A polinização da pereira europeia (pyrus communis L. cv. Rocha) no sul do Brasil
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Programa de Pós-Graduação em Recursos Genéticos Vegetais, Florianópolis, 2014No Brasil, a produção de pera é insuficiente para atender a demanda interna, gerando uma crescente necessidade de importação de frutas que podem ser produzidas nas regiões mais frias. Por isso, a pera é a fruta fresca importada em maior quantidade pelo Brasil. Por ser alógama devido à incompatibilidade gametofítica, a maioria das cultivares europeias de pereiras não produzem frutos com sementes sem a presença de insetos polinizadores. Neste contexto, foram realizados ensaios buscando elucidar os aspectos da biologia reprodutiva da pereira portuguesa (Pyrus communis L. cv. Rocha) e suas cultivares polinizadoras, assim como avaliar a qualidade das colmeias destinadas à polinização. Os resultados mostraram que a fenologia das cvs. Rocha e suas polinizadoras diferiu entre elas e entre os anos, podendo afetar significativamente a polinização. A data aproximada da plena floração das cultivares estudadas foi similar em 2012 (? 17//09), porém, diferiu em 2013. Foi observado que a cv. Rocha polinizada com pólen de cultivares compatíveis apresentou elevada frutificação efetiva, chegando a atingir até 67,8% de frutificação efetiva sem a aplicação exógena de giberelina. Além disso, nestes frutos observou-se maior número de sementes (>5 sementes.fruto-1), o que acarretou frutos com melhores índices de qualidade comparativamente com outros tratamentos de polinização. A autopolinização promoveu a formação de frutos (10,9% de frutificação efetiva em 2012 e 1,66% em 2013), mas em quantidade e qualidade inferiores aos frutos oriundos de polinização cruzada. A partenocarpia natural foi observada na cv. Rocha, mas esta incapaz de sustentar produções comercialmente viáveis (4,16% de frutificação efetiva). A aplicação exógena de ácido giberélico mostrou ser uma opção para o aumento da frutificação efetiva através do estímulo da formação de frutos partenocárpicos, contudo foi observada uma variação na sua eficiência entre os anos (frutificação efetiva de 74,1% em 2012, reduzindo para 30,0% no ano seguinte) e a tendência da redução da qualidade dos frutos formados, os quais eram menores e mais alongados do que os frutos com sementes. A produção de néctar variou entre cultivares e entre os anos, mas sendo sempre considerados volumes pequenos (Abstract: In Brazil, the pear production is insufficient to supply the domestic demand, creating a growing market for imported fruits that can be produced in south Brazil. Due to this, Brazil's fresh pear imports grow every year. Since pears are alogamous due to gametophytic incompatibility, most European pear cultivars do not produce fruit with seeds without the presence of pollinating insects. In this context, experiments were conducted to elucidate the aspects of the reproductive biology of the Portuguese pear (Pyrus communis L. cv. Rocha) and their pollinating cultivars, as well as the quality of the hives used for orchard pollination. The results show that the phenology of cvs. Rocha and their pollinators differs between them and years, which may significantly affect pollination. The approximate date of full bloom of the cultivars was similar in 2012 (~=17/09) while differ in 2013. We observed that cv. Rocha pollinated with pollen from compatible cultivars showed a high fruit set, reaching up to 67,8% of fruit set without exogenous gibberellin application. Moreover, in these fruits was observed a greater number of seeds (> 5 seeds.fruit-1), which resulted in higher quality fruits (scores compared with other pollination treatments). Self-pollination produced some fruits (10,9% of fruit set in 2012 and 1,66% in 2013), but in lower quantity and quality when compared with cross-pollination. Natural parthenocarpy was observed in cv. Rocha, but it was unable to sustain commercially viable yields (4,16% of fruit set). The exogenous gibberellic acid application was an option for increasing fruit set by stimulating the formation of parthenocarpic fruits, however we observed a variation of it's efficiency between years (fruit set of 74,1% in 2012, decreasing to 30,0% in 2013) and showed a trend of reduced quality of formed fruits, which were smaller and more elongated than the fruit with seeds produced by cross-pollination. Nectar production varied among cultivars and years, but always being considered small volumes (<3µL) and whith low sugar content (<20ºBrix), which resulted in low attractiveness of pollinators (<1 bee.tree-1.minute-1). In the surrounding area of the orchard we observed strong competition with Mimosa scabrella and Piptocarpha angustifolia wich bear more and richer nectar. We observed poor natural pollination due to the non-pollen deposition on the stigmas of 'Rocha' after a legitimate flower visit by Apis mellifera, possibly due to lack of pollinating plants and low density of quality beehives in the orchard. The hives used for pollination showed a variation in their population between years, wich can be observed in the significant reduction in the number of combs covered with larvae and honey reserves from 2012 to 2013, resulting in lower activity of foraging bees in the period of maximum flight activity (100,8 foraging bees entering in the hive.minute-1 in 2012 and 59,3 foraging bees entering in the hive.minute-1 in 2013). We also observed the presence of Varroa destructor (infestation of 1.89 and 1.45% in 2012 and 2013, respectively) and Nosema ceranae (712.000 spores.bee-1 in 2012)

Uso de pó de rocha em plantas forrageiras.
No full textOs fertilizantes e os corretivos agrícolas são os insumos mais importantes para o desenvolvimento das culturas e, portanto, para a produtividade. A maioria deles vem de fontes industriais e são solúveis, como o NPK (mistura de concentrações diferentes de nitrogênio, fósforo e potássio), contendo ou não micronutrientes. Diante de custos crescentes e maior preocupação ambiental, é preciso encontrar alternativas para correção da fertilidade e acidez do solo. Rochas moídas podem ser utilizadas para fertilizar o solo, num processo conhecido como rochagem, que fornece agrominerais (ou remineralizadores); estes são matérias-primas de origem mineral, como resíduos de mineração, garimpo e metalurgia, para aplicação em solos agrícolas. O uso de pó de rocha traz benefícios para o solo, como o aumento da capacidade de troca catiônica (CTC) e do pH, diminuição de alumínio trocável, fornecimento de macronutrientes (em especial o potássio) e micronutrientes, também contribuindo para melhorias em sua estrutura. É aplicado em olericultura, fruticultura, cana de açúcar, cereais, setor florestal e pastagens, em substituição e/ou complementação aos fertilizantes industrializados. Sua eficiência agronômica depende de fatores como a mineralogia, a composição química e a granulometria de rochas moídas, condições de clima e de solo e da atividade microbiana. Este Comunicado Técnico apresenta conceitos e resultados de pesquisas com pó de rocha em plantas forrageiras que vão ao encontro dos Objetivos do Desenvolvimento Sustentável (ODS) contidos na Agenda 2030, propostos pela Organização das Nações Unidas, da qual o Brasil é signatário, contribuindo para o alcance do ODS 2 ?Acabar com a fome, alcançar a segurança alimentar e melhoria da nutrição e promover a agricultura sustentável, coadunando com as Metas 2.3 e 2.4 (Produtividade de pequenos agricultores e Agricultura sustentável, respectivamente)

The tunic is leathery and rough with numerous organisms encrusting the brown or light brown surface (Fig. 15). The tunic is white inside and has a yellowish soft membrane. In the field, the siphons show four small triangular lobes, the oral siphon is usually apical and the atrial more lateral. There are long spines (~160 µm) lining both siphons with a very distinctive shape: narrow with a round enlargement in the middle and at the posterior extremity (Fig. 16C, D). Iridescent spots of blue, green or yellow color caused by the reflection of light by the enlarged areas of the spines are seen against a brown or reddish background (Fig. 15). After long fixation, the tunic turns light brown. Often, a tinge of red can still be seen around the siphons. The body wall has many longitudinal muscles radiating from the siphons; they form thin bands that cross each other making a musculature net. Circular muscles densely surround both siphons. The U-shaped right gonad and the enlarged secondary loop of the alimentary canal on the left side are visible through the transparent body wall (Fig. 16A, B). The tentacles project at the level of a strong muscular sphincter, the number ranging between 16–29. They are flat, very wide at the base and ramifying two or three times, with primary ramifications projecting along the posterior margin (Fig. 16E, F). The third order ramifications are minute and only appear in the largest tentacles that can reach 7 mm in length. The peritubercle region forms a deep V with the dorsal tubercle has U- or C-shaped aperture with enrolled ends. The dorsal lamina is divided in numerous thin and long densely packed languets. The pharynx has six folds per side and is orange when fresh (Fig. 16G), but quickly loses coloration after fixation. The number of longitudinal vessels range from 305 to 410. Longitudinal vessels fray toward the base of the animal, making languets around the esophageal opening. Parastigmatic vessels are present. Endocarps are present along the intestine, especially along the descending limb (Fig. 17B). Both gonads have large endocarps on each lobe, particularly the distal ones (Fig. 17C).

Ventral right gonad. 1 character variation includes information in Monniot (1994), 2 character variation includes information in Monniot (1983) and Monniot (2018); 3 character variation includes information in Tokioka (1972) The alimentary canal occupies 2/3 of the left side. The primary loop does not reach the peripharyngeal groove, forms a close curve with a vertical descending limb that forms another close second loop with the ascending rectum (Fig. 17A). The intestine is not isodiametric; the secondary loop and rectum are enlarged. The anus is lobed. The digestive gland is dark green and forms lobes connected by long tubes as in a cauliflower. It has two main connections to the stomach. On the left side, the gonad completely fill the space within the primary intestinal loop, the number of gonad lobes ranging from 30–47. The right side of the animal is occupied by a large characteristic Ushaped gonad with 26 to 42 gonadal lobes. The gonoducts are long, the oviduct slightly longer than the sperm duct, both opening at the level of the anus. Remarks. This is one of the most common species both in mangrove and reefs around Bocas del Toro province (Rocha et al. 2005) and also found in Colon region but it has not been found on a survey of the Pacific coast (Carman et al. 2011). The specimens from Panama agree well with the description of P. vittata from Guadeloupe and Martinique (Monniot, C. 1983; Monniot, F. 2018). We believe that P. vittata reported by F. Monniot (2016) from French Guiana is actually P. beta Skinner, Rocha & Counts, 2019.Published as part of Rocha, Rosana M. & Counts, Bailey Keegan, 2019, Pyura (Tunicata: Ascidiacea: Pyuridae) on the coasts of Panama, pp. 491-513 in Zootaxa 4564 (2) on pages 509-512, DOI: 10.11646/zootaxa.4564.2.9, http://zenodo.org/record/258940
ß-Farnesene exogenous application as a novel damage induction model to fast explore the effectiveness of postharvest strategies: the case study of the ‘Rocha’ pear DOP
No full textSince the prohibition of diphenylamine, replacement strategies have been needed for long-term disorder prevention, namely superficial scald (SC), in fruit. However, as this disorder only appears after months under cold storage, the assessment of effective strategies to prevent this disorder requires long periods. To tackle this challenge, we report in this paper a rapid and reliable system to induce symptoms, such as SC, based on storage under a β-farnesene-enriched atmosphere. Using this model, SC symptoms in ‘Rocha’ pear were induced after 15 d at 20◦ C. As proof of concept, this model system allowed the study of the efficiency of antioxidant natural-based coatings on ‘Rocha’ pear quality maintenance. Pears treated with the coatings were submitted to 4 months of commercial storage under normal atmosphere conditions and the results were compared with those obtained using the induction model system. A PCA of chemical data allowed us to conclude that the model developed simulates the potential of certain strategies to prevent disorders.info:eu-repo/semantics/publishedVersio

As in Ale-Rocha (2006), plus frons narrow (at mid-length narrower than width of anterior ocellus) (Fig. 14). Veins M 1 and M 4 reaching the wing margin (Fig. 50). Hind femur slightly clavate. Fore and mid tarsomeres 3– 4 and hind tarsomeres 3–5 ventrally with short, blunt, black spine-like setae. Type material examined. PARATYPES: Bolivia. La Paz, Chulumani, Apa-Apa, 16°22′S, 67°30′W, 1– 4.v.1997, 1800 m, L. Masner s.s. B-09 (7 ♂, INPA). Remarks. In the original description, a photo of the wing of C. masneri was presented (Ale-Rocha 2006, fig. 40), which highlighted the sinuosity near the apex of vein R 1 as diagnostic of the species. After re-examining the paratypes and a photo of the holotype, we noted that vein R 1 is not so sinuous near the apex and does not run closely to R 2+3 (Fig. 50) as previously described, indicating that the wing in Ale-Rocha (2006) does not belong to this species. Therefore, we provide here a new wing photograph of a male paratype. Geographical distribution. This species is known from Bolivia (La Paz) and Guatemala (Sacatepequez) (Fig. 53).Published as part of Barros, Luana Machado, Soares, Matheus Mickael Mota, Freitas-Silva, Rafael Augusto Pinheiro De & Ale-Rocha, Rosaly, 2019, Neotropical Chvalaea Papp & Földvári (Diptera: Hybotidae: Ocydromiinae): new records, an illustrated key to species and description of three new species, pp. 347-362 in Zootaxa 4571 (3) on pages 355-356, DOI: 10.11646/zootaxa.4571.3.3, http://zenodo.org/record/261270

Rafael, J.T. Câmara, R.F. Silva, A. Somavilla, C. Gonçalves, leg. (1 ♂, INPA). Distribution. Brazil (Amazonas and Roraima *) (Fig. 57). Variation. The female from Roraima has the base of the postpedicel yellow and the scutum pale brown, slightly darker than on the holotype. Remarks. This unusual species is probably the most autapomorphic in the genus, by the following set of characters: postpedicel very long, about 3 x longer than preceding segments combined (the longest for the genus up-to-date), prosternum fused to proepisternum, abdomen weakly sclerotized and epandrial lamella with 1 long dorsoapical projection, about half-length of lamella (Ale-Rocha & Vieira 2008, fig. 17). The prosternum is fused to the proepisternum forming a precoxal bridge that does not seem to be homologous to that of the other Brazilian species of Syneches: S. catarinae, S. curvipes, S. rafaeli and S. walkeri because in these latter species, the prosternum has a wide connection with the proepisternum (Fig. 2C), while in S. longiflagellatus these sclerites are connected by a narrow region.Published as part of Soares, Matheus M.
