“…These results corroborate those obtained by Lessa, Ferreira, Araújo Neto, and Souza (2013) and Ferraresi, Yamashita, and Carvalho (2009), who also found superiority of red and white light for the germination of Emilia coccinea (Sims) G. Don. and Murdannia nudiflora (L.) Brenans seeds, respectively.…”

“…This may have occurred because they are more exposed to daily temperature fluctuations, when located on the soil surface, contributing to increase emergence (Canossa et al, 2007). On the other hand, the decrease on the emergence as the sowing depth increased may be related to the fact that greater depths represent a physical barrier imposed by the soil, and since these are small seeds, their reserves are insufficient for them to emerge at greater depths (Canossa et al, 2007;Lee et al, 2011;Luz et al, 2014), creating a seed bank on the soil (Lessa et al, 2013).…”

“…The temperature may directly or indirectly affect the germination, affecting the feasibility of the seeds, dormancy overcoming, deterioration, water absorption speed and biochemical reactions of the germination process (Marcos-Filho, 2015;Mahmood et al, 2016). Light may have a direct influence on the germination of the seeds, and it is associated to a dormancy mechanism, by controlling the substances that promote and inhibit germination, controlled by the phytochrome (Vivian et al, 2008;Lessa et al, 2013). When the seeds need light to germinate, they are characterized as positive photoblastic seeds, when their germination is reduced or inhibited in the presence of light, they are negative photoblastic seeds, and when their germination occurs regardless of the light, they are neutral photoblastic seeds (Marcos-Filho, 2015).…”
