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.

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.

Introduction. Long-term genetic improvement efforts in Latin America aimed to ameliorate peach-palm fruit farmers’ technical capacities and livelihoods have proven to be ineffective. Although experts agree this is partly the result of large uncertainty regarding consumer preferences, such research remains as virtually nonexistent. Objective. To identify chemical and morphologic attributes that are attractive for final consumers of peach-palm fruit and how these attributes are related to final perceptions of fruit quality, through statistical and econometric methods. Materials and methods. By using the harvest from a large set of varieties from a peach-palm (Bactris gasipaes) germplasm bank in Southwestern Colombia, 482 evaluations were made between April to October of 2016 by local consumers who tasted the fruits and gave a report on their perception of taste/quality in a case study scheme. Combining these data with further information on fruit color, oiliness perception, and additional controls, an ordered logit regression model was set to identify the attributes that describe peach-palm fruits with the most favorable scores for their taste/quality perception. Results. Preferences on oil contents were not linear. Fruits perceived as high-oil were between 9 and 13 % more likely to be considered as having the best taste/quality, while those perceived high-starch content were correlated with a significant aversion towards the fruit, namely 43 % less likely to be among the best fruits. Conclusion. A great deal of research is yet to be done around peach-palm fruit consumer preferences and, furthermore, it should be carried on an interdisciplinary ground. Further analyses of desired fruit traits should be made at sub-national levels, identifying ranges of suitable oiliness and morphological expected attributes and how available genetic material could help to satisfy those needs.

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.
