水稻根系生长特性及其与地上部分关系的研究进展

Research Advance on Relation of Aerial Part and Root Traits of Rice

文章叙述了水稻根系的形态特征、功能与活力、根系与地上部分及产量的关系以及环境因子对根系的影响,分析了根系的生长发育特性及对水稻品质和产量的影响,得出水稻根系通过自身以及环境因素的影响对水稻品质及产量做出不同的响应。分析表明,加大对水稻根系指标的研究,加强现代分子生物学技术在水稻根系方面的研究,完善根系研究的方式方法,对水稻进一步取得高产以及生产上的指导具有重要意义。

The research overviews the morphology of rice roots,functions and vigor of rice roots,relationshipsbetween rice roots and aboveground parts and yield,and the impact of environmental factors on roots,andanalyzes the impact of root growth and characteristics on quality and yield of rice,concludes that rice rootsrespond differently to the quality and yield of rice through itself and the impact of environmental factors.Theanalysis shows that it is of great significance to carry out more research on the root index of rice,strengthen theresearch of modern molecular biology techniques in rice roots,and improve roots study,in order to providefurther guidance rice production.
