If you be right at least for the reproductive stage , should we
say that if :
50 in Zadoks stage is infloresence stage so 49 is equal to
End of Vegetative ( a rough estimate )
 
and if:
60 in zadoks is anthesis so 59 is another rough estimate as
end of ear growth.
and finally as 65 describe 50% completion of anthesis, so this
is equal to Beggining of grain filling.
Correct me please if I am wrong.
