Abstract

Seed dormancy limits the seedling production and potential of use in Adenanthera pavonina L. The objective of this research was to evaluate the best dormancy breaking method in Adenanthera pavonina L. seeds. It was carried out at the Ceulji/Ulbra Laboratory of Botany, from April to June 2007, and six dormancy breaking treatments (T) were tested: T1 - Boil for 15 minutes and rest for 16 hours, in the same water; T2 - Boil for 10 minutes and rest for 16 hours, in the same water; T3 - Immersion in boiling water (95ºC) and rest for 24 hours, in the same water; T4 and T5 - Immersion in concentrated sulfuric acid (98%), for 5 and 10 minutes, respectively; and T6 - Control. The following items were evaluated: days until germination, germination speed index (GSI), and germination percentage (%GER). Variance analysis was used to evaluate the data and means were compared by using the Duncan’s test (5%). Treatments 1 and 2 caused seeds damage, preventing their germination. Treatments 4 and 5 showed no significant differences, but were more favorable to dormancy breaking, if compared to the other treatments.

KEY-WORDS: Germination; chemical scarification; boiling; sulfuric acid.
