“…In addition to these properties, other factors, such as its hardiness, short cycle (Paulose;Kandasamy;Dhankher, 2010), low production cost (Jasper;Biaggioni;Silva, 2010), and its oil content greater than 40% (Souza et al, 2009), contribute to making crambe a winter crop option under the climatic conditions of some regions of Brazil (Southeast, South, and Center West).…”

The aim of this study was to adapt the methodology of the accelerated aging and electrical conductivity tests for determination of physiological potential in crambe seeds. Six seed lots of crambe (cv. FMS Brilhante) were subjected to determination of moisture content, germination test, first count germination, emergence, and emergence speed index. For the accelerated aging test, the traditional methodology was used with water, and with a saturated potassium chloride and sodium chloride solution in three periods of exposure (24, 48, and 72 hours) at 41°C; the electrical conductivity test was performed with four pre-soaking treatments (0, 2, 4, and 8 hours) and four soaking periods (4, 8, 16, and 24 hours) at 25°C. The accelerated aging test with water for 72 hours and the electrical conductivity test with 2 hours of pre-soaking and assessment after 16 hours were effective for classification of the crambe seed lots in regard to physiological quality. Index terms:Crambe abyssinica, vigor, physiological quality. RESUMOConduziu-se esta pesquisa, com o objetivo de adequar a metodologia dos testes de envelhecimento acelerado e condutividade elétrica para determinação do potencial fisiológico em sementes de crambe. Seis lotes de sementes de crambe cultivar FMS Brilhante foram submetidos à determinação do teor de água, teste de germinação, primeira contagem de germinação, emergência, índice de velocidade de emergência. Para o teste de envelhecimento acelerado, foi utilizada a metodologia tradicional com o uso de água e com solução saturada de cloreto de potássio e cloreto de sódio em 3 períodos de exposição (24, 48 e 72 horas) a 41°C; o teste de condutividade elétrica foi realizado com quatro tratamentos de pré-embebição (0, 2, 4 e 8 horas) e quatro períodos de embebição (4, 8, 16 e 24 horas) a 25°C. O teste de envelhecimento acelerado com água por 72 horas e o teste de condutividade elétrica com 2 horas de pré-embebição e avaliação, após 16 horas, foram eficientes para a classificação dos lotes de sementes de crambe quanto à qualidade fisiológica. Termos para indexação:Crambe abyssinica, vigor, qualidade fisiológica.

“…Pertencente à família Brassicaceae, o crambe é uma planta de ciclo curto (85 a 90 dias), bastante rústica e tolerante a secas e geadas. O custo de produção é relativamente baixo quando comparado com outras fontes oleaginosas, como canola, girassol e soja (Jasper et al, 2010b), e sua produção de óleo de 35 a 38 % é significativa em relação a outras oleaginosas utilizadas para esta mesma função (Pitol et al, 2010). A propagação do crambe ocorre por via seminífera, e suas sementes são envolvidas por uma estrutura denominada pericarpo.…”

“…Other advantages of the cultivation of crambe refers to its rapid cycle (Chhikara et al, 2012), high biomass production (Zulfiqar et al, 2011), elevated amount of seeds (Falasca et al, 2010), low production cost in relation to other oilseeds (Jasper et al, 2010), resistance to insects (Kmec et al, 1998), percentage of total oil in the seed (32 to 38%), which surpasses that of soybean (Falasca et al, 2010), and elevated percentage of erucic acid in the oil extracted from the seeds (50-60%), useful in the plastic and lubricant industry (LaraFiorezea et al, 2013). Moreover, the culture has potential for phytoremediation against heavy metals .…”

Crambe abyssinica Hochst. Ex. R. E. Fr. is an oilseed species that produces non-edible oil, initially employed in Brazil as a culture for soil surface coverage and animal feed. However, with stimulation of the production and use of renewable energies, it arose as an interesting alternative for biodiesel production. The aim of this work was to describe a protocol for micropropagation of crambe, using apical segments as explants. Crambe seeds germinated in vitro in medium MS½ provided apical segments adequate to the micropropagation process. In the shoot induction phase, testing the interaction of the cytokinins 6-benzylaminopurine (BAP), kinetin (KIN) and thidiazuron (TDZ) as well as different concentrations thereof, the highest numbers of shoots per explant were obtained with 5 µM BAP at 30 days (9.26 shoots) and 15 µM BAP at 60 days (18.08 shoots) of in vitro culture. In the elongation with 1 µM gibberellic acid (GA 3 ), the mean length of the shoots turned from 3.61 cm to 5.03 cm after 30 days. The highest percentage of rooting was of 30% with 0.25 µM naphthalene-acetic acid (NAA). The results of this work revealed a satisfactory frequency of shoot regeneration from apical segments of crambe in media containing 5 µM BAP, and adequate elongation with 1 µM GA 3 . Nevertheless, there is still need for efficient rooting and acclimatization for complete in vitro propagation of crambe.
