| 摘 要： | ０．０１～１０ｍｇ／Ｌ的ＩＰＴ能够促进稻苗种子根侧根原基的数目。与此同时,种子根的内源激素ＩＡＡ和ＡＢＡ的含量显著提高,而ｉＰＡｓ的含量下降。ＩＰＴ处理后,种苗种子根的吲哚乙酸氧化酶（ＩＡＡｏｘ）的活性下降,过氧化物酶（ＰＯＤ）的活性上升。 |

| Abstract: | Treated with IPT (isoprothiolane )in 0.01,0.1,1.0,10 mg/L concentrations. respectively,the seminal root of rice seedling developed lateral root primordia 1.28-1.80 times higher in number than the control.Meanwhile,the contents of IAA and ABA in seminal root of rice seeding increased,but iPAs decreased.IPT decreased IAA oxidase(IAAox)activity of seminal root significantly,although enhanced POD activity slightly. |
| Keywords: | IPT Rice seeding Lateral root primordia Sulfur containing germicide |
