Superior Genotypes

The peach palm (Bactris gasipaes) is a native Amazonian palm tree that produces fruits and palm hearts, and is now attracting the interest of the farmers in other parts of Brazil given the economical potential of palm heart production. Traditionally the peach palm is propagated by seeds, which yield segregating progenies due to cross-pollination. To guarantee the uniformity and quality of elite selections, the alternative is the propagation of superior genotypes from off-shoots (tillers), because an efficient in vitro cultivation protocol does not exist. The objective of the present study was the development of a more appropriate technique of vegetative propagation by division of the clump, in order to multiply plants selected in the improvement program. A peach palm clump contains between 2 and 20 off-shoots after cutting for palm heart; these can be separated one from the other with iron wedges, and extracted immediately or left for recovery for subsequent extraction. The experimental design was randomized blocks with three replications, using a 3x5 factorial, where the factors were: height of the off-shoots (<30, 30-60, >60 cm) and recovery time after the separation of the off-shoots from the clump (0, 30, 60, 90 and 120 days). The off-shoots between 30 and 60 cm and left around a month of recovery in the field after separation from the clump presented 65% of survival, while those left around four months presented 80% of survival.

Aim. To evaluate the activity of cryopreserved boar ejaculated spermatozoa under different thawing protocols to optimize biotechnological approaches in pig reproduction based on the genetic material of the Institute of Animal Breeding and Genetics nd. a. M.V. Zubets of National Academy of Agrarian Science of Ukraine. Methods. Cryopreserved ejaculated boars' sperm was thawed in three different ways. Biotechnological, cryobiological and morphological methods were used to assess the viability of the sperm. Results. We noted the individual feature of semen quality of the studied boars, which affects its suitability for cryopreservation and quality indicators after thawing. It was found that in liquefied boar sperm (sperm activity on average is 86.7%) after its centrifugation and three-hour equilibration at + 4 °C sperm activity decreased by an average of 25.0%. In order to improve the quality of cryopreserved sperm, it was thawed under different conditions. The highest activity of spermatozoa in thawed sperm of boar No. 225 of Myrhorod pig was at the level of 25.0% at the thawing temperature + 70 °C, and the thermal resistance and heat resistance were 70.0% and 60.0%, respectively. Conclusions. During this study was noted that there are peculiarities of boar semen at breed and individual level, which influence its ability to tolerate cryopreservation.

Ilha Solteira, SP4Departamento de Biologia e Zootecnia, Faculdade de Engenharia, Universidade Estadual Paulista. Ilha Solteira, SP  1 RESUMO           A cultura da pupunha, além de cultivada principalmente para a produção de palmito, também produz matéria verde que pode ser utilizada na alimentação animal, reduzindo assim os custos de produção. Estes resíduos, oriundos do processamento do palmito, são constituídos por folhas, bainhas e partes do estipe, podendo ser fornecido na forma de feno ou silagem aos animais. Todavia, a exploração economicamente viável desta palmeira no noroeste paulista somente é possível com o uso de irrigação. Por conseguinte, estudos foram realizados com o objetivo de se identificar a lâmina de irrigação para a cultura, quantificando seus efeitos na produção deste subproduto da produção de palmito. Para tanto, o experimento contou com 6 tratamentos compostos por lâminas de irrigação, cada um com 4 repetições, onde as lâminas aplicadas variaram desde sem irrigação até reposição de 150% da evaporação do Tanque Classe A (ECA). Os resultados obtidos neste trabalho indicaram que a reposição de 75% da ECA no primeiro ano de produção resultou na melhor lâmina, enquanto que no segundo, a melhor foi obtida repondo-se 100% da ECA, com uma produtividade respectivamente de 74,55 e 114,94 toneladas de resíduos por hectare, demonstrando o grande potencial da cultura para produzir matéria verde, sob manejo adequado da irrigação. UNITERMOS: nutrição animal; manejo da irrigação; Bactris gasipaes H.B.K.  ALVES JUNIOR, J.; LOPES, A. da. S.; HERNANDEZ, F. B. T.; SANTOS, R. A. dos.; BERGAMASCHINE, A. F.; GREEN MATTER PRODUCTION IN IRRIGATED PEJIBAYE   2 ABSTRACT           Pejibaye, besides being cultivated mainly to palm heart production, also produces green matter that can be used in animal feeding, lowers production costs. These by-products, originated from the palm heart processing consisted of leaves, hems and plant parts and could be used as hay or silage to animals. However, the economically viable exploration of this palm tree in the northwest of São Paulo is only possible with the use of irrigation. Consequently, studies were carried out to identify the best irrigation level to culture, quantifying their effects on this palm heart by-product production. Therefore, the experiment had 6 irrigation level treatments, each one with 4 replications, in which the applied levels varied from without irrigation to 150% evaporation replacement of a Class A Pan (ECA). The results obtained in this work indicated that the replacement of 75% of ECA in the first year of production resulted in the best level, while in the second one, the best level was obtained from 100% of ECA, a respective productivity of 74.55 and 114.94 tons of residues per hectare, showing the great potential of the culture to produce green matter, under appropriate irrigation management. KEYWORDS: animal nutrition, irrigation management, Bactris gasipaes, H.B.K.

ABSTRACT: The peach palm (Bactris gasipaes) is a palm tree that produces palm heart originated of Amazonia with economic, social and environmental sustainability. To obtain improved cultivars it is necessary the evaluation and selection of genotypes with characteristics that support producers, manufacturing and consumers. In this context, the objective of this study was to estimate genetic parameters for palm heart production traits of peach palm considering half sibs progenies. Twenty progenies of Putumayo macrocarpa race were evaluated in seven cultivation cycles. The experiment was designed in complete randomized blocks, with 40 repetitions and one plant per plot. The genetic parameters were estimated by REML/BLUP methodology. Low genetic variability was observed in the population, possibly due to the narrow genetic base from original population. However, considering the significant genetic effect and the progeny mean heritability, the selection performed between progenies is more efficient than individual selection. The high number of measurements required for most of the evaluated characters becomes impractical in peach palm breeding programs. The number of palm heart per plant can be used to perform indirect selection for total production of palm heart.

The Southern Caracara (Caracara plancus) is a South American falconid that over the years has been colonizing open areas of the Southwestern Amazon. Regarding food habits, it is considered an opportunistic/generalist species. Caracara plancus has a varied diet, composed of animal protein, including carcasses. It also consumes plants, although this behavior appears less frequently in the scientific literature. Here we present a report of a Southern Caracara feeding on peach-palm fruits (Bactris gasipaes) in the rural area of Brasiléia, state of Acre, Brazil. The peach-palm tree is a common species, cultivated for obtaining heart of palm (“palmitos”) and fruits for consumption and regional marketing. Besides being a new food item in the Southern Caracara diet, the observed behavior indicates that C. plancus can potentially become a plague to the regional culture of peach-palm.

Bactris gasipaes Kunth (peach palm) is a palm tree (Arecaceae) widely used by Amazon people, whose seeds have dormancy of unknown cause, which result in difficulties on producing uniform seedlings. This study aimed at identifying anatomical and histochemical aspects of peach palm seeds that may have influence on germination. Histological sections were performed with seed material embedded into hystoresin, which were then stained with toluidine blue and assessed under optical microscope to verify structural characteristics. Histological sections were manually performed to identify primary and secondary metabolites; and histochemical test were performed for fatty acids, alkaloids, starch, phenolic compounds, lignin, neutral and acidic lipids, pectins, polysaccharides, proteins, tannins, and terpenoids. Tegument is thin and contains two layers. The external layer is thicker and has vascular bundles; and the internal layer is thinner containing irregular cells replete of phenolic compounds. Endosperm is whitish in color, with cells with shapes that vary from oblong or ellipsoidal until oval; containing lipids, proteins, pectins, and polysaccharides. Embryo is relatively small as related to seed size, conical and vascularized at distal portion. On longitudinal sections, plumule appears in proximal region as three foliar primordia. At seedling protrusion region the cells contain acidic lipids, proteins, and neutral polysaccharides.

The climatic influence in minerals content of peach palm heart (Bactris gasipaes Kunth) was studied and a quick method was assessed to determine Mg, Cl, K and S in the basal portion of peach palm heart based on multivariate predictive model using agro-meteorological data. A total of 24 samples of B. gasipaes Kunth were collected along 14 to 18 months of cultivation, growing in two types of terrain: hillside and lowland. Principal component analysis (PCA) was used to select principal components. The data were modeled using partial least squares regression (PLS). Low average relative prediction errors (4.60%) confirm the good predictability of the models. The factors that most influence the minerals content prediction model were the rain precipitation and solar radiation. The results show that predictive model can be used as rapid method to determine the mineral content in the basal portion of peach palm heart factories and may help to choose geographical regions suitable for the establishment of new peach palm plantations. The models can provide reductions of cost and time analysis to palm heart without generating laboratory effluents. This is the first time in which multivariate analysis is used to generate models to predict minerals concentration in the basal portion of peach palm hearts, quantifying numerically the intensity of climatic factors in the minerals content.
