| 摘 要： | 选择性状优良的单株肉苁蓉种子，经“实践八号”返回式卫星搭载进行空间诱变，回收后与未搭载的地面对照同时进行生活力水平和红外光谱特征分析，并在相同环境条件下接种于寄主梭梭根部，对诱变前后肉苁蓉种子的接种寄生情况进行调查。结果显示，与对照相比，搭载后的肉苁蓉种子生活力和接种寄生率均有显著提高，寄生芽体的腐烂率大幅度降低，说明空间诱变对肉苁蓉种子的生活力、发芽率和抗病性均有一定促进作用。红外光谱分析显示，太空搭载后肉苁蓉种子中的蛋白质和可溶性糖类含量增加，油脂类含量有所降低，蛋白质与脂类所在特征区域的峰高比(I1630／I1745) 由1.07增加到1.16，推断这可能与肉苁蓉种子生活力增强，萌发抑制物质减少有关，说明太空微重力和强辐射等因素导致了肉苁蓉生活力的改变，同时其物质代谢途径也发生了改变。 |

| Abstract: | The seeds of Cistanche deserticola which from a single plant with fine properties were carried to the space by the recoverable experiment satellite "Shijian No.8". After space loading, the seed viability and characters of infrared spectroscopy were analyzed and then planted to observe and investigate the variation and heredity. The results showed that compared to the control group, the seed viability and germination rate increased observably after space loading. As well, the plants grew much healthier at th... |
