摘要

Climate change is expected to raise the frequency of severe droughts in numerous areas, which it is necessary to know how crop species respond during water scarcity. The purpose of the present investigation was to study the effects of water deficit on morpho-physiological traits, vegetative growth and fruit production of young sweet cherry plants (Prunus avium L. ‘Bing’). Two water treatments were applied: water deficit (WD) received 30% of the amount of irrigation compared to controls (well-watered, WW). After 90 days of application of the treatments gas exchange, water relations, morpho-structural leaf traits, vegetative growth and fruit production of young plants of P. avium L. 'Bing' were evaluated. Overall, a strong decrease of stomatal conductance, transpiration and water potentials was registered. In contrast, young plants subjected to water deficit maintained leaf hydraulic conductance, likely due to their higher vein density. Young plant’s fruit production and cumulative vegetative growth were similar for both treatments. The results suggest that young plants of P. avium L. ‘Bing’ can tolerate water deficit, as vegetative growth and fruit production remained similar to those in fully irrigated plants. Understanding the impact of water deficit on fruit trees is essential for making informed decisions in production and marketing, ensuring the sustainability and profitability of fruit crops in an environment of climate change and limited water resources.
