hi, my name Alexander Riyanto from Indonesia, i am 36 years and arts in plant.
i read many forum that many dissuc talk about forced or creat variegate instant by chemical, is real possible or just junk notification? can some one explain to me. and if any chemical product, what that the name?
because, in plant variegated, have reason for:
1. inchlorophyl by some colchicine or combine aucxin, cithocinine and gibberelin
2. create high xantophyll pigmen with uv lamps or used chemical
3. cross with variegated plant.
thanks if any information for that.

Alexander!

Presumably you have to cause a genetic change in a normal plant to induce variegation. You can probably breed some kinds. Otherwise the chemical agents which would mutate the DNA would be quite hazardous to handle and a bad idea to use at home. Other than the safety issue, which is huge, they are not likely to cause the desired change except at a vanishingly low frequency... most mutants will be in other parts of the genome (including "junk" DNA which does not necessarily cause any visible effect; or DNA that's required for life, and the loss of function there results in a loss of life).

Some chromosomal changes have been forced in the plant world by introduction of mutagens: chemicals, irradiation or by introducing viruses. It is dangerous and, although once widespread, is not an accepted practice anymore.

The old fashioned way (selective breeding) is the best way to affect a change in any plant (or animal)

Sometimes accidental over-spray of round-up causes a variegated look to foliage. It is undesirable and not permanent.

Roundup works by disrupting the plant's ability to make amino acids. It doesn't change the genetic makeup of the plant.

It seems like a viral type of variegation would be the easiest to pursue/induce.

I think the large bulk of variegation occurring in plants is of the chimeral type.

I'm suspecting that if producing variegated forms of plants (I'd be most familiar with garden perennials) was currently feasible, modern plant breeders would be producing more variegated forms of common garden plants.

There's also the point (for perennial gardeners) that variegation typically weakens perennials. Virally induced variegation may be especially harmful to plants, eventually proving fatal.

The variegated forms of some very popular house and landscape plants are the result of viral variegation. It is not the most common form of variegation, but there are existing applications of manipulation.
