摘要
研究了NaC l胁迫(0、50、100 mmol.L-1)下番茄‘沪番2560’(耐盐性较强)和‘沪番2608’(耐盐性较弱)植株生长、叶绿素含量、叶绿素荧光特性和渗透调节物质的影响。结果表明,NaC l胁迫明显降低植株生长、叶片叶绿素含量、PSⅡ潜在活性(Fv/Fo)、光化学效率(Fv/Fm),显著增加脯氨酸和可溶性糖含量。‘沪番2560’幼苗生长受盐胁迫的影响小于‘沪番2608’,其光合机构受盐胁迫的伤害程度小于‘沪番2608’。
The plant growth ,chlorophyll content ,chlorophyll fluorescence characteristics and osmotic adjust in tomato seedlings were studied under 0,50 and 100 mmol· L^ -1 NaCl stress. The results showed that the plant growth ,chlorophyll content and potental activity of PS Ⅱ （ Fv/ Fo） ,photochemical efficiency of PS Ⅱ （Fv/Fm） were decreased,contents of proline and soluble sugar were increased. The plant growth of ＇ Hufan2560＇ was less affected than ＇ Hufan 2608＇ and the photosynthetic apparatus was less injured than ＇ 2608＇.
