Teak drupes were collected from seven geographical locationsspread over four forest types (dry deciduous, moist deciduous, verymoist deciduous, and semi-deciduous) from India. In order to study thedormancy mechanism associated with teak true seeds. The true seedspresent inside the drupes from each provenance were extracted withoutcausing any damage to the true seeds. The extracted true seeds wereused to study the morphological and physiological characteristics.The true seeds were carefully inoculated in MS medium to observegermination. Twenty-eight days after sowing, the result revealed thatAndhra Pradesh provenance recorded the highest true seed germinationof 58 percent compared to all other provenances. These results clearlyindicate that not only physical and mechanical dormancy is involved inteak for decreased germination but also morphological/physiologicaldormancy plays a major role in teak true seed germination
