中文摘要：

对加拿大披碱草×披碱草F1和加拿大披碱草×圆柱披碱草F1的幼穗外植体愈伤组织诱导及植株的再生进行了研究.试验筛选出2个杂交种愈伤组织诱导的最适培养基均为：MS＋400 mg/L CH＋3.0 mg/L2,4-D;最适继代培养基为MS＋400mg/L CH＋1.0 mg/L 6-BA＋0.5 mg/L 2,4-D;最适幼苗分化培养基为：MS＋400 mg/LCH＋3.0 mg/L6-BA＋0.5 mg/L NAA;最适生根培养基为：MS＋0.5 mg/L NAA＋0.5 mg/L IBA.这一组培体系的建立,为2个种间杂交种的种质保存及利用奠定了基础.

英文摘要：

The study investigated callus induction and plant regeneration of young spikes in hybrid F1 of Elymus canadensis × E. dahuricus and E. cylindricus. It found that for the two hybrids the optimal callus induction mediums were MS＋400 mg/L CH ＋3.0 mg/L 2,4-D,the optimal secondary mediums were MS ＋400 mg/L CH ＋1.0 mg/L 6-BA＋ 0.5 mg/L 2,4-D, the optimal mediums of plantlet differentiation were MS＋400 mg/1. CH ＋3.0 mg/L 6-BA＋ 0.5 mg/L NAA and the optimal mediums for rooting were MS＋ 0.5 mg/L NAA＋0.5 mg/L IBA. This tissue culture system laid a foundation for germplasm conser- vation and exploitation of the two interspecific hybrids.
