- Intervention effect Light water stress did not significantly decrease Nei2you6 yield.
- Intervention effect Severe water stress reduced Nei2you6 yield by 15.2%.
- Intervention effect Soil water stress increased yield of Ⅱyou7954.
- Observation Nei2you6 was more sensitive to soil water stress than Ⅱyou7954.
- Intervention effect Light water stress slightly promoted superficial root growth.
- Intervention effect Severe water stress reduced superficial root dry weight of Nei2you6 by 10.5%~31.6%.
- Intervention effect Severe water stress reduced superficial root dry weight of Ⅱyou7954 by 13%.
- Intervention effect Soil water stress enhanced superficial root activity.
- Intervention effect Cutting roots at panicle initiation decreased grain number per panicle.
- Intervention effect Cutting roots at flowering decreased spikelet fertility rate.
