Title: Gibberellic Acid and Seed Germination.
Post by: New Wisdom on July 06, 2013, 09:14:00 AM

I recently got some GA3 (Gibberellic acid) after reading about seed germination rates increasing with the use of this chemical.  I thought that I would share it with you all since it raised my germination rate from 1/5 to 4/5 with my L. williamsii.  I soak the seeds in a 100ppm solution of GA3 and distilled water before putting them on the germination substrate.

Here is an article on lettuce seed germination and GA3.

And another article (requires purchase, but has a description) on Trichocereus germination and GA3.

Thank you NW, much appreciated.

It's also worth mentioning that GA3 is used for more than seed germination. It can promote faster stem and root growth, and is often applied to increase production of mass in commercial cultivation, and to speed up growth.

Cheers,

Mandrake
