| 摘要: |
| 用合成的新哒嗪类化合物９４０３，以ｆｅｎｒｉｄａｚｏｎ－Ｋ为对照，进行了９４０３对小麦的去雄效应的研究，试验结果表明９４０３对品种农大３３３８及北农２号的去雄效应与ｆｅｎｒｉｄａｚｏｎ－Ｋ相似，平均去雄率为９８．０％，与ｆｅｎｒｉｄａｚｏｎ－Ｋ（９８．２％）差异不显著，但９４０３对籽粒的影响程度比ｆｅｎｒｉｄａｚｏｎ－Ｋ小；平均人工粉结实率为８９．４％，显著高于ｆｅｎｒｉｄａｚｏｎ－Ｋ（８１．０％ |

| Abstract: |
| A new pyridazine compound 9403 was synthesized and its hybridizing activity for wheat compared with fenridazon-k were studied. The results indicated that 9403 has similar chemical hybridizing activity as fenridazon-k for two wheat cultivars BAU3338 and Beinong 2. The mean male sterility rates induced by 9403 and fenridazon-k were 98.0%and 98. 2% respectively with no significant difference. The mean artificial fertility rates were 89. 4% and 81.0% respectively with significant difference at 5% level. The mean weight of 1000 grains obtained by artificial fertilization were 27. 6 g and 26.0 g respectively with significant difference. Based on the analysis the proper dosage and treating stage of using 9403 was also determined. |
