Effect of some priming treatments on germination of 4·5-year-old Stackhousia tryonii seeds

Treatments	Germination (%)	s.e.m.
Controls
Non-primed control*	23·3a	3·85
Primed control†	19·2a	3·59
Priming treatments
L + D + GA3 (150 μM)	17·8a	3·48
L + D + GA3 (300 μM)	18·3a	3·52
L + D + KCN (40 mM)	8·4c	2·48
L + D + KCN (80 mM)	9·3bc	2·62
L + D + Smoke water (5 %)	6·2c	2·14
L + D + Smoke water (10 %)	16·5ab	3·38

Values represent the mean percentage germination of four individual replicates of 15 seeds each under light and dark treatments.

^*Seeds were neither leached nor dehydrated.

^†Seeds were leached (L) in running tap water for 36 h and dehydrated (D) by spreading on a plastic tray for 20 d at room temperature (approx. 25 °C).

Means followed by the same letter are not significantly different (P < 0·05); s.e.m., standard error of mean.
