Based on the growing stages data of winter wheat and contemporaneous temperature data from 1991 to 2010,the relationship between growing stages and temperature was studied in order to reveal impact of climate warming on growing stages of winter wheat in Southwestern Shandong Province. The results showed that: (i) the average temperature in the winter wheat growing stages form 1991 to 2010 increased significantly at a rate of 0. 57℃/10a,which were the most distinct during winter and spring, the sowing,wintering and greening were delayed by the ratio of 4. 083/10a,4. 018/10a,3. 519/10a; the jointing,heading and maturity of winter wheat were all advanced by the ratio of 1. 88/10a,2. 647/10a,1. 985/10a, respectively. (ii) The whole growing stages was shortened by 5. 865d/10a and the sustained days of sowing-wintering,wintering-greening, greening-jointing and jointing-heading were all shortened,while heading-maturity was prolonged by 0.662/10a. (iii) There was significant negative correlation between other growing stages and temperature while positive correlation between wintering and the temperature in November and December were observed,especially there was a very significantly negative correlation between jointing-heading and temperature. The sowing and greening all did not reach significant level. There was bigger correlativity between maturity and accumulative temperature form March to April. (iv) The impacts of climate warming on growing stages had both positive and negative, so the corresponding cultivation and management measures in the practical production sould be taken.
