Knowledge on the ideal conditions for the formation of high quality seedlings is fundamental to guarantee establishment success of crops in a safe and efficient manner. Here, we evaluate the effect of different substrates and irrigation frequencies on the initial growth of parica (Schizolobium parahyba var. amazonicum) seedlings. The experiment was conducted in a greenhouse at the Federal Rural University of Amazônia, Capitão Poço, PA. Several variables were analyzed including seedling height, stem diameter, number of leaflets, shoot dry matter, root dry matter, total dry matter, height and stem diameter ratio, shoot dry matter ratio and root dry matter. We found significant differences in seedling development between the applied treatments, including a significant interaction between substrate type and irrigation regime on seedling height, stem diameter, the number of leaflets and plant growth indices, with the best response for proportions 75% soil + 25% bovine manure and 50% soil + 50% bovine manure. Therefore, the substrates containing organic compounds resulted in a higher quality of the seedlings, while the sand consistently presented the lowest increases in seedling production under the three experimental irrigation frequencies, and thus is not recommended as a substrate for the development of Schizolobium parahyba var. amazonicum.

“…Contudo, o crescimento e desenvolvimento inicial é lento e desuniforme (Gatti, 2002;MoraesNeto et al, 2003;Tauchen et al, 2011), com velocidade positivamente relacionada à dureza da madeira Montes et al, 2008). As mudas requerem entre 6 e 8 meses para ser disponibilizadas para o plantio em local definitivo (Maranho, 2013). Devido a este comportamento de desenvolvimento (lento) há dificuldades de produção de mudas a partir de sementes, ainda que haja grande disseminação destas pelo vento (Gatti, 2002).…”

“…Isto porque esta madeira, com elevada flexibilidade e facilidade para secagem ao ar, possui resistência moderada à deterioração, além de apresentar características que a enquadram como de boa manipulação (serragem, aplainagem, faqueagem, desenrolagem, torneagem, colagem, parafusagem e pregagem), evernizagem, pintura e emassamento (Guitton, 1991;Lorenzi, 1998;Ugarte-Guerra & Domínguez-Torrejón, 2010). Pela baixa exigência em fertilidade dos solos, C. spruceanum também costuma ser empregada em plantios de áreas ciliares degradadas (Lorenzi, 1998;Maranho et al, 2013), sendo considerada uma boa alternativa para a recuperação deste tipo de área (Maranho et al, 2013).…”

que o ambiente amazônico se torne alvo constante da biopirataria e da extração predatória dos recursos. Muitas espécies deste ambiente sequer possuem catalogação e, mesmo assim, encontram risco eminente de desaparecimento. Neste âmbito, trabalhos que reúnam dados sobre estas espécies possuem grande valor científico, cultural e econômico, sendo este o estímulo que desencadeou a produção desta revisão. Aqui a espécie Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum., uma Rubiaceae amazônica, é contemplada por meio de características botânicas, indicações etnofarmacológicas e propriedades químicas. Popularmente conhecida como mulateiro, a espécie é frequentemente receitada na etnomedicina como cicatrizante e rejuvenescedor, além de ser usada no controle de manchas de pele. Como peculiaridade botânica, mulateiro apresenta tronco retilíneo com epiderme fina esverdeada que evolui para uma periderme castanho-escuro, que é anualmente renovada. Em termos químicos, há destaque para a presença de alcalóides, taninos e, sobretudo, secoiridóides (7-metoxididerrosideo, 6´-acetil-β-D-glucopiranosildiderrosideo e 8-0-tigloildiderrosideo são peculiares à espécie). Mesmo com propriedades fotoprotetoras comprovadas, C. spruceanum ainda carece de pesquisas, sobretudo àquelas voltadas para a produção ex situ da planta e àquelas que demonstrem a relação entre a ecologia da planta e a produção de metabólitos funcionais para a indústria. Palavras-chaves:Rubiaceae, mulateiro, extração predatória.ABSTRACT: On the botany, ethnopharmacology, and chemistry of Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum. The Amazonian environment is a constant target for biopiracy and predatory extraction of resources due to the species with vast economic potential. Many of these species have not even been cataloged, and yet are already at imminent risk of extinction. In this paper, Calycophyllum spruceanum (Benth.) Hook. f. ex k. Schum., an Amazonian Rubiaceae, is studied with information on its botanical characteristics, ethnopharmacological uses, and chemical properties. Popularly known as mulateiro, the species is often prescribed in ethnomedicine for healing and vitality, and is also used to control skin patches. As a botanical peculiarity, it has a thin green epidermis that evolves into a dark brown periderm, which is renewed annually. In terms of chemistry, there is emphasis on the presence of alkaloids, tannins, and, especially, secoiridoids (7-methoxydiderroside, 6′-acetyl-β-D-glucopyranosyldiderroside, and 8-O-tigloyldiderroside are peculiar to the species). Even with proven photoprotective properties, research on C. spruceanum is still lacking, in particular studies aimed at the ex situ production of the plant and those that show the relationship between the plant's ecology and the production of functional metabolites for the industry.

“…The development of commercial plantings of native species depends on the knowledge of their reproductive process, which includes the formation of seeds, determination of the harvest period, definition of extraction and processing methods, and determination of appropriate conditions for germination and storage (Alves, Sader, Bruno, & Alves, 2005;Pereira, Cuquel, & Panobianco, 2010;Maranho, Paiva, & Paula, 2013).…”

The objective was to study the processing of Vernonanthura discolor seeds, evaluating their physical and physiological qualities and defining parameters for purity analysis and determine the weight of one thousand seeds. The seeds extracted from the infructescences were processed in a blower, testing combinations of openings of the calibration valve and the side air passage. After processing, the seeds went through water content determination, germination tests, first count of the germination test, purity analysis, weight of one thousand seeds and percentage of full seeds. Compared to the control, seeds processed in a regulated blower with the calibrator valve in position 10 plus three 360° turns of side air passage obtained an approximately threefold increase in germination and vigour and had 96% purity. We conclude that the processing of V. discolor seeds was best done by combining the rubbing of the seeds on circular sieves (1.8 and 1.6 mm in diameter) and then passage in an adjusted seed blower (calibration valve in position 10 plus three 360° turns of side air passage). The weight of one thousand seeds is 0.500 g, and the working sample for purity analysis must be 1.3 g.
