I am trying to relate the growth stages in CERES-Wheat to Zadoks' scale, but I can't decide where the end of CERES-Wheat stage 2 and beginning of stage 3 should fall. I'm no expert in this, so my best guesses for the other stages may not be very good either.
CERES Description Zadoks?
----------------------------------------------------------------------------------------------
1 Emergence to terminal spiklet initiation 10 to ?
2 Terminal spiklet to end of leaf growth ? to 42
3 End of leaf growth to end of preanthesis
ear growth 43 to 59?
4 End of preanthesis ear growth to
beginning of grain filling 60 to 69
5 Grain filling 70 to 89
6 End of grain filling to harvest >90
Any suggestions or other guesses are appreciated. If someone has figured this out for the Haun or Feekes scale, that would work as well.
Thanks,
Ed Barnes
