RE: Electro-culture: Stimulating plant growth with electricity (research thread)
The effects of electricity on plant cell metabolism processes can also contribute to plant growth and development depending on how its administered, according to a 1985 New York Times article on electricity and plant growth. Research conducted in 1985 by the Imperial College in London examined the effects of electrical current on tobacco plant cells grown in a laboratory setting. Results from the study showed growth rates increased or decreased depending on the direction of the electrical current, meaning negative currents promoted growth rates while positive currents had an inhibitory effect. The results of the experiment occurred gradually with noticeable changes apparent after 10 days and dramatic changes taking shape after 22 days.

Grow healthier crops: the art & science of electroculture.
Publication: Countryside & Small Stock Journal

Full Article Title: Grow healthier crops: the art & science of electroculture.(The garden)

Article Excerpt
Electroculture is the use of sound and natural electromagnetic energy to stimulate plant growth. It has been practiced in various forms for over 250 years, but research into it has decreased in recent decades. Nevertheless, there is still much room for research on these methods, and many discoveries already known. The following is a list of some known electrocultural methods which can be employed to enhance plant health, crop yield and quality, or cold-hardiness, as the case may be for each particular technique.

* Low-growing vegetable crops can be stimulated to more vigorous growth by placing a row of open metal cylinders parallel to each row of the crop. Ordinary aluminum cans or tins may be used (but not steel cans). The tops and bottoms should be removed from the tins, and each resulting "tunnel" placed upright next to a seedling, until each growing plant is adjacent to a small cylinder. Each cylinder should be pushed firmly into the earth, so that the lowest 3cm of it are below ground level. The metal will conduct the earth's electrical charge upward, stimulating cellular activity and nutrient uptake in the plants.

Struggling to Take Root: The Work of the Electro-Culture Committee of the Ministry of Agriculture and Fisheries Between 1918 and 1936 and its Fight for Acceptance

by David Kinahan, Department of Science and Technology Studies, University College London


ABSTRACT

Since the eighteenth century, many scientists and entrepreneurs have explored the idea of using electricity to make plants grow faster. In 1918, the Ministry of Agriculture and Fisheries were so enticed by the idea that they set up a committee to investigate. Here, the work of this committee is discussed using the eighteen Interim Reports that they published between 1918 and 1936, the year that they were disbanded. Furthermore, reasons why the committee was axed, despite some considerable successes, are considered. It is concluded that the Electro-Culture effect is a real one, and that the Committee was axed as a result of economic pressures, not because the idea was wrong.

RE: Electro-culture: Stimulating plant growth with electricity (research thread)
Besides perking up light-starved houseplants, what practical applications might a photovoltaic electric root stimulator have? Well, for one, tests have shown that seeds placed within an electric field sprout more quickly and are more prolific. So if you used a solar disk on your starts, instead of having—say—only 50% of your seeds germinate, you could expect a success rate of 75% or better.

Second, root stimulation works particularly well on seedlings, so a solar cell could be able to help you germinate and raise your starts indoors before the spring thaw comes. When it finally warms up enough to put your young plants out, you'll have a good jump on a healthy garden, one that has hearty, substantial stock rather than fragile, underdeveloped seedlings.

RE: Electro-culture: Stimulating plant growth with electricity (research thread)
The report I ran across discussed the effects of bathing radishes in ultrasound. One flat of seeds was placed in an environmentally controlled chamber with 50,000 CPS ultrasound piped in at an output of about one watt; the second group (called a control) was set in an identical chamber but did not receive exposure to ultrasound. Artificial lighting was switched on in both chambers for 12 hours each day (during which time the experimental flat received ultrasound). Both groups were watered and cared for equally.

After about seven days, the seeds in both trays began to sprout. One week is just about the normal germination period for radishes, so up to that point in the experiment, ultrasound didn't seem to offer any benefit.

It soon became apparent, though, that the seedlings receiving ultrasound treatment were growing much more rapidly than their control counterparts. In fact, by the fourteenth day the experimental plants were half again as tall as the ones in the "quiet" chamber.

The experiment continued for 28 days, the same period of time used in the photovoltaic root stimulation tests. By the end of the test, the plants treated with ultrasonic vibrations had grown an average of 87% taller than their control cousins. (The actual growth rates are shown in graphic form in Fig. 2.) Repetitions of the experiment were run to confirm the initial results, and some of the later tests showed growth rate increases of as much as 150%!

I've just read somewhere that some guy claimed that actual electrodes spiralling along the plant's main stem was the trick.

RE: Electro-culture: Stimulating plant growth with electricity (research thread)
This is one of the things that I'm trying to specify, mate. It seems that when the electrical current used to stimulate the plants is pretty low, like a PV cell, then if the plants get all the sunlight they need, you're not gonna see a big difference. Or so the experimental data i've found said, at least.

On other cases though, where the current is stronger than that of a single PV cell, like cables burried under a field, or like the case of a badass farmer who buried a huge copper plate on the one side of the field, and a huge zinc plate on the other, and connected them aboveground, thus creating an underground electrical field, a huge improvement has been observed on the plants. Now here is the catch:


On the experiment done with PV cells on plants growing with plenty of sunlight, the average height and plant mass was calculated. Seing no big difference, the results were categorized as unsuccessfull.

What they didn't measure though, was the quality of the end product. On the case of the farmers playing with electricity, it is mentioned that the end product, the fruits and vegetables, of the stimulated plants, were far superior to the ones that were not. Shelve life was multiplied, and overall quality was way better.

On the PV cells experiments though, no measurement or observation upon the end product is mentioned. I don't know if this was due to the fact that it wasn't worth it, or due to negligence. We'll have to find that out from our own experience.

Abstract

Goldsworthy, A. and Rathore, K. S. 1985. The electrical control of growth in plant tissue cultures: The polar transport of auxin.—J. exp. Bot. 36: 1134–1141.

The reasons for a many-fold stimulation of shoot formation and a 60–70% stimulation of growth in tobacco callus caused by passing a very weak electric current (1 or 2 μA) between the callus and the culture medium have been investigated. The stimulation of callus growth occurred only when the callus was made negative to the medium and then only when IAA was added. It was abolished, even in the presence of IAA, by the addition of TIBA which is an inhibitor of polar auxin transport, and also when the IAA was substituted by either IAN or the synthetic auxin 2,4-D, neither of which show significant polar transport.

This suggests that the electrical treatment may have aligned the physiological polarities of the callus cells so as to promote the polar transport of IAA into the tissue when the callus was negative to the medium.

If so, the enhanced shoot formation may have been due to the parallel orientation of the growth axes of individual cells so as to make the production of organforming meristems more likely. The mechanism of the effect and its relationship to the natural forces controlling differentiation is discussed.

Abstract

Results are presented that show a promotory carry-over effect, of an electroporation treatment of isolated cell suspension protoplasts of Colt cherry (Prunus avium × pseudocerasus), on the growth of protoplast-derived calli and on plant regeneration capacity. Callus from protoplasts subjected to three successive exponential pulses at 250 V or 500 V showed the largest fresh weight increases between subcultures, and also exhibited the highest frequency of plant regeneration based on the number of shoots per callus. These shoots, in turn, produced a more prolific root system when compared to those derived from non-electropulsed protoplasts.
