Beneficial Effect Ga3 is a naturally occurring plant growth regulator which may cause a variety of effects including the stimulation of seed germination in some cases. GA-3 occurs naturally in the seeds of many species.Presoaking seeds in GA-3 solution will in many cases cause the rapid germination of many types of highly dormant seeds which would otherwise need cold treatment, after-ripening or ageing, or other prolonged pretreatments.
take 0.1g of GA3 powder and dissolve in about 5ml of 70% rubbing alcohol. After it is dissolved just add this solution to 95ml of water. Now let stand for about 2 hours.
The solution you just prepared is 100ml of a 0.1% solution of GA3.
You dont need much of this solution for soaking your seeds. Just take a filterpaper put your seeds into it, put seeds and filterpaper into a polybag and moisten the paper and let seeds soak for 12-24 hours.
You don't need much of the solution to soak your seeds, just enough for the seeds to fully swell. Most seeds can be soaked in the small poly-bags. Tiny seeds should be folded up in a filter paper for ease of handling when soaking. Larger seeds can be soaked in a pill bottle or small jar. - See more at:
