摘要

目的: 探讨太空诱导对丹参不同生长阶段的生理生化特性的影响。方法: 考察了航天搭载后丹参不同生长期叶片中的叶绿素、可溶性糖、可溶性蛋白的含量变化以及过氧化氢酶(CAT)、超氧化物歧化酶(SOD)的活性

并同时与地面对照组丹参进行比较。结果: 搭载后丹参的光合色素含量增加明显

花前期不同部位叶绿素含量平均增加28.5%

可溶性糖的含量平均减少近42%

且可溶性糖含量与叶绿素含量呈负相关;CAT

SOD的活力均高于地面对照组。结论: 航天搭载对丹参的光合特性和生理生化方面产生影响

能够显著提高其光合作用

增强CAT

SOD的活力。

Abstract

Objective: The effect of physiological characters of Salvia miltiorrhiza induced by space flight was studied. Method: The contents of soluble sugar

soluble protein

catalase(CAT) and superoxide dismutase(SOD) activities in S. miltiorrhiza induced by space flight were investigate and compared with the contrast lines of ground. Result: The content of photosynthesis pigment in S. miltiorrhiza induced by space flight was increased enormously

the content of chlorophyll increasing by an a verage 28.5% and the content of soluble sugar reduced by nearly 42% at different part in pre-flower period. The content of soluble sugar and the content of chlorophyll showed a negative correlation. Physiological enzyme activities of CAT and SOD were higher than the contrast lines of ground. Conclusion: Space flight has the influence to the photosynthesis and the physiological biochemistry of Salvia miltiorrhiza. Photosynthetic rate and enzyme activities of CAT and SOD were increased.
