looks like no-one ha experimented with it yet.. i was curious to see what would turn up..

are you thinking of it?

I'm going to use some for germination 200-500 parts per million for seeds.
ordered some from Gibberellic Acid

Keep us posted.You got me wanting to know more.I have heard that it is supose to produce females or more high female rate. Peace

well the use of hormones is not new to botanical science... this one is suposed to work perfectly if used in the proper manner. i have been concerned about reading that many of our growers are having males in their fem seeds. i think this is due to breeders cutting corners to speed up results, using maybe hermies to produce'fem' seeds , and basically not knowing whAT THEY ARE DOING. FEM SEEDS HAS become all the hype so obviously as with any high value illegal commodoty people want to cash in...

lets see your results. i too am extremely curious as to your results. its suposed to be the only sure fire way of getting fem seeds.

but try something before you do start (if you have room and pacience)... stress out your fems and weed out the ones that hermie too fast. this will result in you having only true females. (why you may ask? its because i believe that todays comercial seeds are watered down with alot of hermie genetics in there from greedy or just plain lazy breeders that cut corners in the dash for quick results.)

ask any breeder, real breeding takes pacience and pacience... and then some.
and like any science experiment you take the long scenic route to the end not the shortcuts.. remember to take notes

anyway, whatever you chose to do, i'll be curiously looking over your shoulder..

wish you a successful experiment

Sannie's version of Gibberellins

1898
Gibberellins were discovered by Japanese plant pathologists studying "bakanae" disease ("foolish seedling") of rice, in which seedlings grow elongated and die.

Instruction sheet that came with my GA3.
Gibberellic acid (pronounced "Jib - er - iIIic") is a very potent hormone whose natural occurrence in plants controls their development. It was first discovered in Japan in 1935 as a result of a study of "Foolish Seedlings Disease" which caused rice plants to grow much taller than normal.
With very small amounts, Gibberellic Acid (GA) can enhance normal growth and quickly produce much larger, greener plants. At moderate concentrations (sprayed on seeds) GA can have a surprising effect on their development and growth.
Some will germinate at a highly increased rate, other varieties of seeds will begin to grow much differently than untreated seeds. Still other seed varieties will produce only slight changes in development.
As the amount of Gibberellic Acid is increased, the change in plants becomes quite remarkable. At higher concentrations, plant growth becomes almost uncontrolled, producing incredibly large 'mutated' looking plants that have little resemblance to the original plant. Some will grow so tall, so fast, that the stalk will not support the plant and some sort of wooden or metal support will-have to be fashioned to prevent plant from falling over and breaking.
In a well-known Department of Agriculture experiment, Walnut trees were treated with small concentrations of Gibberellic Acid. In one season, the growth rate for the control group (the untreated trees) was 1.5 feet.
For the trees treated with Gibberellic Acid, growth averaged 8.5 feet.
We recommend using Gibberellic Acid in 3 different concentrations, depending on what you want to accomplish.
Please note that the recommended concentrations should be used as a starting point. Each different variety of plant will respond differently, and you will have to adjust the amount of GA to higher or lower levels as needed.
The Gibberellic Acid supplied is at a concentration of 1,000 ppm.
Pouring the concentrate into the spray bottle up to the % mark, and filling the remainder with water will give you a concentration of 250 ppm. Filling the spray bottle up to the %mark and filling the remainder with water will yield a concentration of 500 ppm. You can of course mix it to any concentration desired, but we have seen little success at concentrations under 150 ppm. .
Depending on the particular type of plant ,very high concentrations will begin to have a reverse effect and begin to interfere with plant growth. Only experimentation will reveal the ideal amount to use on your particular plant and in its particular stage of growth.
For seeds, we recommend spraying a paper towel until damp with a 250 ppm to 500 ppm solution, folding it over and placing your seeds in between. Keep the paper towel/seeds damp, and in the dark. When the seeds begin to sprout in several days, plant them in soil.
Plants in various stages of growth can be sprayed directly, or small amounts can be added to the soil. Spraying the plant directly seems to always yield the best results.
Gibberellic Acid is most effective in the early stages of plant growth, so the best results will be obtained using seeds, or very small seedlings.
Gibberellic Acid is ideal for a variety of science fair experiments/demos using a 'control' group of seeds that are grown normally and an identical group that are sprayed with Gibberellic Acid. Fascinating experiments can be performed using groups of plants treated with varying Gibberellic Acid concentrations.

I got the Gibberellic Acid kit in record time, there are a few ways he gives you to soak your seeds.
The instructions seem simple and straight forward and he gives a sheet on the history of GA also.
You use the stronger 1000 PPM solution on stubborn seeds and the 500 PPM on the younger or healthier seeds.
Here is a set of photos of the kit content.

its used on the seeds?

i thought it was used on growing tips...
how do you know you are reversing the sex of a female if your using it on seeds?

Kit plus shipping was only $22.50

That is very reasonable.

Just so you know, be very careful with that stuff.

You don't want it feminizing you buddy!!!!

ROTFLMAO! Sorry, couldn't resist! That door was pretty open!

I have heard it can be carcenogenic so be careful.

I've read it can be toxic, don't know what "feminizing you buddy"

I do love girl

that surely cant be right.
is that what it says on the bottle? ...


...i'll be back...

Gibberellic Acid for Fruit Set and Seed Germination

John M. Riley

The following information is taken from a article by John M. Riley that appeared in the 1987 CRFG Journal (vol. 19, pp. 10-12). See the back issue information for price and ordering information. The Germination Process

The first stage of germination consists of ingesting water and an awakening or activation of the germ plasma. Protein components of the cells that were formed as the seed developed, became inactive as it matured. After an uptake of water, the system is reactivated and protein synthesis resumes. Enzymes and hormones appear and begin to digest reserve substances in the storage tissues and to translocate the digested substances in the storage tissues to the growing points of the embryo. The sequence of the metabolic pattern than occurs during germination involves the activation of specific enzymes at the proper time and regulation of their activity. Control is exercised by four classes of plant hormones: inhibitors such as abscissic acid which block germination; auxins which control root formation and growth; the gibberellins which regulate protein synthesis and stem elongation; and cytokinins that control organ differentiation. Ethylene is also believed to have a control function in some plants. Sometimes the last three controls are used together to crash through dormancy in germinating difficult seed.
Gibberellic Acid

Gibberellic acid (actually a group of related substances called gibberellins) was discovered as a metabolic byproduct of the fungus Gibberella fujikuroi, which causes the stems of growing rice to elongate so rapidly the plant collapsed. Synthetic forms of gibberellic acid are available commercially. Gibberellic acid (GA) is a very potent hormone whose natural occurrence in plants controls their development. Since GA regulates growth, applications of very low concentrations can have a profound effect. Timing is critical: too much GA may have an opposite effect from that desired; too little may require the plant to be repeatedly treated to sustain desired levels of GA.
Effects of Gibberellic Acid

1. Overcoming dormancy. Treatment with high concentrations of GA is effective in overcoming dormancy and causing rapid germination of seed. Concentrations of about 2 ppm can cause tubers to sprout earlier.
2. Premature flowering. If a plant is sufficiently developed, premature flowering may be induced by direct application of GA to young plants. This action is not sustained and treatment may have to be repeated. Formation of male flowers is generally promoted by concentrations of 10 to 200 ppm., female flowers by concentrations of 200 to 300 ppm. Concentrations of more than 600 ppm markedly suppresses initiation of both male and female flowers.
3. Increased fruit set. When there is difficulty with fruit set because of incomplete pollination, GA may be effectively used to increase fruit set. The resulting fruit maybe partially or entirely seedless. GA has increased the total yield in greenhouse tomato crops both as a result of increased fruit set and more rapid growth of the fruit.
4. Hybridizing. Pollination within self-incompatible clones and between closely related species may some times be forced by the application of GA and cytokinin to the blooms at the time of hand pollination.
5. Increased growth. GA applied near the terminal bud of trees may increase the rate of growth by stimulating more or less constant growth during the season. In a Department of Agriculture experiment, the GA was applied as a 1% paste in a band around the terminal bud of trees. Treatment was repeated three times during the summer. Walnut tee growth was 8.5 ft. for treated trees, 1.5 ft. for untreated trees.
6. Frost protection. Spraying fruit trees at full-blossom or when the blossoms begin to wither can offset the detrimental effects of frost.
7. Root formation. GA inhibits the formation of roots in cuttings.

Recipes

Although GA is not listed as a "poison", the following precautions should be observed: Flush with water any GA that may get into the eye. Avoid skin contact if possible. If skin contact is suspected, wash with soap and water. Do not re-enter an area after spraying until the GA spray is fully dry. Avoid ingestion of GA. The powder may be dissolved as specified below to give the desired concentration.

female flowers by concentrations of 200 to 300 ppm

so to get your female seeds you need to first start with a female and spray her branches to induce the formation of male flowers on her to polinate eithet itself or another female. the seeds produced should then be all female...

but its good to know GA also helps germination for those hard to germ and older seeds....

__________________

I'm assuming that the GA will also push a seed to female considering the many things that can be done to promote females already by gentle growing practices and nutrients

i shouldnt think so.. all the literature i've looked up is specific about the formation of fem seeds. its the application to the growing tips at flowering that makes males for the pollination and then the seeds are fem seeds.

i guess its all about when you use the stuff. it promotes different reactions at different stages of growth... aparently its a growth hormone
