春化阶段小麦在发芽出苗以后,必须经过一定时期的低温影响,才能正常生长发育。这种特性叫春化特性,所经历的一定时期叫春化阶段。小麦品种由于春化阶段要求温度高低的不同,常分春性品种、半冬性品种、冬性品种三类。春性小麦品种通过春化阶段要求温度较高,经历的时间也短,一般5～15℃,时间5～15天。冬性小麦品种春化
The vernalization stage of wheat emergence after germination, must be a period of low temperature effects in order to normal growth and development. This characteristic is called the vernalization feature, which has undergone a certain period of vernalization. Wheat varieties as the vernalization stage requires different temperature levels, often divided spring varieties, semi-winter varieties, winter varieties three categories. Spring wheat varieties through the vernalization stage requires a higher temperature, experienced a short time, usually 5 ~ 15 ℃, time of 5 to 15 days. Winter wheat varieties vernalization
