Abstract
Preliminary studies on the germination of teek seeds (Tectona grandis L.) were carried out at the institute of Plant Sciences, University of Sindh by subjecting the seeds with some physical and chemical methods. The viability of seeds were confirmed by 2,3,5- triphenyltetrazolium Chloride. Results revealed that by altering temperature at the germination stage the inhabitatry effect of seed coat was reduced. However scarification treatment with GA3, Kinetine, H2SO4 and KNO3 also promote the seed germination due to increased softening of the seed coat.
