IMPACT OF ACID SCARIFICATION AND COLD MIST STRATIFICATION ON ENHANCING SEED GERMINATION AND SEEDLING EARLY GROWTH OF Albizia lebbeck (L.) Benth.

The thick, hard and water-impermeable seed coat cause physical dormancy and low germination rate in <em>Albizia lebbeck</em> (L.), to overcome this physical dormancy, seeds were pretreated with concentrated HCl and cold mist condition. Immersing seeds in concentrated HCl acid 37% for 30...
