Objective]Nitrogen( N) supply and container type have each proved to effectively regulate seedling quality. In this study, we tested if the combination of the two approaches couldimprove seedling quality and produce a superposition effect on seedling growthin order to provide a theoretical basis in the containerized seedling cultivation.[Method]Quercus variabilis,with a dominant taproot,was reared in two different depth containers(25 cm,36 cm) with application of either deficient(25 mgN·seedling -1) or luxury(100 mgN·seedling -1) nitrogen supply,in a two factors completely randomize design. Seedling growth,root characteristics,and nutrient concentration were measured at the end of the growth season. [Result]N supply and container depth were significantly interacted on root N concentration,root volume,andsurface area for medium-class roots(2. 0 展开▼
