研究了水分胁迫对诸葛菜叶片的水分状况、渗透调节能力以及活性氧代谢的影响 .结果表明 :在水分胁迫下 ,诸葛菜叶片相对含水量 (RWC) ,自由水含量 (FWC)下降 ,束缚水含量 (BWC)上升 ;可溶性糖 ,脯氨酸 ,K+ ,Ca2 + 含量均出现明显的增加 ,具有一定的渗透调节能力 ;随着水分胁迫的加剧 ,O2 -产生速率增加 ,丙二醛 (MDA)积累 ,导致膜损伤 ,质膜透性上升 ,超氧化物歧化酶 (SOD)、过氧化物酶 (POD)活性均出现“先上升 ,后下降”的趋势 ,抗坏血酸 (AsA)含量则降低 ,表现出诸葛菜一定的适应性 . The effects of water stress on water status, osmotic adjustment ability and active oxygen metabolism of the leaves were studied.The results showed that RWC and FWC decreased under water stress, (BWC) increased; soluble sugar, proline, K + and Ca2 + content increased obviously, and had certain ability of osmotic adjustment; with the increase of water stress, the rate of O2 - Accumulation, leading to membrane damage and increased plasma membrane permeability. The activities of SOD and POD all increased first and then decreased, while the content of AsA decreased A certain degree of adaptability to Ge Ge.
