摘要: 摘 要 提取液中添加10 mg/L秋水仙碱可提高大麦小孢子游离后的存活率;以含10 mg/L秋水仙碱的预处理液预处理小孢子48h可以降低培养72h后小孢子的死亡率;以小花共培养可以提高正常型多细胞结构形成率,因而明显提高胚状体的形成。

Abstract The frequency of survival isolated microspores could be increased by adding colchicine 10 mg/L to isolation solution. The frequency of dead microspores after 72h culturing could be decreased by pretreatment of freshly isolated microspores with isolation solution supplemented with colchicine 10 mg/L for two days. The productions of multicellular structure and embryo-like structure were improved by co-culturing with florets of barley.
Key words Barley; Microspores culture; Colchicine: Co-culture with florets
