Latent time of response to applied ethylene of four Poa spp. that naturally occur at different elevations

Species	Latent Time of Response
	Range		Average
	0.03 μL L−1	7 μL L−1	0.03 μL L−1	7 μL L−1
	min
P. alpina	7–13	10–15	10 ± 1	12 ± 2
P. compressa	15–19	10–16	17 ± 1	14 ± 2
P. annua	11–17	10–16	14 ± 2	14 ± 2
P. trivialis	11–30	10–15	20 ± 4	13 ± 1

Ethylene was applied at 0.03 (promoting effect in P. alpina and P. compressa) and 7 μL L⁻¹ (inhibitory effect in all the species). Range and average ± se are indicated (n = 4).
