title: Vegetative rescue of Camu-Camu from epicormic sprouts of detached branches

description: Abstract The cloning of camu-camu by cuttings has shown distinct and sometimes controversial results. The use of juvenile materials has been indicated for difficult rooting species. Thus, this work aimed to evaluate the emission of epicormic sprouts in mega-cuttings and cuttings of detached branches, as well as the cloning of camu-camu from these sprouts. The research was developed by conducting four experiments, the first two being related to the emission of epicormic sprouts, while the others referred to the cloning of camu-camu from these sprouts. In experiments evaluating sprout emission, the following factors were studied: mother plant x branch position; mother plant x substrate. In the other tests, using standard cuttings with two pairs of leaves made from epicormic sprouts, the following factors were evaluated: mother plant x cutting type x indolbutyric acid concentration (IBA); mother plant x hydroretentive polymer x environment. The number and speed of sprouts vary depending on the mother plant. IBA has negative influence on cutting and cuttings from the lower portion of sprouts have greater rooting potential than those from the upper portion. Environment with intermittent mist irrigation is more suitable for the propagation of camu-camu by cuttings. Vegetative rescue by means of epicormic sprouts in mega-cuttings and cuttings of detached branches presents potential application for the clonal propagation of camu-camu, requiring improvement in order to increase efficiency.

title: Evidence of maternal effect on germination and vigor of sour passion fruit

description: Abstract The seminiferous propagation of Sour Passion Fruit (Passiflora edulis Sims) is the main kind of multiplication due to the ease formation of seedlings. However, the reduced number of productive and homogeneous cultivars reflects the need for genetic breeding. The objective of this study was to assess the maternal and reciprocal effects in vigor and germination of Sour Passion Fruit seeds. The experiment was conducted in a completely randomized design in the factorial scheme, with two structure (hybrid and reciprocal) and ten crosses with four replicates (50 seeds) in trays containing inert sand in germination chamber. Before sowing, it was obtained the weight of 100 seeds, and at 28 days germination percentage, emergence speed index, total seedlings length, shoot length and main root length, number of normal seedlings and dry mass per seedlings were evaluated. The reciprocal effects tell us which genotype is most promising when used as the female or male parent for the trait studied. It can be inferred that there is maternal effect influencing the weight of 100 seeds, emergence, emergence speed index and the number of normal seedlings. There was influence of the parent on the expression of traits in seeds of Sour Passion Fruit. It is important to define the paternal and maternal parent to obtain seeds with high germination potential.

title: Propagation and initial development in lychee plants

description: Abstract The objective was to evaluate different methods of propagation and initial development of the lychee according to the place of production. The propagation methods were the Forking in seedlings produced in São João de Petrópolis-Santa Teresa and Air Layering in São João de Petrópolis, Santa Teresa-HQ, Colatina and Santa Maria de Jetibá. Each treatment consisted of 50 plants, and the percentage of graft catch, grape pick and transplant to the field was evaluated after three months. The seedlings produced in the different propagation sites were planted in the production field, with a spacing of 5x5 meters, being used as each treatment, 10 seedlings propagated in different places by Air Layering and propagation by forking. The propagation by Air Layering showed a better rate of catch than in grafting by Forking, however the Forking maintained 100% maintenance of the seedlings alive after the harvest. The treatments represented by the Air Layering in Colatina and São João showed the best results, showing that the spreading by Air Layering presents superior results when we use for the propagation, plants produced in places with similar characteristics to the planting site. Propagation by Air Layering is the best method of propagating lychee seedlings. Alporques propagated in the same region where the seedlings produced are definitively planted have greater adaptability and better development in the production field.

title: Partitioning of macronutrients and nutritional efficiency in fertigated prata banana

description: Abstract Adequate nutritional management of any plant species requires quantifying the nutrients accumulated in the plant and knowing their allocation in the different organs. The objective of this study was to evaluate the partitioning, accumulation, export of macronutrients and the nutritional efficiency of fertigated Prata banana plants. A historical survey of annual fruit productivity was conducted in 66 plots of Prata banana, selecting four that met the annual productivity classes (&lt; 30.0; 30.0 = 37.5; 37.5 = 45.0 and &gt; 45.0 t ha-1). The dry matter weights of the different organs of parent plant and follower, as well as the respective contents of macronutrients, were used to estimate the accumulation, partitioning, export, sequence of accumulation of macronutrients and nutritional efficiency using the coefficient of biological utilization (CBU). The partitioning of macronutrient accumulation varied with productivity class and plant organ. The average distribution of nutrients in the parent plant and in the follower ranged from 67.5 to 82.8 % and from 17.2 to 32.5 %, respectively. Macronutrient exports per ton of bunch were 4.334, 1.660, 0.361, 0.224, 0.148 and 0.119 kg t-1 for K, N, P, Mg, S and Ca, respectively. Banana mats have a nutrient partitioning pattern for different yields, that is, this work provides evidence that there is an “ideal compartmentalization” that promotes higher productivity; however, more research is needed to support this statement. The most exported nutrients per ton of bunch were K and N. The descending order of accumulation was: K &gt; N &gt; Ca &gt; Mg &gt; P &gt; S. It was observed that the CBUs of N and P were less sensitive to productivity variations, while those of Ca and Mg were the most sensitive.

title: Leaf area estimation of Anacardium humile

description: Abstract The Anacardium humile A. St.- Hil. fruit tree has productive potential, being their fruits appreciated in the Cerrado region for having characteristic flavor, however, this species is still exploited in an extractive way, being necessary studies for its domestication. The aim of this work was to estimate the leaf area of Anacardium humile. One hundred leaves were collected in the biological collection from a genetic resources field and evaluated for length, width and fresh weight, and scanned at resolution of 300 dpi to determine the leaf area with the aid of the ImageJ image analysis program. Subsequently, a leaf disc with a diameter of 22.27 mm was detached at the basal portion of each leaf, in which the fresh weight of the discs was obtained. Data were submitted to descriptive analysis and the relationship among the features explained by Pearson’s correlation with the software Rbio. The data were also subjected to regression analysis to explain the relationship between leaf area and measurements of width, length and leaf weight, and to fit the proper statistical model with the software Origin. It was concluded that leaf area can be determined by image analysis software and linear measurements are correlated to leaf area.

title: Vitis Labrusca L. grapes cultivars under hydric stress in protected cultivation

description: Abstract The expansion of the Brazilian wine border, combined with the development of new cultivars adapted to different regions, highlight the need for more information on irrigation handling for new cultivars in protected cultivation. Therefore, this study aimed to evaluate grapevine cultivars submitted to different percentages of water replacement in the soil in conditions of the Southern region of Minas Gerais with the use of irrigation. The experiment was installed and developed from 2014 to 2016. The experimental design used was random blocks, with five replicates and the treatments were disposed in subdivided plots, with three replacement percentages (30, 50 and 100 % of necessary water replacement for this type of soil) and in the subplots four grapevine cultivars belonging to Vitis labrusca L species. (‘Isabel’, ‘Isabel Precoce’, ‘BRS-Cora’ and ‘BRS-Violeta’). The research concluded that these cultivars increased 75 % the bunch length, 71 % of the bunch weight, 39 % the production of bunch of grapes, 52 % the pH, 84 % the soluble solid content and 60 % the reduction of total acidity content, 60 % to 100 % of water replacement. ‘Isabel precoce’ cultivar in water deficit conditions obtained the best productive results.

title: Pequi Kernel oil extraction by hydraulic pressing and its characterization

description: Abstract The seed by-products of pequi pulp processing have a kernel in its core which is not used due to the difficulty of its extraction from the spinous endocarp. However, this kernel has high quality oil which can be used for human consumption. Thus, the kernel and the oil composition as well as the conditions to obtain the kernel oil by hydraulic pressing were evaluated in this study. The kernel showed high lipid content (55.76%), therefore being a good source for obtaining oil. The oil extraction by hydraulic pressing presented a higher yield at 5.5 tons to 6.0 tons of force and 9% to 10% moisture. Oil recovery was 75%. The pequi kernel oil showed low acid (0.17 mg KOH/g) and peroxide (1.22 mEq O2/kg) values. The kernel oil also presented high levels of oleic acid (42.47%). The results indicate that the kernel oil extraction is an alternative form for using seeds to increase the producer/processor income and to decrease residue volumes in the pequi processing industry.

title: Canopy replacement used in the evaluation of cupuassu tree genotypes in the state of Pará

description: Abstract This study aimed to use the canopy replacement technique to reduce the field evaluation time and to select promising cupuassu tree clones. The study was carried out under field conditions using fifteen-year-old trees. The crowns were replaced using 16 treatments (clones). The experiment was conducted using randomized blocks design with 18 replicates and one plant per plot, during a period of ten years. The following variables were evaluated: average number of fruits, fruit, seed and pulp production (kg/plant) and symptoms of “witches broom” disease. The data were checked for normality followed by analysis of variance. The results highlighted clones 32, 42, 44, 46, 47, 61, 62, 63 and 64, presenting characteristics such as productivity, tolerance to witches’ broom disease and interesting fruit characteristics. The results demonstrate that the technique was effective in the evaluation of cupuassu tree genotypes, since the clones revealed their potential at early stages after establishment in the field. There was a reduction by at least 30% regarding the time needed to evaluate cupuassu tree genotypes. Five clones (32, 42, 46, 61 and 64) already present the potential to be made available to producers, aimed at replacing the canopy of unproductive trees.

title: Tipping off pruning and use of biofertilizer in the growth of pecan trees

description: Abstract In Brazil, the cultivation of pecan trees has substantially increased in the last years, thus requiring the development of scientific research and technologies to improve it. Thus, the aim of this study was to evaluate the tipping off effect associated with the use of biofertilizer in the growth of newly implanted plants in their final site. The treatments consisted of : control; application of “supermagro” biofertilizer; tipping off of plants, and tipping off associated with the use of biofertilizer. The variables evaluated were: plant height; plant growth rate; stem thickness; number of leaves, and number of leaves/stem height ratio. In addition, leaf nutrient content analysis was performed. Tipping off and the use of biofertilizer provide greater growth of the plant height and cultivar scion diameter after sprouting. Thus, tipping off associated with biofertilizer can be used in the early phase of the pecan orchard implantation to provide the best plant development.
