“…The increase of dry mass in B. orellana seedlings -which was caused by the pre-soaking of seeds in a 12.0 mL L -1 Simulate ® solution for a period of eight hours -was also observed in a study conducted by Scalon et al (2009). The researchers found that the treatment of gabiroba (Campomanesia adamantium) seeds with Stimulate ® (0.2 mL L -1 ) caused a significant increase in their dry mass, 145 days after sowing, as opposed to the control.…”

The aim of this study was to assess the germination and vigor of Bixa orellana seeds that were pre-soaked in different concentrations of Stimulate ® plant biostimulant. For the standard germination test, Bixa orellana seeds from the Embrapa 37 Cultivar were pre-soaked (for periods of four and eight hours) in the following concentrations of Stimulate ® aqueous solution: 3.0; 6.0; 9.0; and 12.0 mL L -1 . Seeds that were pre-soaked in distilled water were used as control. The following parameters were tested: germination; first germination count; abnormal seedlings; length; and seedling dry mass. The experimental design was completely randomized and a 2 x 5 + 1 factorial design was used (with two pre-soaking periods, five Stimulate ® concentrations, and one additional control without pre-soaking). Four replicates of 50 seeds were performed for each treatment. Water immersion treatments for four and eight hours were efficient for breaking dormancy in Bixa orellana seeds, since they promoted better germination in relation to the intact seeds that were not pre-soaked. The presoaking of Bixa orellana seeds for eight hours in a 12.0 mL L -1 Stimulate ® concentration presented the best results in terms of germinative performance and seedling growth, with greater accumulation of dry mass. Therefore, this practice is recommended for the production of seedlings of this species.

“…Plant biostimulants may be used to accelerate and improve seed germination, and also to promote the growth of seedlings of several species (PRADO NETO et al, 2007;SCALON et al, 2009;KISSMANN et al, 2011;PIEREZAN et al, 2012).…”

A catingueira (Caesalpinia pyramidalis Tul.) é uma espécie florestal pertencente à família Caesalpiniaceae, considerada endêmica do bioma Caatinga. O objetivo do presente estudo foi avaliar o efeito da temperatura e do substrato na germinação de sementes de C. pyramidalis Tul. O delineamento experimental utilizado foi o inteiramente casualizado, num arranjo fatorial 5 x 4, perfazendo 20 tratamentos, constituídos pelas combinações de cinco temperaturas (25, 30, 35, 20-30 e 20-35 ºC) e quatro substratos (areia, vermiculita, pó de coco e papel toalha), com quatro repetições de 25 sementes cada. Foram avaliadas as seguintes variáveis: germinação, primeira contagem da germinação, índice de velocidade de germinação, comprimento e massa seca de plântulas. As temperaturas de 20-30 e 20-35 ºC e os substratos areia e vermiculita são condições adequadas para condução de testes de germinação em sementes de C. pyramidalis.

“…The plant is rich in vitamin C and its fruits and leaves are used to treat cold. The fruits are the most used part of the plant, which are consumed in natura and used to produce juice, jam, ice-cream, liquor, candies, and cachaça (VALLILO et al, 2005). Despite being a savanna native plant, guavira is in risk of extinction because of anthropogenic actions such as burns.…”

ABSTRACT-This study aimed to evaluate different proportions of organic compost and soil as a substrate for the guavira emergence and seedling formation under different protected environments, in the high Pantanal region of the state of Mato Grosso do Sul. The seeds were placed in polyethylene bags (15 x 25 centimeters) filled with four percentages of organic compost (0%, 20%, 80%, and 100% of total volume) mixed with soil. These substrates were tested in agro-nurseries covered with black screen and 50% thermo-reflecting shade cloths. The substrate with 20% soil and 80% organic compost and the black screen shade cloth promote the best performance in the seedling production. Index terms: Campomanesia adamantium (Camb.) Berg, native fruit, protected environments. EMERGÊNCIA E FORMAÇÃO DE MUDAS DE GUAVIRA COM SUBSTRATOS CONTENDO COMPOSTO ORGÂNICO E SOLO SOB DIFERENTES AMBIENTES TELADORESUMO-Este estudo teve como objetivo avaliar diferentes proporções de composto orgânico e solo como substrato para a emergência e formação de mudas de guavira, em diferentes ambientes protegidos, na região do alto Pantanal Sul-Mato-Grossense. As sementes foram acondicionadas em sacolas de polietileno de 15,0 x 25,0 cm preenchidas com quatro porcentagens de composto orgânico (0%; 20%; 80% e 100% do volume total) misturadas ao solo. Estes substratos foram testados em viveiros agrícolas de tela preta e termorrefletora de 50% de sombreamento. O substrato 20% solo e 80% composto orgânico e o ambiente com tela preta promoveram melhor desempenho na formação das mudas. Termos para indexação: Campomanesia adamantium (Camb.) Berg, frutas nativas, ambientes protegidos.
