摘　　要：以8个不同类型花生品种为试验材料,在人工控水条件下,于播种后60d给予干旱处理,调查干旱及正常供水对照的结荚数及其着生节位,揭示干旱对花生荚果空间分布的影响。结果表明,高节位分枝及高节位结荚少,占单株荚果总数比例小的品种抗旱性强。山花11号高节位分枝及高节位结荚少,占单株荚果总数的比例小,抗旱性强;ICG6848、白沙1016、ICG6848和莱宾大豆高节位分枝或高节位结荚较多,占单株荚果总数的比例大,抗旱性弱。With 8 peanut （Arachis hypogaea L） cultivars of 5 botanical types grown under the artificial water control condition, which applied the drought treatment on the 60th day after sown. Investigation was executed on the number of pods and its nodes under normal water and drought stress to reveal the influence of the drought on the spatial distribution of peanut pods. The results showed that the peanut varieties with less pods on the high section branch and high section had better ability to resist drought. Shanhuall had more pods on the low section branch and low section, it was stronger to resist drought. Baishal016, ICG6848 and Laibindadou had more pods on the high section branch and high section, so they were poor to resist drought.
