“…The results presented here are in accordance to those of Matos et al (2008), Pacheco and Matos (2009) and Guedes et al (2013), who showed that the seeds of Apeiba tibourbou resist to prolonged storage and present high germinability after scarification of the tegument. In the present study, the thermal scarification helped in the disinfestation of the explants.…”

Apeiba tibourbou is a common species found in the rainforests of South America. The aim of the present work is to determine the most favorable condition for micropropagation. Seeds were submitted to both thermal and mechanical scarification, sterilized and inoculated in test tubes with ½ MS, with or without the addition of sucrose. The explants were divided in a factorial experiment of four concentrations (0; 0.1; 0.5 and 1.0 mgL -1 ) of 6-benzylaminopurine (BAP) and three auxins at the concentration of 0.01 mg.L -1 : indole-3-acetic acid (AIA), indole-3-butyric acid (AIB) or naphthalene-acetic acid (ANA). Regarding the production of new sprouts, auxins had an inhibitory effect on sprouting, and the best results were obtained with BAP at the concentration of 0.5 mgL -1 without auxins or with AIA. However, regardless the culture medium the sprouts died in the following subculture. All the explants cultivated in the absence of growth regulators rooted. All combinations of growth regulators inhibited the formation of roots, except in the presence of AIA alone. The multiplication using sprouts formed in vitro remain a challenge to overcome.

“…The moisture content of 40%, associated to temperature of 10 ºC, allowed conservation of seeds of Cupania vernalis Cambess during a period of 240 days (Vieira et al, 2008). Seeds of Apeiba tibourbou Aubl., can be stored under normal environment of laboratory using as packaging either Kraft paper bags or polyethylene bags (Matos et al, 2008). The packaging into cans and maintenance into refrigerator were an adequate condition for storing seeds of Tabebuia roseo-alba and Tabebuia impetiginosa (Borba-Filho and Perez, 2009).…”

-Tabebuia caraiba (Mart.) Bureau, commonly known as Silver Trumpet Tree is a forestal species, belonging to Bignoniaceae family, which can be utilized as medicinal plant or in landscaping of urban and rural areas; besides producing large mechanical resistance wood. Despite its wide use and ecological importance, basic studies on storages of their seeds are scarce. This way, the objective of this study was to determine the most adequate packaging and the best temperatures, for storing seeds of T. caraiba. For this, seeds were stored in two types of packaging: Kraft paper bags and transparent polyethylene bags; which were then stored during 150 days under three different environments: laboratory normal environment (25±2 °C); cold chamber (8±2 °C); and refrigerator (6±2 °C). After periods of 0, 30, 60, 90, 120, and 150 days, seed moisture content, percentage of emergence, emergence speed index, and seedling length were evaluated. Seeds of T. caraiba kept in packaging of paper and polyethylene bags and stored at laboratory environmental condition, have lost more quickly their vigor along the storage period. For storage, it is recommended the maintenance of T. caraiba seeds in polyethylene bags into cold chamber; and/or polyethylene bags or Kraft paper bags into refrigerator.Index terms: emergence, vigor, seed preservation. Armazenamento de sementes de Tabebuia caraiba (Mart.)Bureau em diferentes embalagens e temperaturas RESUMO -Tabebuia caraiba (Mart.) Bureau, conhecida popularmente por craibeira, pertencente à família Bignoniaceae é uma espécie florestal utilizada na medicina popular e na arborização urbana e rural; além de produzir madeira de alta resistência mecânica. Apesar de seu uso e importância ecológica, os estudos básicos sobre o armazenamento de suas sementes são escassos. Desta forma, o objetivo neste estudo foi determinar as embalagens mais adequadas e as melhores temperaturas, para o armazenamento de sementes de T. caraiba. Para tanto, as sementes foram acondicionadas em dois tipos de embalagens: sacos de papel Kraft; e sacos de polietileno transparente; e armazenadas por 150 dias, em três ambientes: natural de laboratório (25±2 °C), câmara fria (8±2 °C) e geladeira (6±2 °C). Após períodos de 0, 30, 60, 90, 120 e 150 dias foram determinados: grau de umidade; porcentagem de emergência; índice de velocidade de emergência e comprimento de plântulas. As sementes de T. caraiba acondicionadas nas embalagens de papel e polietileno e armazenadas no ambiente de laboratório perderam mais rapidamente o vigor ao longo do armazenamento. Para o armazenamento recomenda-se a manutenção das sementes em sacos de polietileno em câmara fria; e/ou em saco de polietileno ou de papel Kraft em geladeira.Termos para indexação: emergência, vigor, conservação de sementes.1

“…At these three evaluation times, the average water content of seeds stored in polyethylene bags was higher than that of seeds kept in paper bags (Table 1). Matos et al (2008) verified that the packaging influenced the water content of Apeiba tibourbou seeds only after 90 days of storage, and that seeds stored in polyethylene bags had water content lower than those stored in paper bags, regardless of the environment.…”

Germination and vigor of seeds of Magonia pubescens A. St.-Hil. submitted to storage and pre-imbibition in water

ABSTRACT-Timbó (Magonia pubescens A. St.-Hil.) is a species with ornamental potential, which can be used in composition of gardens, squares and especially in streets landscaping. It is also suitable for planting in degraded areas of permanent preservation. This work aimed to verify the effect of seed size, storage and pre-imbibition time on seed germination and vigor. The test design was completely randomized, in a plot scheme subdivided in time. The main plots were seed size (large and small), packaging (0.5 mm-thick transparent polyethylene and kraft paper bag), and time of imbibition in water (0, 12 and 24 hours); and as subplots, it was considerate the storage times (0, 3, 6, 9 and 12 months). The tests were carried out in five replications of ten seeds, and the evaluated variables were: water content of the seeds, percentage of germination (% G), mean germination time (MGT), shoot height (cm), collar diameter (mm), number of leaves, and fresh and dry mass of the aerial part (g). The size of the seed did not influence the germination percentage, but large seeds formed more vigorous seedlings. The storage did not affect seeds germination, nor the vigor of the seedlings. Seed preimbibition did not influence the percentage of germination, but the mean germination time decreased, and more vigorous seedlings were formed. In order to obtain more vigorous Timbó seedlings, the best option is to use large seeds. They can be stored for up to 12 months without losing vigor and pre-soaked to accelerate the beginning of germination, thus forming a more homogeneous lot of seedlings. . Index terms: timbó, Sapindaceae, native plant, seed storage.Germinação e vigor de sementes de Magonia pubescens A. St.-Hil. submetidas ao armazenamento e pré-embebição em água RESUMO -O timbó (Magonia pubescens A. St.-Hil.) é uma espécie com potencial ornamental, podendo ser usado na composição de jardins e praças e, principalmente, para arborização de ruas; é ainda indicado para plantios em áreas degradadas de preservação permanente. O objetivo neste trabalho foi verificar o efeito do tamanho das sementes, do armazenamento e do tempo de pré-embebição das sementes na sua germinação e vigor. O delineamento utilizado foi inteiramente casualizado, em parcela subdividida no tempo, sendo alocados na parcela principal: tamanho da semente (grandes e pequenas), embalagem (polietileno transparente com espessura de 0,5 mm e saco de papel kraft) e tempo de embebição em água (0, 12 e 24 horas); e nas subparcelas o tempo de armazenamento (0, 3, 6, 9 e 12 meses), com cinco repetições de dez sementes. As características avaliadas foram o teor de água das sementes, a porcentagem de germinação (%G), o tempo médio de germinação (TMG), a altura da parte aérea (cm), o diâmetro do colo (mm), o número de folhas e as massas fresca e seca da parte aérea (g). O tamanho da semente não influenciou na porcentagem de germinação, porém, as sementes grandes formaram plântulas mais vigorosas. O armazenamento não prejudicou a germinação das sementes, nem mesmo o vigor das p...
