Table 5. The effects of exogenous NAE and butanol on germination of cucumber and pea seeds during imbibitional chilling.

NAE in DMSO solvent and n- and t-butanol were applied to the seeds immersed in water at 4 °C for 24 h, which were then transferred to moistened paper at 25 °C and scored for their relative germination rate at seven days. Data are shown as mean ± SE (n = 4 replicates of 40 seeds each). Values in the same row with an asterisk are significantly different from that of control (Water) (P < 0.05).
