Germination of Mimosa scabrella Benth. seeds under different conditions of temperature, storage, and pre-germinative treatments

Abstract

The objective of this study was to evaluate the effect of temperature, storage time and pre-germination treatments in the germination of Mimosa scabrella Benth seeds. The study was conducted at the University of the State of Santa Catarina, Lages. The experimental design was completely randomized, and analysis of variance was performed under the factorial 2×2×7 (two temperatures, two periods of storage, and seven pre-germination treatments). The average values were compared by Scott-Knott test at 5% probability. The temperatures employed were 25 and 30°C, the storage periods were eight months and no storage and pre-germination treatments were immersion in water at 80°C for periods of 3, 6, 9, 12, 15 and 18 hours. The results showed higher germination of seeds bracatinga in temperature 30°C, regardless of storage, and immersion for 3 hours in water at 80°C.
