Can lamina fresh mass be used to represent lamina dry mass? Evidence from Photinia serratifolia

Autor: Dan Yan, Yabing Jiao, Peijian Shi

Publikováno v: Frontiers in Ecology and Evolution, Vol 11 (2023)

Lamina dry mass (LDM) per unit area is an important plant functional trait. However, it is time-consuming to dry leaves in practice. Previous studies have demonstrated that lamina fresh mass (LFM) is approximately proportional to LDM for some broad-l
