beneficial effects of seed priming for recovery from drought stress, and that is the focus of this paper.

Compare water stress tolerance traits between different fruit tree species under the same experimental conditions can provide valuable information for understanding the mechanisms underlying water stress tolerance. This work aimed to determine and compare the water stress tolerance of six fruit tree species typically cultivated in Mediterranean regions and evaluate its association with water use and growth under water de cit. Six fruit tree species were used in this study: pomegranate, g, mandarin, avocado, and two Prunus species ('R40' and 'R20'). Iso-anisohydric behavior (low to high water stress tolerance) was assessed through a multi-trait approach and associated with growth and water use under wellwatered and water de cit conditions. Avocado and mandarin were classi ed as species with more strict stomatal control over water potential, while pomegranate, g, and Prunus spp. showed less stomatal control. This classi cation was supported by the multi-traits analysis, which showed that avocado and mandarin, in contrast to the rest of the species, were characterized by higher gas-exchange thresholds (more sensitive). A more isohydric behavior was associated with lower water, but higher root hydraulic conductivity, and a lower growth capacity. Some traits, such as the FTSW threshold to the drop of relative transpiration, root hydraulic conductivity, and residual soil water content, provide valuable information to discriminate between species or genotypes that are better adapted to water de cits. These traits explain the position of the species in the iso-anisohydric spectrum and allow us to understand and develop better strategies for water management in agricultural systems.
