Anne 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. Mohammad
