ABSTRACT
Ngulube, M., 1986. Preliminary study on germination of pretreated seed of teak (Tectona grandis) under nursery conditions in Zomba, Malawi. For. Ecol. Manage., 17: 147-151.
Seeds of teak ( Tectona grandis Linn. F.) were pretreated using ten different treatments beforesowing in the nursery. Germinated seeds were counted weekly until 20 weeks after sowing to assessthe effect of pretreatment on germination.
Germination percentages were generally low, ranging from 0% to 32.5% by 20 weeks after sowing.The 96-h stream-soaked pretreated seed demonstrated superiority, followed by seed pretreated by container soaking for 96 h and alternate drying and wetting for I week. Scorching led to no germination at all, whereas stream soaking for 72, 48 and 24 h achieved only about 3% germination each.
It is therefore recommended to soak the seed of teak in running water for 96 h before sowing in the nursery to effectively improve germination.
