Abstract: According to the result of ecological research on the winterness wheat sowing at autumn from 1982 to 1985 in Guiyang and Beijing, The northern winterness wheat varieties could pass through vernalization and maturity normally at autumn sowing in different date. This experiment also indicated that the northern winterness wheat could pass through vernalization within a more wide lower-temperature when the condition join short-day photoperiod in winter season. Short-day accelerated vernalization process for winterness wheat. The duration of northern winterness wheat in Guiyang is more shorter than in Beijing and some characters of northern winterness wheat in Guiyang is also superior to Beijng. Such as these characters povide sientific basis for make rational use northern winterness wheat resource in Guizhou.
