The study deals with the anatomy of callus induction and organogenesis of wheat em-
bryo in vitro culture.The study results indicated that theinitial part of callus induction was af-
fected by the age of embryos used.Different parts of embryo varied in reacting to culture in
vitro.The ability of scutellum to initiate callus decreased along with the increase of embryo
age.The scutella of 3-week-aged or older embryo couldn't produce any callus but secrete α-
amylase,abs...
