“…In this study, the centesimal composition results are in agreement with those found by Goudel et al (2013), but for coimbra and Jorge (2011), different values were observed for the species. Variations in the contents of chemical components in palms of the same species can be caused by genetic factors, differences in edaphoclimatic conditions or cultivation regions (NeIDA;elBA, 2007;BORGeS et al, 2011;MhANhMAD et al, 2011).…”

“…These characteristics were similar to fruits of L. chinensis that presented weight of 2.15 g, length of 1.92 cm and diameter of 1.58 cm, while seeds weighed 1.07 g, observing the length of 1.38 cm and diameter of 1.04 cm (PÊGO et al, 2013). Goudel et al (2013) reported that Syagrus romanzoffiana palm presents variation in fruit, pulp and seed mass, which can be explored for breeding projects and should be considered in the formation of seed lots that are more homogeneous.…”

“…Thus, with increasing the size of seeds the pulp thickness of the fruits is lower. The polar diameter of fruit of Jeriva palm (Syagrus romanzoffiana) showed a significant positive linear correlation with fruit mass, pulp mass, seed mass and polar diameter of the seed (GOUDEL et al, 2013). Pedron et al (2004) observed that Buriti palm (Butia capitata (Mart.)…”

“…The substrates requirements to seed germination vary according to specie. One of the main factors that affecting the growth of areca palm is the physical and chemical proprieties of substrate (KLOCK-MOORE and BROSCHAT, 2001). Thus, a suitable substrate must contain the physical and chemical proprieties that enable rapid seed germination and seedling emergence.…”

Areca palm (Dypsis lutescens) is an ornamental palm largely used in landscape which propagate occur by seeds germination. However, the biometry and the endogenous and exogenous factors than can limit propagation of this plant are poorly known. Thus, this study aimed to characterize the biometric fruits and seeds of areca palm and to evaluate the seed germination after the dormancy breaking treatments in different substrates. For this, the biometric analysis of length, diameter and weight were recorded; the description of internal and external morphology of fruit and seed were also studied. The treatments to improvement of seed germination were control (T1); immersion of seeds in water a solution of 500 mg L -1 GA 3 (T2), mechanical scarification with sandpaper (T3) and combination of mechanical scarification followed of immersion in 500 mg L -1 GA 3 (T4). The seeds were sown in containers containing sand, coir dust or vermiculite in all possible combinations. The areca palm fruits and seeds are both, elliptical shape and the weight of fruits and seeds is 1.70 g and 1.04 g, respectively. There is positive correlation between fruit weight and length and diameter of the fruit and just like the diameter has a positive correlation with the diameter of the seed. The mechanical scarification improve the seed germination. The Coir dust is the most appropriate substrate to seed germination of areca palm. The seed germination of Areca palm is hypogeal and the protrusion of the haustorium was observed at 59 days after sowing and the plantlets is fully grown at 153 after sowing. Keywords: Areca Palm, Dypsis lutescens, seedling, morphology. RESUMO Biometria de frutos e sementes, dormência e substratos na germinação de sementes de germinação Dypsis lutescensPalmeira areca (Dypsis lutescens) é uma palmeira ornamental amplamente utilizada no paisagismo que se propaga principalmente por sementes. No entanto, a biometria e os fatores endógenos e exógenos que podem limitar a propagação desta planta são pouco conhecidos. Assim, este trabalho teve como objetivo caracterizar a biometria de frutos e sementes de palmeira areca e avaliar a germinação de sementes após tratamentos de superação de dormência e em diferentes substratos. Para isso, as análises biométricas de comprimento, diâmetro e peso foram registradas; a descrição da morfologia externa e interna de frutos e sementes também foram estudados. Os tratamentos para superação de dormência foram: controle (T1), imersão das sementes em solução de 500 mg L -1 de GA 3 (T2), escarificação mecânica com lixa (T3) e combinação de escarificação mecânica após imersão em 500 mg L -1 de GA 3 (T4). Para cada tratamento de superação de dormência foram testados areia, pó de coco ou vermiculita. Os frutos e sementes de palmeira areca são elípticos o peso dos frutos e sementes são de 1,70 g e 1,0 4 g respectivamente. Há correlação positiva entre o peso do fruto e comprimento e diâmetro do fruto assim como o diâmetro do fruto também tem correlação positiva com o diâmetro da semente. A esca...

“…Studies have reported low germination percentages for S. romanzoffiana seeds in the laboratory (Broschat, & Donselman, 1987;Brancalion et al, 2011;Goudel, Shibata, Coelho, & Miller, 2013), suggesting that the seeds have a certain degree of dormancy. The presence of dormancy and the ability to form persistent seed banks are adaptive strategies of plant species to overcome unfavorable periods for germination and/or seedling establishment (Moles, Warton, & Westoby, 2003;Long et al, 2015).…”

Syagrus romanzoffiana is a palm tree native and widely distributed of South America. The present study investigated the longevity and germination of the buried seeds of this species in an experimental seed bank. Laboratory germination and viability tests were performed for comparison with field results. Pyrenes (seeds enclosed by the endocarp) were buried in a forest fragment edge in July 2012 (dry season) and exhumed monthly during one year, for the assessment of water content and percentage of germinated and viable seeds. Germination tests were conducted in a Mangelsdorf-type germinator at 30°C under constant light and the viability was assessed by the tetrazolium test. An additional sample of pyrenes was buried to evaluate the percentage of seedling emergence and survival. Climatic and soil moisture data were recorded. In the laboratory, the pyrenes were stored for one year in a temperature-controlled room at 20ºC and 75% (±10%) relative air humidity to assess changes in the percentage of germination and viability over time. In the field, a reduction in seed viability was observed over the study period, with a total loss of viability of non-germinated seeds at seven months after burial. The maximum germination (close to 26%) was observed in the samples that were exhumed between five and seven months after burial. In the field, seedling emergence did not exceed 10% and seedling mortality was not observed. The percentages of germination and of viable seeds decreased both in burial and stored seeds. The stored seeds maintained viability at up to six months, with marked reduction thereafter. After the germination tests (four months) in the laboratory, all of the remaining seeds were nonviable. The ecological, physiological and reproductive characteristics of the species are discussed, and we concluded that S. romanzoffiana seeds have short longevity after imbibition, and low potential for soil seed bank formation.
