Seed conductivity measurements
Conductivity measurements were performed according to Brunel-Muguetet al. (2015). For each treatment (n=4 plants), measurements with
the electrolytes were made with 20 pre-weighed seeds. At room
temperature (20ÂșC), the seeds were placed in 5 mL of ultrapure water for
16 hours. Conductivity was measured with a portable electrochemical
analyzer (Consort C931, UK).
