ABSTRACT The present study aimed to describe histological traits of the graft welding process and evaluate the effect of rootstocks on the physical and chemical traits and the productivity of sour passion fruit populations. The experiment was arranged in a randomized block design, in a 4x2 + 4 factorial scheme (cultivars / canopy x rootstocks), three replicates and nine plants per plot. Commercial cultivars and populations and Passiflora alata and P. nitida rootstocks, in addition to ungrafted plants were used as canopy. Cleft grafting was the grafting type adopted. Traits analyzed such as productivity and physical and chemical quality of fruits were submitted to analysis of variance and compared by the Tukey test. The canopy morphology was evaluated according to descriptors of the Ministry of Agriculture, Livestock and Supply. Grafting was carried out for each graft/rootstock combination for histological analysis. Sections were obtained by freehand cuts, stained and mounted on semi-permanent slides, examined under optical microscope and photomicrographed. Rootstocks affected the early cultivation and reduced productivity and number of fruits of passion fruit populations. Grafting did not affect the quality of fruits or the canopy morphology. Considering the complete culture cycle, P. alata species is able to be used as rootstock. The anatomical study demonstrates the occurrence of better compatibility in the connection of P. edulis tissues on P. alata, compared to grafting on P. nitida.

Abstract The interspecific introgression of resistance genes to diseases in commercial varieties through interspecific crosses has been adopted as a strategy in breeding programs of sour passion fruit. This work aimed to evaluate 11 progenies of multispecific hybrids obtained from crosses involving seven Passiflora species, in addition to four commercial cultivars, using the REML/BLUP method. The experiment was carried out as a randomized block design with six repetitions and three plants per plot. Ten fruit traits were evaluated. The additive, multiplicative, and sum of ranks indexes were applied to determine the most appropriate selective strategy in the simultaneous increase of fruit weight, number of fruits, and yield. Plants from the 325 x VAO progeny showed a lower bacterial defoliation index and better means predicted for the traits number of fruits and productivity. The progenies 325 x LD4, PL3 x LD4, and the controls CSB-Marília and BRS-Gigante Amarelo showed plants with better-predicted means for traits related to fruit quality. The genetic gains demonstrated good prospects for the use of wild species in sour passion fruit genetic breeding.

The production of good quality passion fruit seedlings depends on substrates with adequate physical and chemical characteristics. Therefore, this experiment was conducted to evaluate the effect of doses of ash from burning of sugarcane bagasse on improvement of traits of the substrate "gully soil". The experiment was set up in a greenhouse and arranged in randomized block design, in a 2x7x2 factorial scheme. The following factors and their respective levels were studied: (i) soil structure,- aggregating between 4 and 10 mm and <2 mm; (ii) ash doses - 0; 1.5; 3; 6; 12; 24; and 48 t ha-1; (iii) families of passion fruit - F29 and F48. The use of ash combined to the soil with structure <2mm significantly increased the production of shoot fresh mass and shoot dry mass for both families studied. The density of the substrate obtained by the mixture of ash and gully soil (soil) decreased as ash doses increased, regardless of the size of the aggregates and the family studied.

The utilization of brewery waste in ration to improved the quality of lamb meatABSTRACT. An experiment has been conducted to study the utilization of brewery waste in ration to improved the meat quality of lamb. High quality of lamb meat can be reached by manipulation of rumen fermentation. Tannins in brewery waste can decrease the activity of rumen microorganism and inhibite the rumen biohydrogenation processes. The experiment was conducted with an experimental method by in vivo technique, using 16 heads of local lamb, 4-5 months old, with body weight range of 5-10 kg.  The trial was conducted for 150 days, using Completely Randomized Block Design with 4 replicates. The treatment tested were 4 levels of Brewery Waste : R1 = 12%; R2 = 24%; R3 = 36% and R4 = 48%. The variables measured were : physical and chemical quality of meat. The result indicated, that the treatment tested significantly affect the meat quality physically, except to the percentage of edible distal meat and proximal bone weight.Based on the all variables measured, the research conclusion : (1) the utilization of brewery waste up to 48% dry matter  ration, could be used, without any physiology and metabolism disturbance; (2) the highest increasing of unsaturated fatty acid was stearic acid (C18:0) as much as 54. 60%, was reach by R3 (36% brewery waste); the linoleic acid increased as much as 43.91% reach by R4 (48% brewery waste);  the oleic acid increased as much as 37.48% by R2 ( 24% brewery waste). From the result can be suggested that the need of tannin brewery waste as biohydrogenation inhibitor would be more effective and efficient whenever brewery waste usage has been increased up to 60% dry matter ration.

Abstract The use of advanced seedlings associated with the annual cultivation of passion fruit are important management techniques for living with the fruit-hardening virus (FEV). However, this technology still needs information on nitrogen fertilization and spacing between plants, so that it is possible to recover crop’s productivity. The objective of this research was to identify the nitrogen dose (N) and the most suitable spacing for annual orchards installed with advanced seedlings (1.2 m high) of yellow passion fruit. The experiment was carried out in the field, in Mogi Mirim, SP, between October 2017 and July 2018. A randomized block design was used in subdivided plots; the treatments were doses of N in coverage such as 0, 60, 120, 180 and 240 kg ha-1 and spacing between plants of 2.0 and 4.0 m and 3.0 m between lines. The dose found for maximum production, 15.4 kg of fruit pl-1, and adequate physical-chemical quality of the fruit for the yellow passion fruit was 130.7 kg ha-1 of N. The most densified spacing, of 2 x 3 m, provided greater productivity and number of thousand fruits per hectare, respectively, 20.7 t ha-1 and 139.5 thousand fruits ha-1.

ABSTRACT Tomatoes are an important component of the human diet because they are rich in minerals and antioxidants that sequester free radicals in cells, preventing various disorders that affect human health. Here, we aimed to evaluate the effects of different nitrogen sources and concentrations on antioxidant capacity and physical and chemical quality of tomato fruit. The experiment was conducted in Vitória da Conquista, state of Bahia, Brazil, in the experimental field of Universidade Estadual do Sudoeste da Bahia. The experimental setup included a randomized block design with four replicates in a factorial layout of 3 × 3 + 1 (control), for a total of 40 plots. The three treatments comprised different nitrogen sources (calcium nitrate, urea, and ammonium sulfate), applied in three doses (140, 280, and 420 kg ha-1). We evaluated firmness, pH, titratable acidity - TA, soluble solid - SS, SS/TA ratio, ascorbic acid, carotenoids, flavonoids, phenolic compounds and DPPH inhibition, were evaluated after samples were harvested. However, increasing concentrations of N adversely affected the acidity and led to an increase in the SS/TA ratio. Increasing the N concentration also reduced the content of bioactive compounds. excluding carotenoids, which consequently impaired antioxidant activity.

The aim of this study was to verify if a growth reduction of yellow passion fruit seedlings’ growth morphophysiology and quality could be changed by paclobutrazol applied through seedling immersion. The experiment was conducted in a greenhouse, with seedlings grown in polyethylene tubes (290 cm3), with substrate. At 40 days after sowing, the seedlings were immersed in an aqueous solution of paclobutrazol at concentrations of 0, 50, 100, 150, and 200 mg L-1. The experiment was conducted in a randomized block design, with five treatments (paclobutrazol concentrations) and four replicates. At 15 and 30 days after treatment, growth characteristics were evaluated. At the end of the assay, destructive evaluations related to mass determination, total leaf area, and seedling quality index were performed. Paclobutrazol treatment induced restrictions in seedling growth, except for fresh and dry mass of root and total fresh mass. Based on these characteristics, the increase in values induced by paclobutrazol was verified. The seedling quality, defined by the major value of the Dickson quality index and a smaller robustness index, was higher when submitted to paclobutrazol treatment.

The production of compact plants, which are slightly lacking in vigor and as productive as conventionally sized plants, is a trend in fruit growing. The objective of this study was to evaluate the vegetative performance and fruit quality of Gulfblaze and Reubennel plums intergrafted into two peach genotypes (UFV 186 and UFV 286). The experiment was arranged in a randomized block design using a 3x2 factorial arrangement (interstocks x cultivar) with four replications and one plant per plot. The non-intergrafted treatment was considered the control. Ten fruits were collected per plot for physical and chemical analyses. The evaluations were performed in the years 2014 and 2015. The interstock UFV 286 produced Gulfblaze trees with lower height in the two years of evaluation. When using the UFV 286 interstock, the trunk diameters were 50.2% smaller in Gulfblaze and 44.25% smaller in Reubennel than the control cultivars. Intergrafting had no influence on the fruit mass of Reubennel. In general, the peach genotypes UFV 186 and UFV 286 can be recommended as interstocks for reducing plant size in the plums studied. Intergrafting had no effect on fruit quality of Reubennel plums.

ABSTRACT Yellow passion fruit is a fruit species widely cultivated throughout the Brazilian semi-arid territory, but its yield is affected by the quality of the waters of this region. In this context, the objective was to evaluate the gas exchange and production of passion fruit cv. BRS Rubi do Cerrado irrigated with waters of different cationic natures. The study was conducted in drainage lysimeters under greenhouse conditions in Campina Grande, PB, Brazil, in a randomized block design, and the treatments were eight cationic natures of irrigation water (S1 - Control; S2 - Na+; S3 - Ca2+; S4 - Mg2+; S5 - Na+ + Ca2+; S6 - Na+ + Mg2+; S7 - Ca2+ + Mg2+ and S8 - Na+ + Ca2+ + Mg2+) with three replicates. Plants in the control treatment were irrigated with water of low electrical conductivity (ECw = 0.4 dS m-1), while those of the other treatments were irrigated using water with ECw of 3.5 dS m-1. The treatments Na+ + Ca2+, Na+ + Mg2+ and Ca2+ + Mg2+ were prepared in the equivalent ratio of 1:1, and Na++Ca2++Mg2+ in the ratio 7:2:1, respectively. Water salinity of 3.5 dS m-1 reduced gas exchange, and stomatal conductance and transpiration were the most sensitive variables of passion fruit. The number of fruits of passion fruit cv. BRS Rubi do Cerrado decreased with water salinity, regardless of the cationic nature. The waters of calcic and calcic+magnesian nature caused the greatest deleterious effects on the production variables of passion fruit, at 259 days after transplanting.
