dc.description.abstract | Quince tree (Cydonia oblonga Mill.) is known for bearing fruits that are rich in nutrients and health-promoting
compounds while requiring low inputs of agrochemicals, and maintenance, but no information exists on the
mechanisms developed at the level of leaf water relations to confront water stress and recovery. For this reason,
the purpose of the present study was to identify the strategy (isohydric or anisohydric) by which quince plants
cope with water stress and to further elucidate the resistance mechanisms developed in response to water stress
and during recovery. In summer 2016, field-grown own rooted 17-years old quince trees (cv. BA-29) were
subjected to two irrigation treatments. Control (T0) plants were drip irrigated (105% ETo) to ensure non-limiting
soil water conditions, while T1 plants were irrigated at the same level as used in T0, except that irrigation was
withheld for 42 days during the linear fruit growth phase, after which irrigation returned to the levels of T0
(recovery period). During the experimental period, T0 and T1 received a total of 374 and 143 mm water, re spectively, including rain water. The quince trees exhibited extreme anisohydric behaviour under the experi mental conditions. As water stress developed and during the recovery period, the plants exhibited high hydraulic
conductivity, probably the result of resistance to cavitation. From the beginning of water stress to the time of
maximum water stress, leaf turgor was maintained, possibly due to active osmotic adjustment (stress tolerance
mechanism). This leaf turgor maintenance may have contributed to the high leaf conductance, and, therefore,
good leaf productivity. The low quince leaf apoplastic water fraction under water stress could be considered as
another drought tolerance characteristic because if the accumulation of water in the apoplasm is avoided a
steeper gradient in water potential between the leaf and the soil can take place under water stress, thus favouring
water absorption | es |
