Description

This code and dataset accompany the manuscript by Ingram et al., titled "Towards Understanding Apoplastic Freezing Under Negative Pressure". It includes branch freezing data from Pinus sylvestris branches under varying water potentials. Immersion freezing data can be found here: https://doi.org/10.57707/fmi-b2share.b0c1e8e4d15b472c8df10984fee85e8a
