Aristolochia sp. germination using Gibberellic Acid?
I have been trying to get various Aristolochia species to germinate with no success. I have tried surface sowing, after soaking for 48 hours, in plug trays with a cover on a heat mat. I have tried soaking for 48 hours in hand hot water in moist paper towel inside a zip lock bag on a heat mat. I am now wondering about the effects of using Gibberellic acid on the seed while soaking them. Has anyone had any luck using the GA3 during the soak to break dormancy? At this time I am extremely frustrated......lol. Any help or instruction would be greatly appreciated.
