Abstract

Abstract: The growth and development of root system is one of major factors to effect wheat grain production. Observing wheat root growth and distribution on soil profiles by application of underground root observation boxes to define root system growth and development after wheat flowering has very important meaning for understanding formation of wheat yield and quality. The result of this study shows that the amount of root growth reaches its peak during wheat flowering stage, then, decreases on a linear trend. The distribution of root system on the soil profiles after wheat flowering is mainly within 60-120cm soil layers. Major root decrease zone is within 30-60cm, and has fastest speed during the day of 11/5 to 12/5.

Key words: Wheat, Roor system, Growth and development distribution
