Treatments to Break Seed Dormancy in Givotia rottleriformis Griff

The propagation of Givotia rottlerformis Griff is troublesome as consequence of it is long seed dormancy associated with poor seed germination. The breaking of seed dormancy is administered by environmental factors, including temperature, light, nitrate, and smoke constituents. Givotia seeds were treated with Scarification, Chilling, Hot water and Growth regulators in order to break its dormancy and enhance the germination percentage. The maximum seed germination percentage (50%) was obtained when seeds treated by Mechanical Scarification.
