【目的】选育磷高效水稻材料是利用土壤磷资源的有效方式,根系是水稻吸收磷素最重要的器官,其形态结构特征直接影响水稻的磷素吸收能力,研究水稻根系发育特征有助于揭示其磷高效吸收的机理。【方法】采用水培试验,以40份水稻材料为研究对象,设置0.003 mmol/L(低磷)和0.3 mmol/L(正常磷)两个供磷处理,于分蘖期调查水稻地上部生物量和磷积累量,采用聚类分析筛选磷高效水稻材料。针对筛选获得的磷高效水稻材料R527和磷低效水稻材料IR58025,分析其根系形态和解剖结构特征,解析水稻根系发育特征与磷吸收的关系。【结果】1)低磷条件下,40份水稻材料磷吸收能力存在显著差异,生物量和磷积累量的范围分别为0.11~0.93 g/plant和0.07~0.58 mg/plant。以磷积累量为主、生物量为辅进行聚类分析,获得磷高效水稻材料R527和磷低效水稻材料IR58025。2)低磷条件下,磷高效水稻材料R527的生物量(0.83 g/plant)和磷积累量(0.46mg/plant)显著高于磷低效水稻材料IR58025,分别为IR58025的6.38和5.75倍。3)低磷条件下,磷高效水稻材料R527的总根长、根表面积、不定根长、侧根长和侧根表面积比正常磷处理分别增加了61.79%、38.12%、60.44%、67.99%和186.67%。低磷条件下,磷高效水稻材料R527的总根长、根表面积、根体积、平均根直径、不定根长、侧根长、不定根表面积和侧根表面积分别为磷低效水稻材料IR58025的2.62、2.87、3.22、1.18、4.41、2.97、3.97和1.45倍。4)低磷条件下,磷高效水稻材料R527中柱、外皮层和皮层占比分别为磷低效水稻材料IR58025的1.11、0.67和1.05倍。5)低磷条件下,水稻的总根长、根表面积、根体积、平均根直径、不定根长、侧根长、不定根表面积、侧根表面积、皮层占比和中柱占比与生物量和磷积累量显著正相关,外皮层和内皮层占比与生物量和磷积累量显著负相关。【结论】磷高效水稻材料R527的生物量和磷积累量均显著高于磷低效水稻材料IR58025。低磷条件下,磷高效水稻材料R527更大的总根长、根表面积、根体积、不定根长、侧根长、不定根表面积、侧根表面积和皮层占比,更低的外皮层和内皮层占比是其磷高效吸收的重要原因。
