Leaf Traits Explain the Growth Variation and Nitrogen Response of × and in Mixed Culture.

Mixed cultivation with legumes may alleviate the nitrogen (N) limitation of monoculture . However, how leaf functional traits respond to N in mixed cultivation with legumes and how they affect tree growth are unclear. Thus, this study investigated the response of leaf functional traits of × ( × ) and () to mixed culture and N application, as well as the regulatory pathways of key traits on seedling growth.
