丹参的根在中药中有广泛的用途。本研究旨在探讨干旱胁迫对丹参生长和活性成分的影响。在整个生长周期内，设置了3种水分胁迫处理，即对照、中度干旱和重度干旱。结果表明，干旱胁迫显著降低了丹参的地上部和根部干重，但增加了生长后期的根冠比。除迷迭香酸外，其余活性成分含量在水分胁迫条件下均呈上升趋势。水分胁迫显著增加丹酚酸B的产量，降低丹参酮IIA的产量。我们的研究表明，在半干旱和干旱地区改进或发展丹参栽培方法是可行的。皇冠版权所有(C)2010由爱思唯尔出版。保留所有权利。
The roots of Salvia miltiorrhiza Bunge are widely used in traditional Chinese medicine. The objective of this study was to investigate the effect of drought stress on growth and active constituents composition in S. miltiorrhiza. Three water-stress treatments, including control, medium drought stress and severe drought stress, were applied on the whole growth cycle. The results showed that drought stress significantly decreased both shoot and root dry weight in S. miltiorrhiza, but increased the root to shoot ratio at later growth cycle. Except rosmarinic acid the other active constituents content increased under water-stress conditions. Water stress significantly increased salvianolic acid B yield, and decreased that of tanshinone IIA. Our study suggests that it might be feasible to improve or develop S. miltiorrhiza cultivation methods under semi-arid and arid regions. Crown Copyright (C) 2010 Published by Elsevier B.V.
