Title: Effect of Transgenic Rice with Glufosinate-Resistance on Weed Populations in Paddy Field
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 plntagineformis, and Alternanthera philoxeroides. The barnyardgrass emergenced early was killed but the weeds of cyoeraceae and broadleaf weeds weren′t after being treated with glufosinate. The transgenic rice ‘99-1’ 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 ‘94-02’. R values as the factor on barnyardgrass were significantly higher given by the transgenic rice ‘99-1’ 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 ‘99-1’ and Jiahe 201 had not any competitive advantage of allelopathy compared with barnyardgrass.
