Seed conductivity
Seed conductivity values ranged from 0.66 µS/mg DM to 2.86 µS/mg DM with
the mean HS and LS values being 1.43 and 1.27 µS/mg DM, respectively
(Table 3). No effect of S supply was observed, whereas a highly
significant T-modality effect was observed (p<0.001 ).
For both S supplies, extreme values were observed in T-control seeds
(lowest values) and in mod1 seeds (highest values). While no significant
differences between control, mod2, mod3 and mod4 were observed under LS,
different values were observed under HS with mod1 values being the
highest (around 228.7% of the T-control) followed by mod2 (47.1%).
This indicates that seed conductivity is highly responsive to the
duration and the earliness of the stressing period because seeds from
mod3 and mod4 that underwent the latest and shortest stressing events
are the least negatively impacted.
