“…Pearson's correlation analysis revealed a significant correlation (P # 0.01) between total soluble carbohydrates and foliar boron (r = 0.58), total soluble carbohydrates, and panicle length (r = -0.59) and a significant correlation (P # 0.05) between foliar calcium and number of fruits per panicle (r = 0.54). Faria et al (2016) reported similar responses to those found in this work for chlorophyll a, b, and total contents. In their work, the authors studied different irrigation management of 'Tommy Atkins' mango trees cultivated in a semiarid region and reported maximum values of chlorophyll a, b, and total as 36.23, 15.12, and 51.35, respectively.…”

Adequate nutritional status is fundamental for the fruiting process of mango trees (Mangifera indica L.). In this context, plant biostimulants are substances that promote physiological and nutritional changes, benefiting production. The present study evaluated the effect of biostimulants on the nutritional status and fruit production of ‘Kent’ mango trees. The experiment was carried out in the Brazilian semiarid region over 2 consecutive years, 2016 and 2017. Leaf treatments with biostimulants were applied in three phases (preflowering, beginning of flowering, and full flowering) during both seasons. The treatments were as follows: T1) control (without biostimulants); T2) biostimulants containing nutrients and L-α-amino acids; T3) biostimulants containing nutrients and Lithothamnium algae extract; T4) biostimulants containing nutrients and sucrose; and T5) biostimulants containing nutrients, free amino acids, and Lithothamnium algae extract. The results show that there was no effect of the biostimulants for chlorophyll a, b, and total indices or for total leaf soluble carbohydrates. Some of the treatments affected the leaf concentrations of N, K, Mn, Fe, and Zn, whereas only T2 in 2016 and T5 in 2017 increased the number of fruits per panicle if compared with nontreated plants. In 2016, the production per tree was higher in T5 compared with the other treatments, whereas it was greater in 2017 in both T2 and T5 with increases of 37.4 and 23.1 kg per tree, respectively, compared with the control treatment. Biostimulants containing soluble nutrients, L-α-amino acids, free amino acids, and Lithothamnium algae extract benefit the nutritional status and increase the fruit production of mango ‘Kent’.

“…These cations have high osmotically active properties, therefore Ewais variety considered more tolerate than Zebda variety, specially, Cu and Fe which play an important role as antioxidants, as well as, have a pesticide effect against land snail and fungi (Saleh, 2016). Also, B, Ca and Zn cations considered metabolite regulators (Faria et al, 2016).…”

“…Wongmetha et al (2015) stated that sucrose metabolism and starch storage in mango were depended on growth stage, development in mango fruits, decrease activity of sucrose phosphate syntheses, acid invartase (AI) and neutral invartase (NI). Faria et al (2016) revealed that the content of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Zn and Na concentration in mango leaves as well as total chlorophyll, contents of a and b were depended on treatment strategies, growth stages and time of sampling. This study was carried out at El-Kassasin, Ismailia Governorate, Egypt to compare physiological and biochemical properties between two mango cultivars i.e., Ewais and Zebda.…”

This study was conducted at Ismailia Governorate, Egypt. The investigation aimed to evaluate physicochemical characteristics of two mango cultivars i.e., Ewais and Zebda (Mangifera indica L.). Mango trees, 10 years old (planting distance 7 × 7 m) from each cultivar were selected to be nearly size and being in their off bearing. Leaves at different stages of growth and fruits were investigated. Results revealed that, Ewais leaves have phenolic compounds from 80.36 to 92.82 (mg ̸ gfw), Cytokinin from 3.60 to 4.41 (ng/gfw), gibberilic acid from 28.58 to 36.61 (µg/gfw), absisic acid from 8.44 to 9.5 (µg/gfw), total protein from 4.38 to 9.13(g ̸ 100 gdw), total free amino acids from 23.72 to 36.70 (m mol ̸ 100 gdw), total protein from 5.83 to 7.22 (µmol ̸ gfw), total carbohydrate from 18.76 to 21.09 (g ̸ 100gdw), total chlorophyll from 1.55 to 2.11 (mg/gfw) and total carotenoid from 0.82 to 0.98 (mg/gfw). Enzymes activities (mmol ̸ gfw) in Ewais leaves were as follow, catalase between 26.23 and 50.31, peroxidase between 1.23 and 2.80, polyphednol oxidase from 101 .29 to 106.62 and amylase from 7.13 to 8.1. These results dependant on growth stages and were superior for Zebda cultivar. Ewais cultivar has higher yield (yield ̸ tree, kg) (92.82) than zebda (89.27). Fruits of Ewais have a higher performance parameters than fruits of Zebda.

“…These variables influence growth, developing, and yielding (Santos and Martinez, 2013). There is some research in the literature on the use of water-deficit strategies in mango trees grown in semi-arid regions of Brazil and how it relates to gas exchanges (Santos et al, 2016b;2016c;Santos and Martinez, 2013), to root distribution (Santos et al, 2014a), to water uptake (Santos and Martinez, 2013), to flower induction (Faria et al, 2016a), and to leaf nutrient content (Faria et al, 2016b). Nonetheless, information regarding sap flow as an alternative to determine water demand of mangoes under deficit irrigation is lacking.…”

Knowledge of transpiration is of fundamental importance for improving irrigation management. This study measured sap flow of the 'Tommy Atkins' mango tree using Granier’s thermal dissipation probe method under regulated deficit irrigation. The work was conducted in a 10-year-old ‘Tommy Atkins’ mango orchard, irrigated by micro sprinkler, located in the Irrigated Perimeter of Ceraíma, in Guanambi, Bahia, Brazil. Sap flow measurements were carried out on three consecutive days in plants under regulated deficit irrigation, with reductions of 30 and 60% of crop evapotranspiration in three phases of fruit development; beginning of flowering to early fruit growth (Phase I), fruit expansion (Phase II) and physiological maturation of fruits (Phase III). Regulated deficit irrigation led to reduced sap flow in ‘Tommy Atkins’ mango tree.
