Replication data for: One leaf for all: Chemical traits of single leaves measured at the leaf surface using near-infrared reflectance spectroscopy

NIRS-based estimates of foliar chemical traits using two approaches. From NIRS-scans of dried, milled and tableted leaves and from NIRS-scans of full leaves dried flat.采用两种方法开展基于近红外光谱（Near-Infrared Spectroscopy, NIRS）的叶片化学性状估算。其扫描数据来源于两类样品的近红外光谱扫描：经干燥、粉碎并压片处理的叶片，以及平铺干燥的完整叶片。
