Seed germination remains to be an unsolved problem in teak. Studies made on
radiography and seed technological aspects using drupes from India and Thailand
disclosed certain important features. Radiography has been standardised for sharp
image to read the anatomical potential of seed. Teak drupes from two provenance
differed in size and weight within and between seedlots. Radiograms revealed the
development of 4, 3,2 and 1 seed in the tetracarpellary ovary in the order of 1,5,19
and 48% with 27% empty drupes. When drupe size decreased the percentage of
single-seeded and empty drupes increased correspondingly. Teak drupes possess
ontogenic and dormancy problems posing challenge to germination
