I've been having a play around with this auxin and nitrozyme as germination promoters.

Has anyone else tried using IAA to aid germination? I had some musa velutina seeds left over from last year and as all my plants died over winter I'd have a go at germinating some.

I soaked a batch in water for 48 hours then I split the batch into 2 and one half I soaked in nitrozyme 1ml/l and the other I soaked in 75ppm IAA for 24 hours.

I planted them and hoped for the best, the seed is a year old so I wasn't expecting much. To my surprise 4 of the nitrozyme seeds germinated within 3 weeks (2 died, damping off, grrrrr). I have just noticed that 5 of the IAA soaked seeds have sprouted a week later.

I had no control so this isn't a scientific study, but I'm definately going to try it again with some other seeds.

The acetic form (compared to Indole Butyric) is preferred as a penetrant for hard shelled seeds. More generally, acetic chelates are used when immediate penetration is desired in foliar sprays. In California, an important example is carbohydrate and potassium foliar sprays for commercial strawberry fields.
