Abstract: Germination of the guava seeds is almost poor, uneven and takes a long time because of the hard seed coats. The effect of different concentrations of gibberellic acid, hydrogen peroxide and bleach solution on guava (Psidium gujava L) seeds were therefore investigated to hasten and enhance this process. The seeds were extracted from the guava fruits and were soaked in 100, 300, 500 ppm GA3 concentrations, H2O2, bleach solution and a control treatment (distilled water) for 24 hrs. Germination was earlier (20 days after sowing) and higher in the GA3 concentrations than the seeds received any other treatments. After final measurement, the highest percent germination (40%) occurred in 300 ppm GA3 while the lowest (22%) noticed in the bleach solution. The seedlings of the bleach treatment didn’t have primary leaves and died soon after they emerged.
