摘要
本文综述了近年来与作物对氮素养分高效吸收有关的根系形态学研究情况,简要比较了解释氮素供应诱导作物根系形态变化的几种观点,着重阐述了用氮素诱导碳水化合物定向分配来解释根系变化的合理性和意义,并提出了根系研究在水分、养分效率和植物营养遗传研究中的展望。
The paper summarizes recent progress in study on root morphology related to nitrogen efficient acquisition,and briefly compares different hypothesizes used to elucidate the phenomenon that root growth can be induced by nitrogen supply.Rationality and significance of applying the hypothesis that nitrogen may induce transport and allocation of carbohydrate thereby induce the growth of root are explicated here. Perspective of root research in the nutrient efficiency and plant nutrition hereditism is presented.
