以星油藤为材料，研究在干旱胁迫环境条件下，星油藤生理的变化规律，结果表明：随着干旱胁迫程度的加深及时间的延长，叶片相对含水量、叶水势、叶绿素含量逐渐降低，膜透性、MDA、可溶性糖、脯氨酸含量逐渐升高，质膜受到损害，可溶性蛋白含量呈从低到高的增加趋势，SOD活性呈从高到低的降低趋势。在干旱胁迫下，星油藤的生理指标互相协调作用，存在显著的相关关系。%The physiological variation law of characteristic oil plant Plukenetia volubilis Linneo under the condition of drought stress was studied .The results showed that:when the extent of drought stress deepened ant its duration lengthened , the leaf relative water content , leaf water potential and leaf chlorophyll content of Plukenetia volubilis decreased gradually , the membrane permeabili-ty, malondialdehyde (MDA) content, soluble sugar content, and proline content increased gradually , the plasma membrane was damaged, the soluble protein content displayed a trend from low to high , and the activity of superoxide dismutase (SOD) displayed a trend from high to low .Under drought stress , the physiological indexes of Plukenetia volubilis had a coordinating interaction , and there were certain significant correlations among these indexes .
