“…Such information is fundamental to know the germination potential and use of each source, serving as an indicator of anticipation in obtaining better quality seedlings, as well as to assist in recommending and supporting programs for the recovery of degraded areas, conservation, resources and also to evaluate the genetic variability within populations of the same species (Mendonça et al, 2016;Ken-iti Yokomizo et al, 2016;Bardales-lozano et al, 2016;Silva Moura et al, 2016;Oliveira et al, 2016).…”

Andiroba (Carapa guianensis Aubl.-Meliaceae) is considered an Amazonian forest species with great potential for multiple use in natural forests. Because it is a native species of the Amazon rainforest, it has great socioeconomic importance for the extractive population due to the oil extracted from its seeds. The speed of emergence is an important factor in the establishment of seedlings, since the longer the seeds remain inside the soil, the seeds are in the soil, the greater the chances that the seeds will be attacked by fungi and soil insects. The objective of this work was to determinate the speed of andiroba emergence (Carapa guianensis Aubl.) seedlings and the development. The experiment was carried out in a greenhouse belonging to Federal Rural University of Amazonia (UFRA)-Capitão Poço, Brazil. Fruits of C. guianensis were collected in floodplain areas in northeastern of Pará. The treatments were arranged according to the seed mass. Were calculated 5 variables after sowing (emergence speed index; height; interference of the mass of andiroba seeds at the height of the seedlings stem; interference of the mass of andiroba seeds in the number of leaves; interference of the mass of andiroba seeds in the number of leaflets). The experimental design was completely randomized, consisting of 4 treatments with 5 replicates with 5 seeds per replicate (5 seeds per vessel), totaling 25 seeds per treatment. The data were statistically analyzed using the Tukey test at 5% probability with the software Assistat 7.6. The seed mass classes did not influence ESI (Emergence Speed Index). The seed mass promoted significant effects on 4 variables. The mass of the seeds of andiroba does not influence the ESI of seedlings for it own production. The heavy and very heavy seeds generated more developed plants.

“…The physiological potential of seeds is inherent to each species. Some studies in the literature argue that the external characteristics of fruits and seeds are important for the understanding of the germination of forest species (Lopes et al, 2005;Silva et al, 2015;Mendonça et al, 2016). As observed by the mini-SAS system, no difference was found regarding external characteristics, therefore, we do not recommend the use of such parameters when doing qualitative evaluation of M. polymorphum seed lots.…”

This study aimed to analyze the physical properties of the seeds of Moquiniastrum polymorphum when processed by mini-SAS, X-ray and seed blower systems. The seeds were purchased from Seeds Caiçara, located in Penápolis-SP. After purchase, the seed lot was characterized by standard tests. In the X-ray test the seeds were classified according to their internal morphology as filled, unfilled or malformed. The seed blower was set at six opening settings, resulting in light and heavy fractions. The evaluations were performed by weighing the seeds that remained in the blower (heavy fraction) and by the amount of filled seeds indicated by the X-ray test. The germination tests were composed of four replicates of 50 seeds. The mini-SAS was used for external evaluation. It was concluded that the combined use of the seed blower and the X-ray test was efficient for the evaluation and determination of the physical quality of the seeds of M. polymorphum. The seed blower at opening settings 5 resulted in the best lot quality. The external parameters were not able to qualitatively evaluate the seeds of M. polymorphum.

“…De acordo com Borges e Piani (2013) [9], o gênero Senegalia não apresentam septos e suas sementes são livres, porém no presente estudo foi verificado que as sementes estão presas ao fruto pelo funículo contorcido. [21] também observaram em Clitoria favichildiana e Poincianella piramidalis, espécies leguminosas, a presença de falso septo. Lima (1985) [17], também observou para espécies dessa família a presença do funículo, e que de acordo com o autor, também se apresenta longo e espiralado.…”

Os objetivos foram descrever e ilustrar morfologicamente frutos, sementes e plântulas de Senegalia bahiensis, além de suas biometrias. Os frutos foram colhidos em árvores-matrizes no município de Castro Alves - BA - Brasil. As avaliações e observações foram feitas mediante uma amostragem aleatória de 100 frutos de cada matriz. Para o fruto avaliaram-se: tipo; cor; comprimento, largura, textura, número de sementes sadias e bem formadas por fruto e número de falsos septos. Sendo o comprimento mensurado com régua milimetrada e a largura foi medido com o auxílio de um paquímetro digital de precisão0,1 mm. As características biométricas e morfológicas das sementes observadas foram: cor, dimensão, forma, hilo, calaza, tegumento e embrião. O acompanhamento do desenvolvimento das plântulas foi realizado em casa de vegetação com sombrite 50%. Foi realizada a descrição das partes das plântulas, como: raiz, coleto, cotilédones hipocótilo, epicótilo, tipo de germinação, primeiro par de eófilos, além da tomada de comprimento da raiz primária, comprimento do hipocótilo e do epicótilo com auxílio de uma régua milimetrada. Os dados biométricos foram submetidos à análise descritiva calculando-se a média, máximo e mínimo, coeficiente de variação e erro padrão da média. Características dos frutos como sua deiscência, forma, coloração e sua textura; das sementes, como presença de pleurograma, calaza e posição do embrião; das plântulas como presença de estípulas interpeciolar e da filotaxia dos folíolulos, constituem-se como elementos que auxiliam para identificação da espécie no viveiro e em laboratório, como também no campo em trabalhos de regeneração natural.
