Unlock the Walnut: How a Pectin-Rich Suture Tissue and Moisture-Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination

This dataset contains raw data presented and discussed in the paper: Antreich, S.J., Xiao, N., Felhofer, M., Gierlinger, N. (2025) Unlock the Walnut: How a Pectin-Rich Suture Tissue and Moisture-Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination. Advanced Functional Materials. e10682. https://doi.org/10.1002/adfm.202510682 The excel-file shows raw data on cell size and swelling behavior of walnut shell and suture tissue as well as data on crack lenght from cycling humidity experiments. Tif-files show picture stacks of the dry state form cycling humidity experiment where cracks occured. Raman spectra presented in the paper will be made available at MicrobioRaman at https://www.ebi.ac.uk/biostudies/microbioraman/studies. See also Lee et al. (2024), doi:10.1038/s41564-024-01656-3.
