“…Total soluble solids content in 'Tommy Atkins' mango showed a quadratic behavior (Ferreira et al, 2020), in which the increase in doses promoted an increase in total soluble solids content up to a maximum dose of 1.3 g a.i. linear m -1 of canopy, which correspondeds to 7.64 ºBrix.…”

“…Application of paclobutrazol by irrigation system is more efficient than the conventional application; 1.4 g a.i. linear m -1 of canopy promoted a greater number of fruits and production per plant, in 'Tommy Atkins' mango (Ferreira et al, 2020). Souza et al (2018b), also evaluated 'Palmer' mango and PBZ application via drip irrigation system and reported that the dose of 1.3 g a.i.…”

Application of the plant growth regulator paclobutrazol (PBZ) to aid mango floral induction has been widely performed by mango producers. However, its application has been done manually, resulting in low uniformity of application and losses with labor. The objective of this study was to adjust the PBZ dose to be applied via micro-sprinkler system for floral induction, indicating an efficient management of ‘Palmer’ mango in the Brazilian semiarid. The experiment was conducted at Saúde Farm, located in Petrolina-PE, Brazil. The experimental design used was randomized blocks, with five doses of PBZ, applied via irrigation system (T1 - 0.56; T2 - 1.12; T3 -1.68; T4 - 2.24; and T5 - 2.80 g a.i. linear m-1 canopy) and a conventionally applied dose (T0 - 2.80 g a.i. linear m-1 of canopy, manually applied broadcast), with four replicates. The variables analyzed were: photosynthesis rate, stomatal conductance, transpiration, leaf temperature, number and length of panicles, number of fruits per plant, average fruit weight, yield, pulp firmness, titratable acidity and total soluble solids in the fruits. At the conventionally applied dose (2.8 g a.i. linear m-1 of canopy), PBZ application via micro-sprinkler irrigation system proved to be the most efficient way to reduce photosynthesis rate, stomatal conductance and transpiration. PBZ applied via micro-sprinkler irrigation system at a dose of 0.56 g a.i. linear m-1 of canopy promotes greater number of panicles and yield in ‘Palmer’ mango.

“…The nutrients N and K show high mobility in the phloem and a large degree of translocation (Silva et al, 2020;Sampaio et al, 2021). As the reproductive organs have priority, these nutrients are commonly mobilized from the leaf to the fruit (Dias et al, 2013).…”

The São Francisco Valley region of Brazil is a leading exporter of mango fruits. Previous nutritional diagnosis can identify stresses, provide adjustments for nutritional limitations, and promote more efficient fertilization and nutrient management. This study aimed to compare the nutritional diagnosis of mango trees in the post-harvest and pre-flowering phases and to correlate them with productivity. Norms and indices of the Integrated System of Diagnosis and Recommendation (DRIS), as well as the Nutritional Balance Index and the Potential of Response to Fertilization were generated for each phenological phase of the mango trees. Optimal concentrations and ranges of nutrients were established, classified as deficient, balanced, or excessive, and subsequently compared to each other and to values recommended in the literature. The indices were correlated with the productivity of the orchards in each phenological phase of the mango trees. When comparing the DRIS norms of post-harvest and pre-flowering phenological phases, 55% of the averages differed. The sufficiency ranges of the post-harvest and pre-flowering phases were generally different from those referenced in the literature. Nutritional diagnoses for P, K, Ca, Mg, S, Zn, and Cl altered between phenological phases. The nutritional diagnosis performed in the post-harvest phase showed that nutritional imbalance affected productivity.

“…The increase in demand for high-quality mango to meet standards for local, national and international markets has resulted in the designing of new production strategies and techniques that are essential elements for its production in a fast-changing climate. For instance, the amount of rainfall in most producing regions is not adequate to meet mango water requirements, demanding the application of irrigation, biostimulants and paclobutrazol to promote flowering, fruit yield and quality [15][16][17]. Unfortunately, there are a number of bottlenecks that underpin the production of mango.…”

Abiotic Stress in Crop Plants - Ecophysiological Responses and Molecular Approaches

Mango (Mangifera indica) is an economically and nutritionally significant fruit crop in the tropical and subtropical regions. The demand for mango fruits and processed products has been high both in the internal and external markets due to its taste and its associated health benefits. In meeting the demands requirement, reengineering the various tools that are available to improve mango production in response to the varied stresses in their environment, especially in the era of climate change, is crucial. The prime goal is to demonstrate the effects of climate change on mango growth, yield and quality while showing interventions that have been deployed to combat it. The chapter focuses on the role climate variability plays in the growth and yield parameters of mango trees, as well as the improvement objectives and approaches employed in enhancing their production and quality. It offers the diverse progress made in overcoming the biotic stresses that hinder mango production as well as the intervention made in improving the nutritional and quality traits of mangoes while offering directions for future research works on mango trees.
