Objective: To identify the morphometric and biochemical variation in mango fruits var. Ataulfo (Mangifera indica L.) in two contrasting environments with and without conventional management. Design/methodology/approximation: Morphological and biochemical variables were studied in mango fruits var. Ataulfo in two environments, one of them (La Norteña) with Leptosol soil and Aw climate with conventional agrochemical-based management and the other (Santa Cecilia) on Acrisol soil and Am climate with agroecological management. There were 30 fruits used, all from five trees (n=150) per study garden in a state of commercial maturity. Each fruit was considered as an experimental unit, and morphological and biochemical variables were evaluated for each fruit. Results: Increase in fruit weight, higher pH and increase in total soluble solids, but decrease in pulp weight on site with conventional handling. Increase in pulp content and firmness in fruits from the site without handling. Study Limitations/implications: Changes in the amount and distribution of rainfall in both environments each year. Findings / conclusions: Morphological and biochemical modifications are presented. Greater size and weight, pH and TSS content in the conventional production system, but increased pulp and greater firmness, as well as higher citric acid content in the agroecological system. The results suggest differential effects in mango fruits according to the management and environment where they develop.

Yield And Quality

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.

Over three years the postharvest quality of 'Marli' peaches harvested from the integrated (IFP) and conventional production (CFP) systems was evaluated. The peaches were harvested from commercial orchards of Prunus persica at two locations close to the city of São Jerônimo, RS, Brazil, and stored at 0.5°C for 10, 20 or 30 days. The peaches were evaluated at harvest, at retrieval from storage and after ripening periods at 20°C. No differences in fruit weight losses were determined. Decay incidence was low, and no differences were detected amongst systems in both 2001 and 2002 seasons, but in the 2000 season CFP peaches were more decayed. Flesh firmness of peaches from the IFP system were greater than CFP fruits in the years 2000 and 2001. In 2002, firmness changed little during storage and ripening. Peaches from the IFP in 2000 had higher titratable acidity and lower soluble solids. In the 2000 season, flesh browning was observed in decayed fruits, always at ripening after 20 or 30 days of cold storage Chilling injuries such as browning, woolliness and leatheriness ocurred in 2002. There were no differences amongst systems related to peach quality.

The aim of extending shelf-life and maintaining quality is one of the major issues regarding mango fruit preservation. The quality of mango fruits is greatly affected by postharvest factors, especially temperature and fruit treatment. In this study, the effect of coating and storage temperature on the characteristics of mango fruits was investigated. The mango fruits were immersed in different concentrations (1.5%, 2.0%, and 2.5%) of pectin/nanochitosan dispersion (with ratios of pectin:nanochitosan 50:50), and (0.75%, 1% and 1.25%) of nanochitosan dispersion and stored at 17, 25, and 32 °C for 24 days. Changes in fruit, including weight loss, firmness, color, chemical composition (such as the total soluble solids concentration (TSS)), total sugar, reducing sugar, titratable acidity (TA), and vitamin C were periodically recorded. The results indicated that the pectin/nanochitosan coating significantly prevented reductions in the fruit weight, firmness, TSS, TA, and vitamin C content. Additionally, pectin/nanochitosan at a low temperature (17 °C) had a greater positive effect on fruit shelf-life and weight maintenance than 25 and 32 °C. The coated mango fruits maintained good quality for 24 days at 17 °C, while coated fruits stored at 25 °C and 32 °C, as well as uncoated ones stored at 17 °C, were destroyed after two weeks. At the maximum storage time evaluated, the coating formulations containing pectin and nanochitosan exhibited microbial counts below the storage life limit of 106 CFU/g of fruit. In general, the results showed that the pectin/nanochitosan coating (2%) with a storage temperature of 17 °C is the most effective strategy for improving quality and extending the shelf-life of mango fruits.

Fruit Bagging

Mango (Mangifera indica L.) is famous among all fruits because of its taste, variety and color. However, the quality of mango fruits is mainly deteriorated by insect-pests complex. The study was performed to evaluate bagging effects on insect-pests complex, yield and quality of mango fruits at private mango orchards located in Multan district. A mango cultivar, Anwar Rataul was selected, and the fruits were bagged during 1st week of May (at stone size stage) to 1st week of July 2017 (at maturity stage). The results indicated that the attack of fruit flies and other insect-pests complex were zero in bagged fruits. It was further recorded that the maximum average fruit weight i.e. 203.50 g was noted in those where butter paper bag was wrapped as compared with brown paper bagged fruits having 197.83 g and un-bagged fruits with 159.50 g per fruit. However, brown paper bag resulted in better fruit color development. Similarly, average fruit lengths were greater i.e. 91.33 and 90.18 mm in butter paper and brown paper bagged fruits, respectively as compared to 85.33 mm in un-bagged fruits. Bagged fruits had higher total soluble solids and slightly lower titratable acidity as compared to un-bagged fruits. Further, bagged fruits had no cracks, sunburn, mechanical injury, bird damage, skin blemishes and agrochemical residues. So, it is concluded that fruit bagging on mango cv. Anwar Rataul trees at stone size stage proved to be an effective practice against insect-pests complex and for quality production of fruits for export purposes.

ABSTRACT Currently, tomato is one of the most cultivated crops worldwide, with the highest economic value, increasing its demand and, thus, its expansion, production, and trade. The tomato crop is susceptible to attack of pathogens with devastating consequences on the decline in yields from 50 to 100%. For this reason, new production methods are proposed such as grafting in wild rootstocks, which have high genetic variability and genes responsible for resistance to fungi, bacteria, viruses, and nematodes. The aim of this study was to evaluate the effect of grafting commercial tomato cultivars onto cherry tomato genotypes on yield and fruit quality. The experiment was arranged in a completely randomized design with four replications. The experimental unit consisted of four plants. spaced at 0.9 m between rows (channels), 0.30 m between double rows, and 0.4 m between plants. The treatments consisted of the combination of the following factors: three promising rootstocks (IAC391, IAC426, and LA2076), two commercial scions (Calima and Torrano), two grafting methods (cleft and splice), and two ungrafted commercial controls. Yield components, soluble solids content, percentage of fruit quality, and average fruit weight were evaluated. IAC391 was the most promising rootstock, reaching productions similar to those of the controls. The cleft grafting method, reached a success rate of 98.3%. The commercial scion Torrano stood out for achieving the highest yields.

Fruit Bagging

A study was performed during 2016 from January to July for safe mango production by applying the minimum use of pesticides. The mango fruits were bagged at marble stage (45 days after fruit set) with various treatments viz: T0: No bagging (control), T1: Brown paper double-layered bag (BPB); T2: White paper single-layered bag (WPB); T3: Perforated polythene bag (PB) and T4: White cloth bag (WCB). In physical parameters, brown and white paper bag recorded the maximum fruit weight (169.10 g and 147.6 g), fruit length (8.57 and 8.33 cm), fruit diameter (5.63 and 5.87 cm) and pulp weight (124.47 g and 105.60 g) respectively, while minimum result was found in the other treatments and control. Meanwhile, in bagging fruits, chemical parameters of total soluble solids, ascorbic acid, percent of citric acid, reducing sugars and β- carotene were increased over control. Brown paper bag changed fruit color. The sensory qualities in fruits of brown and white paper bags were improved over control. Fruit retention was significantly improved by pre-harvest fruit bagging with a brown paper bag (95.90%), white paper bag (95.50%), and control (90.00%) over polythene bag (80.00%). Fruits with brown paper bags showed shelf life up to 18 days with good physical quality and the lowest weight loss against 15 days of control fruits. The sensory attributes were better in fruits of brown, white paper and white cloth bags over control. Bagging at marble stage also reduced the occurrence of spongy tissue and the incidence of mealy bugs. These results indicate that fruit bagging can improve the quality and the shelf life of mango cv. Amrapali through the reduction of disease and insect-pest attack.
