Abstract
Five months old Teak drupes were subjected to following pre sowing treatments viz., soaking in water followed by drying (S-D) at 12 hr interval for 6 days, S-D for 5 days at 12 hr interval then 6th day soaking in different concentrations of Calcium hydroxide (Ca (OH)2-2,4,6,8 and 10%), Potassium hydroxide (KOH -2,4,6,8 and 10%) and Sodium hydroxide (NaOH – 2,4,6,8 and 10%) solutions for 12 hr, compared to dry drupes served as control. The pre conditioned and control drupes were placed for germination in sand under open sunlight. An 28 days after sowing, the results revealed that the highest germination of 48% and seedling vigour of 983 was recorded with the drupes soaked in water followed by drying (S-D) at 12hr interval for 5 days then on 6th day soaking in 6% Ca(OH)2 for 12hr. The control treatment recorded only 12% germination and seedling vigour of 123.
