【摘要】 在温室盆栽试验中 ,评价抗草铵膦转基因水稻品种 99- 1不同叶期对该药的抗性。与非转基因水稻品种越富比较 ,该转基因品种对草铵膦具有较强的抗性。但不同叶期的抗性存在差异 :2叶期的抗性较差 ,1~2 kg.hm-2草铵膦处理时药害较严重 ,生长明显抑制 ;4 - 8叶期的抗性明显增强 ,中毒症状轻 ,即使在高剂量2 kg.hm-2 处理下 ,生物量的积累也不受影响。不同生育期 bar基因表达量、谷氨酰胺合成酶活性变化与抗性的关系尚需深入研究

【Abstract】 A greenhouse experiment was conducted to evaluate the resistance of glufosinate resistant transgenic rice cultivar 99 1 to glufosinate. The glufosinate resistant transgenic rice 99 1 was highly resistant to glufosinate compared to nontransgenic cultivar Yuefu. Howe ver, there were differences in the resistance to different herbicide rates among different growth stages. Plant height and biomass of the 2 leaf seedlings were significantly inhibited at 1.0 to 2.0kg·hm -2 glufosinate. The 4 to 8 leaf seedlings had higher resistance to any of the herbicide rates. Neither of the above ground nor the under ground biomass was reduced even at the highest rate of 2.0kg·hm -2 . The relationships of bar gene express to the degree of resistance, the amount of glutamine synthase at different stages of the transgenic rice cultivar, and the effect of environmental conditions on the resistance are being further studied.
