Mango (Mangifera indica L.) is broadly grown in tropical regions and can also be cultivated in irrigated subtropical semi-arid areas; however, water shortages are a serious problem in the latter region. Among biotic and abiotic factors, water supply is one of the most crucial elements that determine productivity. The allocation of water will be an ever-increasing source of pressure because of vast agricultural demands under changing climatic conditions. Although the mango is considered to be tolerant to drought, water stress during growing cycle can reduce productivity. Here, we review the recent progress in evaluating and augmenting mango water productivity. Developments in physiological and agronomic understanding that have led to a boost in water productivity are presented. In addition, this review deals with deficit irrigation strategies to elucidate the effects on mango yield, water use efficiency, and the response of physiological indicators to water stress. Our main findings were as follows: (1) Under a changing climate, traditional irrigation based on water balance will not be sustainable in the medium/long term; (2) deficit irrigation strategies applied to mango can save irrigation water by up to 40% and improve water use efficiency by up to 30%; and (3) there is valuable potential for further improvement owing to advanced knowledge in terms of the physiological response of mango to water stress, and there are good prospects within the current approaches if they are associated with specific environmental physiology. We concluded that under current medium-/long-term perspectives regarding available water resources, particularly in arid and semi-arid regions, there is an urgent demand for adaptive and water-saving strategies. Thus, it will be vital to redesign irrigation schemes in areas where water is scarce to adjust deficit irrigation strategies not only to save water, enhance water use efficiency, and maintain yield, but also to produce fruits with improved quality.

“…Gibberellin biosynthesis inhibition caused by PBZ and, eventually, stimulation of other plant hormones results in physical and metabolic alterations at the cellular level (Rademacher, 2015). PBZ treatment can result in a reduction in the cell elasticity coefficient, restricting cell elongation (Saxena, Singh, & Rajan, 2017), mainly due to lignin accumulation (Kamran et al, 2018). Together, these responses can reflect an internode growth restriction.…”

The aim of this study was to verify if a growth reduction of yellow passion fruit seedlings’ growth morphophysiology and quality could be changed by paclobutrazol applied through seedling immersion. The experiment was conducted in a greenhouse, with seedlings grown in polyethylene tubes (290 cm3), with substrate. At 40 days after sowing, the seedlings were immersed in an aqueous solution of paclobutrazol at concentrations of 0, 50, 100, 150, and 200 mg L-1. The experiment was conducted in a randomized block design, with five treatments (paclobutrazol concentrations) and four replicates. At 15 and 30 days after treatment, growth characteristics were evaluated. At the end of the assay, destructive evaluations related to mass determination, total leaf area, and seedling quality index were performed. Paclobutrazol treatment induced restrictions in seedling growth, except for fresh and dry mass of root and total fresh mass. Based on these characteristics, the increase in values induced by paclobutrazol was verified. The seedling quality, defined by the major value of the Dickson quality index and a smaller robustness index, was higher when submitted to paclobutrazol treatment.
