Silly genetics question. Maybe.

[Blippy The Slug]

Since I noticed the triploid branch on the Wheelchair Project, I've had this silly idea percolating through my head of getting hold of some pollen and fertilizing at least 1 node of that branch, should it turn out to be female. My (fuzzy) logic being that a triploid plant would have half again as many nodes, or 1.5 times the yield of a "regular" plant.

EDIT: In checking the plant over carefully, I noticed all the branches (except the "triploid") are 1st node 2 leaf, 2nd node 1 leaf, 3rd node 2 leaf, 4th node 1 leaf, etc. Every other node is a one leaf node. This makes me even more confused. As though this "even odd" is either triploid phenom "elongated", or the "triploid" branch is "even odd" squatted down. (What is the correct term for this type of "even odd" growth?)

So...

Are tri-lateral nodes/even-odd nodes a genetic thing? Or is it caused by stress of some sort? I'm confused because only one branch is displaying it. Other branches are displayed the "even odd" thing.

If it is a genetic thing, is there some reason this type of trait shouldn't be bred in?

Did I get seeds from a mad breeder trying to make a triploid indica?

Huh? No... I mean one branch is triploid, and all the rest of the branches on that plant have even-odd leaves on the nodes: 2-1-2-1-etc. I'll get better pics of the even-odd thing tomorrow - I have the digicam till after new years - but I thought the triploid pics were pretty clear.

And I want to get some pollen to fertilize a node if it's girl, to see if this triploid trait can be passed on.

Or mebbe I should just clone that branch? Hmmm...

I missed that link~
Wait a sec...........

[Pharm Girl]

I'll check the show in 2 hrs and see about that~
I'm certain my M's do that, they are a branchy, leafy and fragrant~
The troops are on their way..........they are on THC break~

I think kosh is the one you're after, he's the triploid authority.
My thoughts would be, it is a genetic trait....perhaps realised potential due to stress....or health in that one branch. But I havent seen that when plant is stressed, always genetic.
I go with the breed recessive genetics theory, so I'd take a cutting off that branch.

As promised, here are pics of the "even-odd" thing that's happening on all the branches except the "triploid" branch. At first glance, some tips look kinda like they're going triple, but if you look close, you can see that it's the "even odd" thing.


PS - I'm trying a new image hosting service w/clickable thumbnails. Lemme know how it works for you.

From and older post if its of any use:>

The mutant plant you are refering to may be like my avatar, known as 'tri-ploidy'....where as the normal seedlings are di-ploidy. So the mutant bassically has an extra set of chromosomes.

A while back I had the same idea, that I would get the tri-ploidy(happened to be female) and cross it with a normal plant and hopefully get at least some tri-ploidly offspring. I did cross that tri-ploidy female with a normal male plant, harvested the seeds, and then proceeded to test a great many of the seeds. All the seeds produced normal di-ploidy seedlings. In other words the plan was not fruitful.

Having failed, I then did some research into the subject and found out that if you cross a tri-ploidy and a di-ploidy you will end up with di-ploidy(normal) seedlings. Also, if you happened to have a female tri-ploidy and a male tri-ploidy and crossed them together, the offspring would revert to di-ploidy.

There is an elabourate scientific explanation for that, but I will leave it up to you to dig up what you can. If you search google for 'polyploidy' you'll find what your looking for.

I'd mention though, that there are ocassions where tri-ploidy is produced in the lab for agriculture, water melons for example so they are all seedless. Aparently the tri-ploidies are sterile so won't even produce seeds if pollinated by themselves...or something to that effect.

How they go about producing the 100% triploidy seeds/seedlings/plants...is to artificially, with hormones, create mutations on plants, and for lack of a better word, make a 'quadploidy' which is a plant with four leaf sets, or two sets of chromosomes. So when you them cross a 'quadploidy'...which has four chromosomes, with a normal 'di-ploidy'....half of the chromosomes from the 'quadploidy' are passed on...which is two...and half the chromosomes of the -di-ploidy are passed on to the offspring....equalin g 3.


Today----As it happens I have another triploidy right now which is doing quite well and is a female.

Any way...what you are refering to is when the triploidy manifests itself on one branch rather than being born that way as a seedling. On another plant I have, also on one branch I have noticed a mutation which seems to pop up now and then. While it is not triploidy as such, the branch is flat instead of round and has an abnormal amount of nodes.

What I think can happen, is that within a particular strain of the good herb...all strains are in fact present in its DNA but it just exhibits the charcateristics of that one strain because certain genes are switched either on or off. Sometimes, for some reason or other, stress or just genetics, the plants can suddenly, 'perhaps', switch on a particular gene, perhaps only in one branch and start to grow abnormally compared to the rest of the plant. These mutations on fruit tree's for example are know as 'sports' and sometimes because they are thought of as unique or special, the sports are propogated and then interbred to create new varieties.

The question is, if one were to pollinate that one branch, would its genetic material differ from the genetic material which is present in the rest of the plant...if indeed it is a genetic trait as opposed to merely a chemically induced mutation...such as when one radiates plants, or adds hormones which also make them do funny things. Still...its worthwhile to experiment and record your findings cause you never know when you will make the next big break through with the coochie pine and help lubricate its passage through time.

Off topic...I am still wondering if a certain technique I happened upon by mistake will create 100% females from any seeds.

As do I. That was one of the most information packed responses I've read, and set me off on another flight of research. (gives kosh a reacharound) Thanks, bubu!

It's good research material, get those clones and start learning.
Your skills will be rewarded.
