| 摘 要： | 以南农99-6为材料,通过盆栽试验研究了淹水胁迫(水面淹至大豆子叶节部位)对大豆生长与产量的影响。结果表明:淹水抑制了大豆的生长,随淹水时间延长大豆的主、侧根逐渐腐烂,茎淹水部分产生大量不定根,为大豆适应淹水环境提供条件。在淹水处理0~10 d内,植株的生物量、叶面积、光合参数较对照有一定增加,但10 d以后随时间延长呈下降趋势;叶片中的色素含量降低,随时间延长与对照差异显著;叶片丙二醛、过氧化氢含量随胁迫时间延长呈上升趋势,显著高于对照。淹水胁迫最终导致单株荚数和产量明显降低,淹水时间越长,降低幅度越大。综合各指标来看,光合参数、丙二醛和过氧化氢含量等生理指标在0~10 d与对照差异不显著,而10 d后差异显著,可以推断该大豆品种的淹水胁迫临界期为10 d。

| Abstract: | Effects of flooding stress on growth and yield of soybean(Glycine max var.Nannong99-6)was studied by pot experiment.The results showed that flooding stress(water level up to cotyledon node of soybean)inhibited the growth of soybean.The main roots and lateral roots of soybean gradually decayed with prolonging of flooding time.Adventitious roots produced from the flooded part of stem,which helped soybean to adapt to flooding environmental conditions.Biomass,leaf area,photosynthetic rate(Pn),and other photosyn... |
