Abstract

Studies were conducted to find out the germination and seedling vigour of 7 month-old teak drupes (fruit with seed). The drupes were subjected to presowing treatments and germinated in open and mist chamber condition. The study revealed that soaking and drying of drupes for 5 days at an interval of 12 hr followed by soaking in 4.5% Potassium nitrate solution recorded 52.0% germination in mist chamber accounting for an increase of 39.0% over the control. The corresponding seeds germinated in open condition gave a maximum of 40.0% (23.0% over control) with 1.0% KNO3 pretreatment. In addition to enhanced germination in mist chamber, seedling emergence took place within 8-12 days as against 12-18 days under open condition.
