Plant hormones

[loupgarou]

Just a conversation with dr mallick
---

Cryptocoryne parva is not a moss. Belonging to the Araceae family, it is a
flowering plant - the smallest known species originating from Sri Lanka. It
is a slow growing plant requiring plenty of light and takes 5-6 months to
give a turf like appearance.

It grows well in pH range of 5.5 - 6.8 and in a temp range of 22-28 degree
Celsius. This species is prone to the infamous "Cryptocoryne Rot" whereby
the leaves disintegrate due to transplant shock, changes in the water
chemistry, light intensity, etc.

I have not done any research on this topic. However, you can give it a try.
Grow the plant in a separate culture tank with no fish. Add the rooting
hormone @ ONE gram per litre of water. Supply plenty of oxygen using an
aerator. Adjust the pH to 5.5 - 6.5. Wait and see the result. Be patient -
it might take 2-3 months to see any visible result.

The rooting hormone is very cheap. you can pick it up from our retail
outlet at Block 462 #01-K1, Ctawford Lane, S - 190 462. Please call Mr.
Fong at 6294-6578 before you go.

Have any1 tried using these plant hormones from Dr. Mallick in your tank?

[loupgarou]

no control tank to verify any changes/speed of growth etc.

[GaspingGurami]

Any observations Chris?

Did the C. parva pick up speed?

[seed75]

Dennerle PFLANZENGOLD 7 is supposed to be some form of plant hormone
>> >mix.

does this line means that Denerle GOLD 7 itself have some form of plant hormone mix in it, what helps the plant along the process. Better bloom or stability in keeping the plant alive?

Read it this way..

Dennerle PFLANZENGOLD 7 is supposed to be some form of plant hormone mix.

Hope it's clearer now.

i didnt quite understnad the IAA indole-3-acetic acid part.
Is it part of a chemical inside Auxin?

[ranmasatome]

It is a certain type of auxin..

[Plantbrain]

I've never found that any submersed oplant grew any better with hormones, nor has anyone shown that it does to date.

The only references is that it induced some flowering in some Crypt species that where grown in emergent culture for an only one time effect.

I did that same experiment with the same species, it worked.
But no other parts of the plants grew any different.

Basically, don't waste your $ or time no believe in all that baloney.
Doesn't hurt, but does not help either.

Hi Tom,

so its not really necessary to use hormones on plants?
only use them if you really want them to bloom? correct me if im wrong
But does it someway or another harm the plants if we use hormones often?

Thanks

[Plantbrain]

Adding them does no harm, but it also does no good.

If you are an emergent Crypt grower? Perhaps.

Otherwise, no.

Spraying concentrated horomones on a terrestrial plant is very different and is done for larger flowers, bigger fruit etc.

Or inhibition with herbicides that target hormone production biosysnthesis. Plants do what they need to do just fine with the basi c building blocks, I'd suggest you stick with those with aquatic plants.

Dr Kane does tissue culture at UF in florida and is a good friend of mine.
We have had several discussions on hormones which is a good deal of his focus in TC methods and he deals with aquatic ornamentals.

You can also see the effect, or lack of effect, by doing it yourself, and spend some $$, you'd learn more by doing basic maintainence and reading my site.

A few $ is what they want you to spend for the hormones. Not so much because they really work in submersed aquatic plants, but because they want your $ and it does not hurt the tank(nor help).

There is a little basis for it in terrestrial plants in grape production and with agricultural crops etc, but vegetative aquatic weeds have little need for such manipulations.

wonderful... one less thing to get 'addicted'...

[Betta Almighty]

Thanks Tom. Will check your site out.

[Plantbrain]

I'll be doing an intensive literature review article on hormones in aquatic plants some time this or next year on the BarrReport.

This month is Iron and Mangaese, about 20 pages worth of stuff few have ever read or heard, same with every article I write.

It's heavy reading, not light simple stuff, the web already has lots of those types of article, no sense in repeating that.

The site is much more a magazine style web site, and not so much a forum, but there is a public side to the forum etc, aqua bid some plants to pay for the cost , I'm up front about it(no premimum memberships, request for supporting members, no advertiments banners and vendor forums etc, the hobbyists are my vendors) and support the hobby. So does AQ forums and other forums. I'd actually prefer folks use plant dollars, most end up saving much much more on the site than they ever spent. Help those that help you.

Hi Tom,

Thanks for sharing it with us. Appreciate it.

[Plantbrain]

I have not written it yet with hormones though But what I do know with respect to aquatic plants is that it does not do a whole lot.

I've done some back ground checking, but not the intensive type.
