| Abstract |
Glufosinate, a special herbicide for the transgenic rice with glufosinate resistance , gave excellent control effect to Leptochloa chinensis, Rotala indica, Lindernia procumbens, Ludwigia prostrata, Eclipta prostrata, Paspalum distichum , Marsilea quadrifolia and Murdannia triquetra. However, it did not control Eleusine indica, Eleocharis acicularis, Eleocharis plantagineformis, and Alternanthera philoxeroides. The barnyardgrass emergenced early was killed but the weeds of cyperaceae and broadleaf weeds were not after being treated with glufosinate. The transgenic rice 9921 provided more filled rice grains per panicle. The transgenic rice Jiahe 201 didn’t affect the weed populations and their biological mass compared with the parent Bing 94202. R values as the factor on barnyardgrass were significantly higher given by the transgenic rice 9921 and Jiahe 201 than the allelopathy potential variety D-gu, and similar to the non-allelopathic rice Xiushui 11. It indicated that the transgenic rice 9921 and Jiahe 201 had not any competitive advantage of allelopathy compared with barnyardgrass. |
