ABSTRACT Although mango is one of the tropical fruits of greater interest in the world trade, literature concerning their rootstocks (characteristics and utilization) is scarce. This study aimed to characterize mango plants from cv. Imbú, widely used as rootstock in the Zona da Mata region, State of Minas Gerais (MG), Brazil. Though fruits of this cultivar do not present desirable commercial characteristics, this study allowed us to characterize part of plant morphology and fill a gap in the literature, providing subsidies for future investigations. For such, 'Imbú' plants (˜ 4-years old) from the collection of the Universidade Federal de Viçosa, located in Viçosa -MG were evaluated. The descriptors were: (i) leaf blade division;(ii) leaf composition; (iii) petiole length in relation to leaf blade; (iv) phyllotaxis, (v) leaf position in relation to the branch insertion; (vi) leaf shape; (vii) leaf apex and base angles; (viii) leaf margin category; (ix) venation; (x) leaf length and thickness; (xi) leaf length/thickness ratio; (xii) leaf texture; (xiii) leaf fragrance; (xix) leaf color. The leaves were depicted as lanceolate, with entire margins and sharp angles at the base and apex of the leaf blade. The intensity of the green color of the leaf blade was considered intermediate and the abaxial surface staining showed less intense than that observed in the upper side. The fruits were processed and separated into peel, pulp and seeds in order to evaluate the flesh color, fresh weight and percentage of seeds, peel and pulp. It was determined the soluble solids content, starch concentration, the peel and the pulp color, the cerosity, the percentage evaluation of peel, pulp and seed and the pulp firmness. The average number of germinated seedlings per seed was estimated for 230 sown seeds.

Mango is one of the main fruits grown in Chad. However, it is prone to high post-harvest losses due to lack of adequate distribution networks, appropriate harvesting and conservation methods. The objective of this study was to test the effectiveness of coatings based on extracts of Allium sativum (garlic), Zingiber officinale (ginger) and Spirulina platensis (spirulina) on their conservation. Shelf life, weight loss, firmness, pH and total soluble solids content of mangoes were evaluated. The coated mangoes had excellent brillance compared to control mangoes. The coatings based on the extracts of A. sativum, S. platensis and Z. officinale increased respectively the means shelf life of mangoes to 18, 19 and 24 days. Weight losses were 21% for control mangoes while they were 13% for mangoes coated using mixture containing extracts of A. sativum and S. platensis and 11% for mangoes coated with Z. officinale. Coatings based on extracts of Z. officinale and S. platensis had statistically comparable effects on the firmness of mangoes but significantly higher than those of A. sativum extracts and controls after the 10th day. pH values and total soluble solids content (TSSC) values of control mangoes were significantly higher than those of coated mangoes. On day 10 after treatment, chlorophylls were absent from the peel of control mangoes whereas they were still present in the peel of coated mangoes. The mangoes coated with extract of Z. officinale reached a shelf life of 24 days. This shelf life was significantly higher than that of mangoes coated with other types of extracts and control mangoes. The coating with Z. officinale extract slowed considerably the ripening of mangoes. It can be recommended for conservation of mangoes in fresh.

ABSTRACT The post-harvest quality of yacon tuberous roots produced at different altitudes and planting times were characterized in this study. The experiment was conducted in the South of Espírito Santo State in two locations, one at 837 m altitude and the other one at 113 m altitude. The experimental design, in each place, was randomized blocks with four replications, and the treatments consisted of three planting seasons: April (autumn), July (winter) and September (spring). After harvest of the tuberous roots, we evaluated pH, titratable total acidity, moisture content, soluble solids, reducing sugars, crude fiber and ash, as well as color, hardness (maximum force recorded in the first penetration or compression cycle) and chewiness index (energy required to chew food, given by gumminess x elasticity). Tuberous roots grown at 837 m altitude, independent of planting times, presented higher soluble solids content and lighter juice, conferring better quality. However, at 113 m altitude, from April to July, the roots showed better quality, since it presents lower hardness and lighter juice.

Pyrus Pyraster

&nbsp;A population of 1,149 pear individuals from Slovakia is analysed according to their morphological characteristics of fruits and leaves. Three basic taxa were identified &ndash; Pyrus pyraster, Pyrus amphigenea and Pyrus nivalis. Qualitative traits (shape of leaf blade, fruit shape, type of leaf or fruit base, etc.) allowed the exact identification of a particular taxon only in some cases. Quantitative characteristics of leaves proved to be more suitable for the identification of analysed taxa. Statistically significant differences were found between all studied taxa in the values of leaf length and width, and also in the values of relative characteristics that described the leaf shape. Exceptionally the length of leaf petiole had very variable values (S<sub>x</sub><sub>% </sub>= 25.70&ndash;29.75%), therefore it was impossible to classify the species according to this character. Generally, fruit shapes and dimensions are less representative for taxonomy use although significant differences between all studied taxa were found in the values of fruit length. The correct taxonomic classification of pears cannot be done according to one characteristic. It is important to consider a few of them (shape and length of leaf blade or its slenderness, shape quotients and also the shape and length of fruits) for the appropriate classification of pear individuals. &nbsp; &nbsp;

Fruit Bagging

Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae) is the main pest of mango, Mangifera indica L., in Spain, causing significant economic losses by aesthetic damage that reduce the commercial value of fruit. Bagging fruit with two commercial bags (a yellow satin paper and a white muslin cloth bag) was evaluated for control of A. tubercularis in two organic mango orchards during the 2020 cropping season in pursuit of the development of a mango IPM program to produce pest-free and residue-free fruits. Results from fruit damage evaluations at harvest showed that bagging significantly reduced pest incidence and fruit damage compared with non-bagged plots. Of the two bags evaluated, white muslin cloth bag provided higher levels of fruit protection from A. tubercularis damage, reducing the non-commercial fruit percentage by up to 93.42%. Fruit quality assessment indicated that weight and size of bagged fruit were significantly higher than the non-bagged. Paper-bagged mangoes showed higher whiteness and yellowness compared to the other treatments. Soluble solids content (ºBrix) was higher in paper-bagged fruit than all other treatment plots. The results from this study indicate that pre-harvest fruit bagging is effective at controlling A. tubercularis and should be integrated into an IPM program for Spanish mango production.

Five mangos cultivars (Mangifera indica L., `Palmer', `Keitt', `Spring Field', `Kent', and `Anderson') were harvested at the preclimacteric stage. Fruits were selected for study that were uniform and free of visual defects and stored for 18 days at 10 °C, 90% to 95 % RH. Fruits were evaluated every 3 days for pulp and peel color, total soluble solids, titratable acidity, ascorbic acid content, and total and reducing sugars. Pulp and peel color parameters (lightness, hue, and chroma) were significantly different among cultivars. The soluble solids content, ascorbic acid, and starch content changed significantly during storage and were significantly different among cultivars. Total and reducing sugars content did not change significantly after 10 days of storage. Results of this study indicated that these five mango cultivars have good storage potential.

This study delivers a comprehensive flavonoid fingerprint profile, physiochemical and external color characterization of Plavac Mali grapes through four harvest dates at two distinct vineyards (Split and Zadar) in the Eastern Adriatic region. The experimental harvest lasted 56 days, at total soluble solids content from 18.4 to 22.4°Brix in Split and 16.8 to 20.4°Brix in Zadar. Patterns of 27 skin and seed flavonoid compounds at each location indicate unique flavonoid composition of berries at each harvest date. Extended harvest increased six compounds in skin with maximum values of main anthocyanin malvidin-3-O-glucoside in H3 (4406.6 and 6389.5 mg kg−1, Split and Zadar, respectively) followed by a decrease in October. Peak values of seed and skin catechins and galloylated flavan-3-ol subunits are seen in H1 and H2 at Split, while constantly high values are reported in the case of Zadar, with an incoherent pattern of those in skin extracts. Minimal values of epigallocatechin were detected with an extended harvest date at both locations. Berries of extended harvest dates underwent colorimetric improvements, trough decrease in L*, a*, b* and C characteristics and increase in skin color index for red grapes CIRG. The extended harvest date promotes flavonoid composition, and improves the quality of Plavac Mali grape berries.
