中文摘要：

用不同浓度的聚乙二醇-6000（PEG-6000）溶液处理7个品种的小黑麦种子，测定其发芽率，发芽指数，活力指数、胚根、胚鞘、胚芽长度。结果表明，低浓度PEG-6000对小黑麦种子萌发有促进作用，随着胁迫浓度的增加，对种子萌发的抑制作用明显增强。不同品种表现不同，其中中新830最耐旱，中饲828、中饲237抗旱能力较强，冀饲1号、冀饲2号、NTH1048、NTH1888耐旱程度中等，劲松49为干旱敏感品种。

英文摘要：

The seeds of 7 triticale cultivars were treated with different the germination percentage, germination index, vigor index, length of showed that lower PEG concentration had a stimulating the inhibitive effects on the seed germinations obviously concentrations PEG-6000, then examined seedling, coleoptile and root. The results effect on the germination. As PEG concentration rose, increased. The different triticale euhivars were inhibited with different degree. The drought tolerance of ZHONGXIN 830 was the strongest,the drought resistance ability of ZHONGSI 828 ,ZHONGSI 237 were stronger, JISI 1 ,JISI 2 ,NTH 1048 and NTH 1888 were medium. JINSONG 49 was drought-sensitive cultivar in all cultivars.
