Differences in Water Consumption of Wheat Varieties Are Affected by Root Morphology Characteristics and Post-anthesis Root Senescence.

ABSTRACT: Selecting high-yielding wheat varieties for cultivation can effectively increase water use efficiency (WUE) in the Huang-Huai-Hai Plain, where is threatened by increasing water shortages. To further identify the difference in water use and its relationship with root morphology and senescence characteristics, wheat varieties with different yield potentials-Yannong 1212 (YN), Jimai 22 (JM), and Liangxing 99 (LX)-were studied in a high-yielding wheat field. The water consumption percentage (CP) in YN decreased from planting to anthesis; however, crop evapotranspiration and CP increased from anthesis to maturity compared with JM and LX. In YN, a higher soil water consumption from anthesis to maturity in the 0-100 cm soil layer was partly attributed to the greater root weight density in the 20-
