研究了水分亏缺对鼠尾草地上部分的营养生长、脂肪酸和精油产量和成分的影响。植物采用不同程度的水分亏缺（C、MWD 和 SWD）进行处理。结果显示不同生长参数显着降低。干旱显着降低了叶面脂肪酸含量和双键指数(DBI)度。这后来主要是由亚麻酸比例的强烈减少和棕榈油酸的消失引起的。此外，中度缺水增加了精油产量（以干重计，以g/100 g表示），主要精油成分为樟脑、α-侧柏酮和1.8-桉树脑，在中度缺水下呈增加趋势。 (C) 2008 Elsevier B.V. 保留所有权利。
The effects of water deficit on vegetative growth, fatty acids and essential oil yield and composition of Salvia officinalis aerial parts were investigated. Plants were treated with different levels of water deficit (C, MWD and SWD). Results showed important reductions of the different growth parameters. Drought decreased significantly the foliar fatty acid content and the double bond index (DBI) degree. This later was provoked mainly by a strong reduction of linolenic acid proportion and the disappearance of palmitoleic acid. Besides, moderate deficit increased the essential oil yield (expressed as g/100 g on the basis of dry weight) and the main essential oil constituents were camphor, alpha-thujone and 1.8-cineole which showed an increasing under moderate water deficit.
