Abstract

The development characteristics, spike differentiation processes and winter killing of three varieties of wheat were studied in the different sowing stages. The results showed that the stronger the springness of wheat was in earlier sowing stages, the quicker it developed and the higher spike differentiation phases it reached before the over wintering and the more serious winter killing it suffered from in winter. If it was at the double ridge phase during the over wintering, the risk of being winter killed was lower. By these, the safe sowing time of different wheat were put forward.
