“…O maracujazeiro amarelo (Passiflora edulis Sims) é a principal espécie da família Passifloraceae cultivada no Brasil, devido às características físico-químicas dos frutos, alta produtividade e grande aceitação do suco no mercado nacional (Cavichioli et al, 2011;Santos et al, 2014 (Abreu et al, 2009;Rocha et al, 2013).…”

The quality of yellow passion fruits is affected by genetic and exogenous factors like climate, soil and agricultural practices such as fertilizing and irrigation. Thus, an experiment was developed from February to December 2013 to evaluate the effect of nitrogen fertigation and humic substances on physical and chemical quality of yellow passion fruits. The experimental design used was in complete blocks design with subdivided plots with N rates (180, 200, 260, 330 and 350 kg ha-1 year-1) in parcels and application of humic substances (with and without) in sub-parcels, with five repetitions of six plants. At 210 days after transplanting all fruits were harvested and conducted to the laboratory for evaluation of fruit mass, longitudinal and transversal fruit diameter, skin thickness, pulp percentage, pulp pH, vitamin C, soluble solids, titratable acidity, and soluble solids/titratable acidity ratio. Fruits produced, independently of the treatment, are adequate for consumption as in natura or processed fruit. It is possible to recommend a dose of 260 kg ha-1 of N without humic substances for production of good quality yellow passion fruits.

“…The market for fresh blackberry has preference for large fruits, as is the case cultivars Tupy, Chickasaw, and Navaho. Additionally, this size may also be a parameter for determining the harvest point in fruits that should be harvested early processing (Cavichioli et al, 2011).…”

The purpose of this study was to evaluate the phenological behavior and agronomic potential of blackberry varieties and hybrids in a subtropical region. Blackberry seedlings of four varieties and two hybrids were purchased in April 2015 in the form of stem cuttings and transplanting in July 2015. Winter pruning was carried out on August 18, 2016 and 2017. The experimental design was composed of a randomized complete block design, containing four varieties and two hybrids, four blocks and five useful plants per experimental unit. The harvest was performed every two days to the determination of fresh biomass, longitudinal and transverse diameter, volume, number of fruits per plant, yield and estimated productivity. The average duration of the phenological cycles in the two harvests varies between 109 and 162 days and 114 and 148, respectively. Hybrids Boysenberry and Olallie presented a shorter cycle in both harvests. In the 2016/2017 crop, the harvest lasted from 39 to 88 days. In the 2017/2018 harvest, it lasted 23 to 57 days, starting in mid-November through early January. The Tupy and Chickasaw cultivars were the most productive in the first crop. In the second crop, the Tupy and Navaho cultivars were prominent.

“…The value of TA (%) in "Pera" oranges ranged between 1.14% and 0.12% (Lim et al, 2007). For Passion Fruit, the Total Titratable Acidity (TTA) in a work that evaluated the characteristics of this fruit ranged between 3.9% and 4.4% (Cavichioli et al, 2011). In a study of characterization of mango tree fruits, the TA for "Palmer" mango was 0.20% (Silva et al, 2009).…”

Phenolic compounds are natural antioxidants and can be found with abundance in fruits and vegetables. One of the first methods created for analyzing phenolic compounds was the Folin-Denis method; and hereafter, the Folin Ciocalteu method was developed and recently, one of the most recent method is the Fast Blue. Due to the importance of these compounds in food, this work aimed to determine the total phenolic compounds in three fruits, such as: Passion Fruit, “Palmer” mango and “Pera” orange. In addition, these fruits were analyzed through three different determination methods. Furthermore, the content of vitamin C, soluble solids, titratable acidity and pH of these fruits were evaluated. Based on the results, it was verified that there was no difference among the values of vitamin C, soluble solids and TA in relation to those found in the literature. When comparing the three methods (Fast Blue BB, Folin-Ciocalteu Reagent and Folin-Denis Reagent), the results showed a difference in the phenolic compounds that may be related to the distinct reagents used in each method and its different action.
