Germinação de sementes e emergência de plântulas de <i>Anadenanthera colubrina</i> (Vell.) Brenan var. <i>cebil</i> (Griseb.) Altschut, Fabaceae, estabelecida em fragmentos florestais do Cerrado, MG

Abstract: http://dx.doi.org/10.5902/1980509810541A estratégia de germinação dos diásporos é fundamental para a sobrevivência das espécies, sendo um dos fatores que permitem a sua manutenção e regeneração no ambiente. A germinação das sementes e a emergência das plântulas de Anadenanthera colubrina foram estudadas para analisar a eficiência reprodutiva da espécie, oriunda de fragmentos de vegetação do bioma Cerrado. Os frutos foram coletados no Vale do Rio Araguari, MG. O teor de água a 105ºC, a germinação em condições c… Show more

“…The percentage of emergence of scarified seeds in 2005 was 98. 6, 79.2, 77.8, 100, 79.2, 86.1 and 5.6 for mother plants 1 to 7, respectively (Dorneles 2010). The first emergence in 2005 occurred after six days of sowing and the last after 35 days, with the mean emergence time from 9.8 to 15.9 days, showing that the process became slower after three years of storage.…”

“…In contrast, the alternating temperature 20-30 and the temperature of 30 °C in freshly harvested seeds and seeds with 12 months of storage did not differ statistically, resulting in a unimodal behavior, which may suggest that these conditions may develop a physiological similarity in the seeds, causing uniformity in the germination. Dorneles, Ranal, and Santana (2013) declare that the lower asynchronicity in Anadenanthera colubrina germination and emergence values derive from the greater stability of thermal and humidity conditions of the germination environment.…”

“…A falta de homogeneidade registrada para os processos de germinação e emergência de espécies de Anadenanthera parece ser um comportamento comum entre as espécies nativas, sendo registrado por diversos autores (CARVALHO et al, 2005;DORNELES et al, 2005;DORNELES et al, 2013). Apesar de diversos trabalhos relatarem sobre a germinação e emergência das sementes de angico (Anadenanthera sp.)…”
