| Abstract: | Roots are an integral part of plant organs and involved in acquisition of nutrients and water,synthesis of plant hormones,organic acids and amino acids,and anchorage of plants.Root morphology and physiology are closely associated with the growth and development of above-ground part of plant.In this review,the relationships of root morpho-physiological traits with the formation of grain yield and the absorbtion of water and nutrients in rice were summerized.Recent advances in research on the role of the root... |
