AMARO, H.T.R. et al. Overcoming dormancy in seeds of basil (Ocimum basilicum L.). Rev. bras. plantas med. [online]. 2012, vol.14, n.spe, pp.218-223. ISSN 1516-0572. http://dx.doi.org/10.1590/S1516-05722012000500016.
Aiming in order to assess the effectiveness of treatments to overcome dormancy in seeds of basil, an experiment was conducted at the Laboratory of Seed Analysis of Unimontes. Following determinations were performed to evaluate the physiological quality of seeds, water content, germination, first count germination, seedling emergence and emergence speed index. The experimental design was completely randomized design with four replications of 50 seeds per treatment, which consisted of: T1 - control, T2 - pre-cooling of the seed chamber BOD at a temperature of 10ºC for 4 days, T3 - soaking the seeds in water distilled for 24 hours, T4 - soaking the seeds in a solution containing 0,2% for 5 minutes and T5 - submitted seeds in distilled water at 70ºC for 5 minutes. Data were subjected to analysis of variance and the averages compared by Scott-Knott 5% probability. The pre-cooling treatment in BOD chamber at 10ºC for 4 days reduced dormancy and promotes increases in the physiological quality of seeds of basil.
