摘　　要：为探讨不同处理措施对核桃无融合生殖的影响,以"绿岭"核桃为材料,采用聚乙烯醇封柱头后用不同药剂涂抹子房的方法,研究了2,4-D、赤霉素、硼砂及综合处理后"绿岭"核桃的无融合生殖坐果率。结果表明:0.2%的硼砂、30 mg/L的赤霉素、0.3%硼砂+0.3%磷酸二氢钾处理的"绿岭"核桃无融合生殖坐果率分别为88.37%、86.57%、86.27%,均极显著高于对照,分别比对照提高了23.54%、21.74%、21.44%;15 mg/L 2,4-D处理的"绿岭"核桃无融合生殖坐果率为82.50%,显著高于对照,比对照高了17.67%。In order to improve the fruit setting of apomixes in ＂Lv Ling＂ walnut,the effect of 2,4-D,GA3,borax and comprehensive treatment on fruit setting of apomixes was studied with ＂Lv Ling＂ walnut whose stigma was treated with PVA.The results showed that the fruit-setting rate of 0.2% borax treatment,30 mg/L GA3 treatment and 0.3% borax with 0.3% KH2PO4 treatment was 23.54%,21.74% and 21.44%,significantly higher than that of control respectively（P0.01）.In addition,the fruit-setting rate of 2,4-D 15 mg/L treatment was 17.67% higher than that of control.
