Effect of pre-sowing treatments on seed germination and seedling growth of Tetracarpidium conophorun Mull.

Pre-sowing treatments were evaluated for Tetracarpidium conophorum. Mechanically scarified T. conophorum seeds soaked in indole acetic acid for 24 h yielded 90% seed germination. Smoked- and sun-dried seeds for 14 days yielded 73 and 33.3% seed germination, respectively. Poorest values were obtained from acid treatment (0%), while the control had 20%. The tough seed coat is the main germination problem.
