The research status of plant root exudates

For plants,it has root secretion attune of nutrition effect,the specificity secretion of plant nutrition is adjust action the most outstanding secretions.The root of the secretion of poison of the cluster components may lead to the occurrence of continuous cropping obstacles,its allelopathy to play a curb on certain level the role of weeds.Meanwhile,because of the secretion of root,the quantity of soil borne microorganism in rhizosphere soil is much more than the quantity of that in un-rhizosphere soil under the root exudates,which in some extent normal growth of plant.Based on the classification of root exudates as the breakthrough point,discusses the root exudates research methods,from the plant growth,minerals,natural environment,heavy metals from four aspects: the influence factors of root exudates produced,and finally to the root secretion in agriculture and environmental applications are discussed,in order to root exudates research provides the certain reference and reference.
