摘要:
玉米(Zea mays L.)是重要的粮食作物和饲料作物。近年来,干旱对玉米的生产构成严重威胁。以玉米毛状根再生植株为试验材料,分别进行干旱胁迫4、6、8 d以及分别复水4、8 d的试验处理,研究玉米毛状根再生植株叶片光合特性对干旱胁迫和复水条件的响应规律。结果如下:随着干旱胁迫程度增加,毛状根植株和对照组植株的净光合速率(Pn)、气孔导度(GS)及叶绿素含量(SPAD值)呈下降趋势,细胞间隙CO2浓度(Ci)呈先下降后上升趋势,水分利用效率(WUE)呈先上升后下降趋势,干旱胁迫6、8 d,毛状根植株受影响较小,各光合指标显著高于对照组植株(P<0.05)。毛状根植株干旱胁迫8 d的SPAD值、PnGS与对照组干旱胁迫6 d的SPAD值、PnGS相当,干旱胁迫 4 d,差异虽不显著,但趋势相同。说明毛状根植株有较强的光合能力及耐旱性。随着复水天数增加,不同干旱胁迫处理的毛状根植株和对照组植株生理生化水平逐渐恢复,甚至干旱胁迫4 d处理的毛状根植株的GS出现了超补偿现象,干旱胁迫6、8 d处理的毛状根植株恢复良好,均显著高于对照组植株(P<0.05)。对照组植株除干旱胁迫4 d能恢复至接近正常供水水平外,干旱胁迫6、8 d处理恢复较难。结果表明,玉米毛状根再生植株光合能力强,这是由于其具有强大的根系,所以其对干旱的抵抗能力强,旱后复水的恢复能力显著。
