Raw growth measurement data for triploid Betula platyphylla clones in Fusong County from 2020-2022

This dataset contains the raw growth measurements from a field trial of triploid Betula platyphylla clones established at Fusong County, Jilin Province, China in 2024. The trial followed a randomized complete block design with 4 replicates. Measurements for tree height (H, m), ground diameter (GD, mm), stem form straightness index (FSI), and survival rate (SR) were conducted at 1 year after planting (May 2025). The Excel file contains two sheets: “Growth_Data” (the primary measurements of H, GD and FSI for all individuals) and 'Survival Rate' (plot-level survival rate data for each clone in each block).
