Acacia farnesiana L. is a species known for its uses in recovery of degraded pastures, animal feeding, medical and fungicide properties. However, it is one of the most problematic invasive species in agriculture, due to the little known dormancy aspects of its seeds that results in the propagation and dispersion to distinct areas and the establishment of the invasive plant. The knowledge on ecophysiological characteristics of invasive species seeds aiming at the dormancy process is important for the comprehension of aggressive regeneration unities, and allows the development of strategies against infestation of new areas and reduction of soil seed banks. The objective of this research was to assess how A. farnesiana seeds overcome dormancy using different temperatures and pre-germinative treatments. The study was conducted in Federal University of Paraiba, using seeds obtained from fruits of ten matrix trees in Paraiba State, Brazil. The completely randomized design was adopted, with treatments arranged in a 3 x 15 factorial scheme representing temperatures and pregerminative treatments with four replicates. Parameters related to germination percentage, germination and emergency index were assessed, with best results observed in seeds scarified with sandpaper 80 followed by imbibitions of water at environmental temperature (25-30°C) for 24 h.

“…Entre os pré-tratamentos utilizados para quebra de dormência tegumentar, destacam-se a escarificação mecânica, imersão em ácido sulfúrico, água quente, hipoclorito de sódio e ácido giberélico (Rodrigues et al, 2009;Dalastra et al, 2010;Kabori et al, 2013;Sperandio et al, 2013).…”

“…Seeds of many species, although viable and under favorable conditions, have non-uniform and slow germination and sometimes they remain as dormant and do not germinate. Immature embryos, presence of substances that inhibit germination and impermeability of seed coat to water and gases, which restricts embryo growth, are among the most frequent causes of seed dormancy (Metivier, 1979;Fowler & Bianchetti, 2000;Rodrigues et al, 2009).…”

Methods for overcoming dormancy in Stryphnodendron pulcherrimum seeds

2016

Seed dormancy is a phenomenon observed in several tropical species. This condition causes low and non-uniform germination. The present study was designed to identify an efficient method of breaking seed dormancy in Stryphnodendron pulcherrimum. Seeds of four mother plants were subjected to the following treatments: immersion in sulfuric acid for 2, 4, 6, 8, 10 and 12 min and scarification on 150-grit sandpaper. Seeds were sown on substrate containing sand and sawdust (1:1). It was evaluate the days to onset seedlings emergence, seedlings emergence (SE), emergence speed index (ESI), germination (G), hard seeds (HS), dead seeds (DS), dormant seeds (DMS), abnormal seedlings (AS) and dry mass of aerial part (DMAP) and roots (DMR). The experimental design was completely randomized with four replications of 25 seeds for each treatment. Data were subjected to analysis of variance and means compared by Tukey's test (p < 0.05). Significant differences among treatments were observed for ESI, SE, G, HS, DMAP and DMR. Highest HS was observed in control treatment (85%). Highest G was observed in seeds scarified with sulfuric acid for 10 min (82%) and 12 min (74%). These treatments also showed highest ESI, DMAP and DMR, indicating that these scarification treatments were the most efficient in overcoming dormancy.
