摘  要:
用差时播种共培法的改进方法对 138份稻种资源进行了化感作用抑稗评价 .结果表明 ,江西的青困二号、江苏的吓一跳、安徽的鸡早籼、江西的赣早籼 37、陕西的商糯 1号、IRRI的IR6 84 6 5 2 3 2、韩国的水原 92对稗草表现出较强的化感抑制作用 .盆栽研究表明 ,谷梅 2号、中 15 6对稗草的抑制作用显著大于对照 ,而化感作用材料TN1对稗草的抑制作用与无化感作用材料秀水 6 3无显著差异 .中 15 6的抑制作用强与其株高与秀水 6 3有显著差异有关 ,而谷梅 2号对稗草的抑制作用强主要在于其本身具有化感作用特性 .

摘  要:
rice ( Oryza sativa ) germplasms were identified to study the allelopathy to barnyardgrass ( Echinochloa crus galli ),using the relay seeding technique .The results showed that Qingkun 2 from Jiangxi Province , Xiayitiao from Jiangsu Province ,Jizaoxian from Anhui Province, Ganzaoxian 37 from Jiangxi Province, Shangnuo 1, IR68465 2 3 2 from IRRI,and Shuiyuan 2 from Korea had a strongly excellent inhibition effect on barnyardgrass. Results from pot culture showed that Gumei 2 and Zhong 156 had a greater inhibitory effect than control, and allelopathic material TN1 had no significantly inhibition effect,compared to non allelopathic material Xiushui 63. The effect of Zhong 156 was related to its plant height, and significant different from that of Xiushui 63.Gumei 2 had a stronger inhibition effect on barnyardgrass,due to its own allelopathic trait.
