【摘要】 以缺氧还原、矿质营养失调和水土温度低为特征的潜育性水稻土是我国南方稻区最主要的低产土壤类型之一。亚铁毒害、H2S毒害及有机酸毒害及矿质营养元素钾、磷、钾、锌缺乏是其主要胁迫因子。本文从比较生理生态角度综述了水稻对上述胁迫因子的耐性机制及基因型差异,并展望了通过遗传改良来提高水稻耐性的前景。
【Abstract】 Mechanism of rice(Oryza sativa L.) tolerance to mineral nutrition disorders(e.g.Fe++toxicity,H2S toxicity,organic acids toxicities,P.K. Zn and Si deficiencies) and gleyic paddy soil stress and varietal differences of rice tolerance to the stresses were seperatively reviewed.The prospect of rice stress-tolerance ecobreeding and utilization of tolerant genotypes were given in this paper.
【Key words】 rice(Oryza sativa L); gleyic—paddy soil; physio-ecological mechanism; varietal difference;
