Physico-chemical properties of different formulations of pequi pulp with milk
Get PDFThe objective of this work was to perform the physical-chemical characterization of different formulations of the pequi pulp with the addition of different concentrations of whole milk, in order to identify promising products for commercial use. Three formulations of pequi pulp with whole milk were prepared: PL1- 90% pequi pulp and 10% milk, PL2 - 70% pequi pulp and 30% milk, PL3 - 50% pequi pulp and 50% milk. The formulations were evaluated for physical and physical-chemical parameters of color, water activity, water content, ash, total soluble solids (SST), pH, total titratable acidity (ATT), SST/ATT ratio, ascorbic acid, proteins, lipids, total, reducing and non-reducing sugars. The data obtained were subjected to analysis of variance (ANOVA) and comparison between means by the Tukey test at 5% probability. Among the three tested formulations, the best results were obtained for PL3, where it presented lower total titratable acidity, water activity, red intensity, yellow intensity and chromaticity, however, higher content of total soluble solids, ratio SST/ATT, ash, lipids, sugars (total, dimmer and non-dimmer), luminosity and tint angle. The inclusion of milk in the pequi pulp changed the physical and physical-chemical characteristics of the pulp, and it can be an alternative to add nutritional value to the fruit and consequently a promising product for the market.The objective of this work was to perform the physical-chemical characterization of different formulations of the pequi pulp with the addition of different concentrations of whole milk, in order to identify promising products for commercial use.

Controlled-release fertilizer increases growth, chlorophyll content and overall quality of loquat seedlings
Get PDFEriobotrya japonica (Thunb.) Lindl. (Rosaceae), commonly known as the loquat tree, is widely cultivated due to production of edible fruits, which can be consumed fresh or processed into different food products. Enhancement of loquat seedlings quality is an important issue for more efficient propagation protocols, including rootstock production. The objective with the present study was to assess the effects of increasing doses of controlled-release fertilizer on loquat seedlings growth, quality and chlorophyll content. Seeds were sowed in containers filled with commercial substrate previously treated with different doses of controlled-release fertilizer (N, P, K, Mg, S and micronutrients): 0.0 (control), 2.5, 5.0, 7.5 and 10.0 kg per cubic meter of substrate (kg m-³). Seedlings were evaluated 182 days after sowing and the data were submitted to polynomial regression analyses. Increasing doses of the fertilizer promoted increasing linear behavior on seedlings height, root collar diameter, leaf area, roots and shoots dry mass and Dickson quality index. Chlorophylls a, b and total chlorophylls increased up to the dose of 7.5 kg m-³, followed by a decrease at the dose of 10 kg m-³. The dose of 10 kg m-³ promoted the highest values of Dickson quality index and growing variables on loquat seedlings.Eriobotrya japonica (Thunb.) Lindl.

Macronutrient fertilizers on basil growth and yield
Get PDFThe objective of this work was to determine the macronutrient doses that allow the highest phytomass yield and growth of basil plants. The experiment was carried out in the experimental area of the Federal University of Recôncavo da Bahia, in Cruz das Almas, BA, in a greenhouse. The treatments were obtained according to the Baconian matrix statistical arrangement, in which one of the nutrients is supplied in variable amounts, while the others are kept at a referential level. Six nutrients (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S)) were evaluated in three different doses, and two additional treatments, one with reference doses and another without nutrient addition, totaling 20 treatments that were arranged in a completely randomized design with five replications, totaling 100 experimental units. At 50 days after treatment distribution, the growth parameters were evaluated: Plant height, number of leaves, leaf dry mass, stem, root and leaf area. It was observed that the highest leaf dry mass accumulation was estimated with the dose of 250 mg dm³ of N giving an average of 8.01g per plant, being significantly higher when compared to all other tested elements, this parameter is extremely relevant because the leaves are characterized as the main product of this species. Phosphorus doses allowed significant results in height and leaf area, whereas K favored higher leaf emission. Positive responses were verified for nutrients Ca, Mg and S in all parameters tested at levels above those tested as reference.The objective of this work was to determine the macronutrient doses that allow the highest phytomass yield and growth of basil plants.

Biometrics, physiology, production, and quality of Cantaloupe melons grown with saline waters under semi-arid conditions
Get PDFBrazilian Northeast region emerges as both producer and exporter relevant of cantaloupe melon to several countries; however, this region is vulnerable to salinization problems due to it is inserted in a semi-arid area. This study aimed to evaluate the biometrics, physiological, production and quality of new cantaloupe melon hybrids cultivated with different saline waters under semi-arid conditions. The experiment was conducted using a drip irrigation system in a split-plot randomized design. The plot was different irrigation water electrical conductivity (ECw) levels: 0.5, 2.0, 3.5, and 5.0 dS m-1, while the subplot was two new cantaloupe melon hybrids: Zielo and SV1044. Plant biometrics (stems and leaves analysis), plant physiology (solutes accumulation and gas exchange in leaves), fruit production (number, weight, and yield), and fruit quality (physical and chemical analysis) were investigated. Stem length, leaf numbers, leaf area, and shoot dry mass decreased when ECw increased from 0.5 to 5.0 dS m-1. Also, there was an increase of Na and Cl concentration and reduction of K concentration in leaves due to ECw increase. Gas exchange reduction, losses in fruit numbers, weight, yield, and in quality were observed with the ECw increase. It is possible to conclude that the ECw increase salinizes the soil and increases Na and Cl concentration in plants causing reduction in gas exchange, in growth, and in fruit production and quality. However, the response of cultivated hybrids regarding salinity may be different, as in our study that the Zielo hybrid was less affected by the increase in ECw.Brazilian Northeast region emerges as both producer and exporter relevant of cantaloupe melon to several countries; however, this region is vulnerable to salinization problems due to it is inserted in a semi-arid area.

Chickpea production in response to fertilization with zinc and doses of phosphorus
Get PDFChickpea cultivation in Brazil has not yet been consolidated, and studies aiming at the adequate nutritional management for this crop are necessary. This work aimed to evaluate the production of chickpea plants (cultivar BRS Aleppo) subjected to fertilization with zinc and P doses. The experimental was completely randomized, with four replications, in a 3 x 5 factorial scheme, corresponding to three fertilization treatments with Zn (without Zn addition; 50% of Zn applied at sowing, via soil + 50% applied at flowering, via leaves; and 100% applied at sowing, via soil) and five doses of phosphorus (0, 60, 120, 180, and 240 kg ha-1 of P2O5). The 100-grain mass (M100), pod mass (MV), number of pods (NV), number of grains (NG), total grain mass (MGT), yield (PROD), dry matter of the shoot part (MSPA) and plant residues (MSRV), and agronomic efficiency (EA) were characterized. There was an isolated effect of the P doses on the M100, MGT, PROD, MSPA, and MSRV characteristics. The application of 240 kg ha-1 resulted in an increase in the production components and a maximum yield of 3,018 kg ha-1, indicating the need to adopt higher doses of P2O5 to increase chickpea production in tropical soils. However, the highest agronomic efficiency was obtained after the application of 60 kg ha-1 of P2O5, along with Zn at sowing.Chickpea cultivation in Brazil has not yet been consolidated, and studies aiming at the adequate nutritional management for this crop are necessary.

Growth and nutritional diagnosis of Rosemary plants submitted to nitrogen and sulfate fertilization
Get PDFStudies on the cultivation of medicinal plants are of relevance to the population since they are primary sources of medication. Among these plants stands out the rosemary (Rosmarinus officinalis L.) for having diverse therapeutic properties. The objective of this work was to evaluate the initial growth and nutritional status of rosemary plants grown with different co’ncentrations of nitrogen and sulfur. The treatments were distributed in a 4x2 factorial scheme with four nitrogen doses: 105, 210, 315, and 420 mg L-1 of nitrogen combined with two sulfur doses: 32 and 64 mg L-1 with seven replications totaling 56 experimental units. The seedlings were obtained through asexual propagation (cuttings), originating from parent plants. The experimental units were arranged in a completely randomized design. Growth evaluations were carried out at 120 days of cultivation, using: plant height (HT) stem diameter (DS), root dry matter mass (RDM), stem dry matter mass (SDM), mass leaf dry matter (LDM), total dry matter (TDM), shoot dry matter mass (SDMS). The data obtained were subjected to analysis of variance and depending on the level of significance in the F test, the study was carried out using the means test (Tukey 5%). The agronomic characteristics (HT), (DS), (RDM) and (MDMAP) were significant for N. Only (RDM) showed significant interaction for the doses of N and S. The dose 420 mg L-1 promoted the highest concentrations in the components leaf and stem. The lowest dose 105 mg L-1, N promoted the highest concentrations of S in the leaf and stem. The assimilation of S by the rosemary plants was dependent on the doses of N.Studies on the cultivation of medicinal plants are of relevance to the population since they are primary sources of medication.

Cymbopogon citratus essential oil has hepato/renal protection and anti-genotoxicity against carbon tetrachloride
No full textNowadays, there is an increasing trend to use aromatherapy for treatment of various diseases. Cymbopogon citratus (Lemongrass) is one of many plants which have been reported to employ successfully in aromatherapy. Herein we decided to explore the protective role of Cymbopogon citratus essential oil (CCEO) against hepato/renal damage and genotoxicity induced by carbon tetrachloride (CCl4) and the relation of this bioactivity with its chemical constituents. Six main groups of mice (five/each) were examined: I- represents negative control group, II and III- mice received oral treatment with CCl4 (1mL/kg, positive control) and CCEO (0.3 mL/kg, control plant) respectively for five consecutive days and IV-VI- represent groups of mice treated with CCEO at the three concentrations 0.1, 0.2, 0.3 mL/kg plus CCl4 (five consecutive days treatment). Remarkable adverse effects of CCl4 in all the tested parameters were recorded. These effects were distinguished as an increment in the level of all liver marker enzymes (ALT, AST, ALP, γ-GT), blood urea, and creatinine. Also the oxidative stress biomarkers: malondialdehyde (MDA) and glutathione-transferase GST were affected after CCl4 treatment. Regarding to the genotoxic effect of CCl4, the percentage of chromosomal aberrations in bone marrow and spermatocyte cells was elevated (p< 0.05) compared with the negative control. Notable antioxidant, hepato/renal protection and anti-mutagenic potency of CCEO against CCl4 were demonstrated with a dose-related relationship. GC/MS analysis demonstrated the presence of 12 phytochemical constituents which in combination play a critical role in its antioxidant/antigenotoxic efficacy. The major components exist were E. Citral (35.13%) and Geraniol (32.83%).(five consecutive days treatment). Remarkable adverse effects of CCl4 in all the tested parameters were recorded.

Light quality on growth and phenolic compounds accumulation in Moringa oleifera L. grown in vitro
Get PDFAll plant parts of the Moringa oleifera can contain relevant concentrations of phytochemicals with health benefits. Plants grown in vitro allow pathogen-free plant material production and rapid propagation, and this technique is widely used to obtain secondary metabolites. This study analyzed how light spectrum quality affects growth, chlorophyll, and total phenolic content in M. oleifera plants grown in vitro. M. oleifera seeds were inoculated in MS medium supplemented with 3% sucrose and 0.7% agar and were stored under a controlled temperature, humidity and photoperiod. The light conditions tested were white fluorescent lamps (WFL) and light-emitting diodes (LED: 70% red + 30% blue), both standardized with a photon flux density of 58 μmol m-2s-1. Radiation emitted by WFL and LED did not influence stem germination, height, or diameter. However, WFL provided higher total chlorophyll levels. All plant parts germinated in vitro were analyzed via high-performance liquid chromatography with a diode-array detector (HPLC-DAD), and preliminary analyses revealed preferential synthesis of gallic acid derivatives in the leaves under LED radiation. For the total phenolic content, leaves under the LED and WFL irradiations showed 3.524 ± 0.054 and 3.805 ± 0.304 micrograms, respectively, of gallic acid equivalents per milligram of dry matter (μg GAE mg-1 DM). Light quality did not interfere with phenolic compound accumulation; however, it stimulated the preferential synthesis of gallic acid derivatives in leaves grown under LED radiation, and the evidence indicated that all evaluated organs synthesized nonpolar substances.All plant parts of the Moringa oleifera can contain relevant concentrations of phytochemicals with health benefits.

Biofertilizer in leaf and drip applications: an alternative to increase tomato productivity
Get PDFThe tomato is a species of undetermined growth and extremely demanding in nutrients Therefore, the search of new ways to maximize the use and supply of fertilizers sources and their application mechanisms are important to improve the tomato culture management. The aim of this study was to evaluate the application methods of liquid biofertilizer (BF) and the harvest times throughout cultivation. The experiment was carried out in a randomized block design, in a 3x6 factorial with subdivided plot and seven replications. The treatments were foliar and drip BF application and a control, without application of BF, and harvesting time (85; 92; 99; 106; 113; 120 days after transplanting-DAT). Leaf application resulted in a class I production increase in the second week of harvest (92 DAT), while drip application reflected higher class II and III production in the fourth week (106 DAT). In all treatments, at 92 DAT higher production of large fruits (class I) was observed. Production of average fruits (class II) occurred at 92 and 113 DAT and small fruit (class III) production was concentrated at 113 DAT. The adoption of BF, regardless of the application form, provides an increase in total productivity, with an income up to 35% higher. Therefore, biofertilizer is a good source for nutrition implementation aiming at yields and returns in the tomato production chain.The tomato is a species of undetermined growth and extremely demanding in nutrients Therefore, the search of new ways to maximize the use and supply of fertilizers sources and their application mechanisms are important to improve the tomato culture management.

Agronomic characterization of citrandarin fruits and seeds
Get PDFIn citrus cultivation, rootstocks are of fundamental importance and affect several characteristics of the variety used as canopy. Despite the great diversity within Citrus and related genera, the production of rootstocks in Brazil is restricted to a small number of varieties, making the citrus culture vulnerable to the appearance of phytosanitary problems. The aim of this study was to agronomically characterize fruits and seeds of seven citrandarins [Citrus sunki (Hayata) hort. ex Tanaka x Poncirus trifoliata cv. Rubidoux (L.) Raf.], obtained by controlled crossing. The orchard was installed in randomized blocks, with three replicates, in the municipality of Cordeirópolis, SP, where 20 fruits were collected in each replicate, obtained from free pollination of seven citrandarins, Swingle citrumelo and Rangpur lime. The following variables were evaluated: fruit mass, height, diameter, total number of seeds and percentage of viable seeds per fruit; number of embryos per seed, mass of one thousand seeds, number of seeds in 1.0 kg, final emergence rate, number of seedlings per seed, polyembryony rate, emergence speed index and seedling height at 60 days after sowing. For fruit size, the highest values were obtained for Swingle citrumelo. For number of embryos per seed, seedlings obtained through seed and polyembryony, citrandarin TSxPT 245 showed the highest values. Although citrandarin fruits had smaller size than fruits from commercial Rangpur lime and Swingle citrumelo rootstocks, characteristics related to seeds such as viability, polyembryony and emergence rate, were similar or superior, and can be considered potential new rootstocks for the production of citrus plants.In citrus cultivation, rootstocks are of fundamental importance and affect several characteristics of the variety used as canopy.
