Abstract:

利用开顶式气室研究了臭氧浓度升高对水稻(OrazasativaL.)生长的影响及外源抗坏血酸(ExogenousAscorbicAcid)的防护作用。臭氧处理共设4个水平:空气NF(No-Filter,臭氧浓度约20~50nL·L-1)、过滤CF(Charcoal-Filter,臭氧浓度约为5~15nL·L-1)、臭氧Ⅰ(8h平均100nL·L-1)、臭氧Ⅱ(8h平均200nL·L-1),外源抗坏血酸浓度设置为0.1%(m/V)。结果表明,与NF处理相比,高浓度O3(200nL·L-1)处理会造成水稻叶片的叶绿素a、水稻的株高、叶面积、穗粒数及粒重,分别下降了47.9%、17.8%、31.6%、45.7%和42.9%;喷施外源抗坏血酸后,与各自的对照相比,以上各生长指标分别上升了11.6%、7.7%、17.4%、5.6%、11.1%。可见外源抗坏血酸能有效缓解O3对水稻的胁迫作用,提高了水稻对O3的抗性,促进水稻的生长。
