Summary of RNA integrity results for seeds from each species and harvest year used in the refrigerator experiment, in which seeds were stored at 3–5 °C and 35–50 % RH. Average RIN values ± s.d. from five independent samples are reported from assays performed in 2017. Each sample included one to five seeds, or a seed fraction, depending on species
