摘　　要：以2个水稻品种J59和B9363及其转Bar基因株系TR5、TR6为材料,研究了除草剂Basta不同喷施浓度、喷施剂量及喷施时间对转基因水稻秧苗叶绿素含量的影响。结果表明:Basta浓度对转基因和非转基因水稻叶绿素含量影响差异较大,喷施剂量和不同施药时期对其影响次之。在两叶期喷施标准浓度(3.2 g/L)Bas- ta,2个转基因株系TR5和TR6均表现良好的耐药性,在三叶一心期,TR5的耐药性好于TR6。Through treatments of the two rice species J59 and B9363, and their transgenic products TRS, TR6 with Basta in different spraying time, concentration and dosage, we found that Basta had direct effect on the two species. The choice of spraying time and concentration played a key role. Compared with concentration, dosage is less important. The resistance to Basta of transgenic lines presents significant difference. TR5 is more resistant than TR6 whether in two-leaf and threc-leef-and-one-leaflest stage.
