Effect of Magnetic Field on Germination and Plant Growth

found a sweet research article at:
Acta Horticulturae

This paper describes the effect of alternating magnetic fields on plant germination and growth. Experiments were conducted utilizing various frequencies and two states of polarity. Electromagnetic coils were used to generate the fields and 'Komatsuna' plants were chosen as subjects. The frequency was varied from 1 to 1000 Hz, at a fixed intensity of 4 or 5 Gauss. The magnetic polarity was controlled by reversing the current direction. Measured parameters were germination rate, growth rate and yield of the plant. The results indicated that magnetic fields do influence plant growth and germination :mrgreen:, and that frequency of the field is a more important factor in germination rates than polarity. Maximum germination rates, which were 20 % higher than control rates, were obtained at around 10 Hz :joint::joint:. An alternating magnetic field of 10 Hz was shown to have a statistically significant effect on plant growth, as measured by leaf area. The difference in growth rate between treated and control plants decreased after the field was removed.

Did some more googling...
So, hook up a function generator kit:
Gibson Tech Ed - G-159P Function Generator Kit

to an electro magnet.. at 0,10 hz. ==> FASTER, MORE GANJA

Is this a joke? How do you hook up an electromagnet to the function gen??

Anyone want to test this out, or buy the article and tell us what settings to use ;-) ?

I'm finding a lot of recent evidence... So for VEGetative stage, USE A MAGNET (south end of the magnet)

check this out:
CORDIS : News

"
Cryptochromes are photoreceptors which are sensitive to blue light, and they are involved in a number of processes linked to the circadian cycle, such as growth and development.

To determine whether the magnetic field influences the function of the cryptochromes, researchers from France's National Centre for Scientific Research (CNRS) and universities in Frankfurt and Marbourg grew the plants in the presence of blue and red light and magnetic fields of varying strengths. They found that increasing the magnetic field only increases the inhibition of the growth of the hypocotyle in the presence of blue light. When red light is used, the plant uses other photoreceptors called phytochromes, and the growth of the hypocotyle (stem) is not affected by changes in the magnetic field. Furthermore, mutant plants which have no cryptochromes are also insensitive to changes in the magnetic field.

The study shows for the first time that in plants, the work of the cryptochromes is affected by magnetic fields and suggests that the mechanisms of magnetic field perception in plants, and by extension in migratory birds, use the same photosensitive molecules. The researchers also suggest that, as cryptochromes have been strongly conserved throughout evolution, all biological organisms could have the ability to detect magnetic fields, even if they do not use them.

I am not a physicist, but it sounds like you need to create an electro-magnetic field - just sticking some magnets in your grow room wouldn't be the same. A magnet produces a magnetic field but an electromagnetic field requires both a magnetic AND an electric field. also - the article specifically states polarity is irrelevant so it doesn't matter which "end" of the magnet to "use".

I found a few experiments that used normal magnets-- the south end makes it grow more... north will stunt growth...

The electromagnetic experiment was WAY out there... I've read that using a magnet with gauss rating of only 6 will produce results... so any magnet really should give results... but... I figure on trying it with some bag seeds at least to see for myself...

Aw great now I need to spend more making an electric field.... But seriously at my place I've got a plant that climbs all over my ceiling & walls it's about 30+ ft. long, but where it passes near the panel or any plug outlets, switches, all the leaves fell off... Looks odd... 15ft. leaves..... then crop failure, not a leaf for 10ft. Then 10 ft. with leaves....
You try it, I hope it works...let us know

Check this out.. NASA did a experiment like this in May/2002: Sowing Seeds in a Magnetic Field

Ahhh I found a good forum full of info..
GM seeds vs. Magnetic GM seeds - The Environment Site Forums

"He then began experimenting on plants, and he found that when seeds were placed directly on a magnet (1500-2500 gauss strength) for several days, then planted, they had improved growth characteristics. In most cases South pole exposed seeds grew into stronger, more vigorous plants with better yields. North pole exposed seeds grew into smaller, weaker plants with lower yields. This was not always true, however. Depending on the species, some seeds responded best to the North pole, and sometimes both North and South pole exposed seeds were an improvement over unexposed seeds."

Oh no - a politically motivated site! When they mix politics with science, the science becomes less trustworthy. Bummer.

My old man worked for monsanto for 37yrs.. Without GM we'd all be growing bagseed......
Butttt ! my tomato would taste better

that is awesome! Your Dad worked for Monsanto? Is he the evil, corporate, money-grubbing, enslaving, people-hating demon-spawn the eco-terrorists paint Monsanto workers as? Or is he a caring guy that wants to end world hunger and make sure everyone is fed?
