The effects of gas-plasma-activated water (Air GPAW) and GA biosynthesis inhibition on the time courses of Nicotiana tabacum testa rupture (TR) and endosperm rupture (ER). (a) Effect of the GA biosynthesis inhibitor paclobutrazol (PAC) and GPAW on TR and ER in continuous white light (ca. 111 µmol m⁻² s⁻¹). (b) The effects of GPAW, GA and PAC treatment on the TR and ER of tobacco seeds imbibed in darkness. Results are shown as mean ± SEM of three petri dishes each with 40 seeds imbibed at 20 °C.
