Abstract

Delayed and non-uniform germination of seed due to hard and thick pericarp of the fruit, is the main hindrance in producing teak (Tectona grandis ) seedlings. This study was intended to develop a seed treatment technique to enhance germination of teak seeds, which is efficient, cheap and uses locally available materials. A total of 16 treatments under five broad categories, viz., hot water (90-100o C), cold water (room temperature, 20-25o C), cow dung diluted in water (dung: water, 3:10), soil pits and fungal attack were tested. Alternate soaking in cold water and sun drying at 24 hours interval continued up to seven days showed best germination success (61.11%). Thus, for practical use in Bangladesh these two pre-sowing treatments are recommended for germination of teak seeds.
