Evaluates chemical treatments for improving seed germination and survival in Atropa belladonna, suggesting effective methods for propagation.
The hard coated seeds of Atropa belladonna Linn. were treated with 100, 75, and 50% concentration of Sulphuric acid (H2SO4) for 2, 7, 12, and 17 minutes duration. Treatment of seeds with 75% of H2SO4 for 2 minutes followed by 30% sodium hydroxide (NaOH) for 5 minutes showed good germination (96.55%) and survival of seedlings. Gibberelic acid (GA3) and Indol Buteric Acid (IBA) at the concentration of 30 ppm resulted in best germination and seedling survival.
