The biomass of rice were not affected by partial-root water stress under those three nitrogen forms, but root parameters of sole nitrate supply decreased significantly under water stress compared to non-water stress part. Water stress stimulated the absorption of NO_3~--N. The photosynthesis rate was inhibited by water stress under NO_3~--N supply, but no effects under NH_4~+-N supply.

局部根系水分胁迫对3种供氮形态营养水稻总生物量没有明显影响，但对单供NO_3~--N营养水稻根系的生物量、根系总长、根体积、平均直径以及根表面积的影响最大，均以未受水分胁迫的一侧根系生物量明显高于另一侧。
