POLYPLOIDS

Saw an interesting article on hightimes, thought I would share....gonna mess with this, let you know how it goes....my goal is to produce and breed a male & a female of the same strain...1998-12-28

Q: I can't seem to find much information on polypoids, it seems to be a lost art these days. Any chance you could post some info on your site? I'm interested in trying it out, but I can't find any resources! Can you help?

-- Seeker of the Polypoid

A: A polyploid is a plant with twice the normal amount of chromosomes in its cells. Cells reproduce by replicating their chromosomes and splitting. As the cell divides, the new chromosomes become the nucleus of the new cell. In a polyploid, the replicated chromosomes do not seperate. They remain in the cell causing it to have twice as many as it should. Although polyploids are no more potent than their normal counterparts, they have been found to be larger. The most common way to force a plant to become a polyploid is to soak the seeds in colchicine. Colchicine can be derived from the bulbs of the crocus plant. Mash the bulbs and add equal parts of the paste and water. Strain the mixture and soak the seeds in it until they sprout. Plant and care for it as usual. Only a small percentage of the sprouted seeds will be polyploids. They will generally have thicker stems, and may have unusually shaped leaves.IMPORTANT NOTE: Colchicine is poisonous and should only be used on seeds. Never treat a living plant with it, and use extra caution when handling.

sounds whack.

but bigger is better if the potency isnt changed.

i will investigate information about polypoids for you.

Colchicine is a highly poisonous alkaloid, originally extracted from plants of the genus Colchicum (autumn crocus, meadow saffron)

Though some true crocus bloom with the fall rains, after summer's heat and drought, Autumn Crocus is a common name used for Colchicum, which is in the lily family (Liliaceae), and which has six stamens.


Cant find info easily on polypoids affecting growth, just a few vague references to plants being bigger..

sounds intriguing

Here are the only other articles on polyploids I have so far....sounds very interesting... 420 yall!

Building A Better Polyploid
1999-06-01 >> Q&A DB Home

Q: High Guys,I do work in agricultural genetic research and I'm just wondering if you have made any attempt at artificial polyploids? We used extremely dangerous chemicals for this so I could not obtain some for home trials. If so have the outcomes been as successful as some of the common polyploids (banana, cotton and many other economically important plants), how about all polyploids by breeding with closely related species for a more vigorous hybrid (mule). Thanks for the info.

A: Dear Speed,I think your knowledge on polyploidism is far greater than mine. Maybe we will find each other on the new 420.com chatroom and I could pick your brain on the subject. Your most likely to find me between 8-10 PM.I have come across a few dozen polyploids over years of growing, around 75% of them were female. I never had the chance to do the one thing I always thought would produce a high likeliness of polyploids. Pollinate a polyploid female with pollen from a polyploid male! If you are proficient at collecting and storing fresh pollen, you could introduce that pollen a second time. Grow out the first batch of seed, hopefully they will be polyploid. But I am guessing that you won't even get 50% at this point. But if you pick a poly girl and knock her up with the poly pollen one more time, who knows what could happen!

Polyploidy Phenomenon
1998-04-11 >> Q&A DB Home

Q: I have recently seen a plant with three branches from each node. The plant started with a set of three leaves instead of the normal two, and continued to grow sets of three. The plant appears male, but it has not been sexed yet. Have you heard of such a plant? Do you think it will produce more buds?

-- K-Dog

A: Yo Dog...the phenomenon you are encountering is polyploidy. Sometimes extra chromosomes develop in each cell and cause that third set of leaves to appear. And that will lead to, you guessed it, three bud sites at each node! (IF it turns out to be a female of course.) I have harvested several polyploid females, and they do tend to yield 1/3 more than a typical diploid female. I have also seen some of these plants turn out to be male. Much to my disappointment looking back, I never got around to doing any breeding with polyploids. You should know that it is a rare occurence, but I can't help but wonder if the frequency could be increased by breeding a polyploidal male and female?

heres another valid link to a university study

Poly s rock.....since my last post a year and change ago I have found that polyploids are far superior tonormal mother plants....more to come....

polyploids have been discussed for at least 30 years, and the general concensus is 'extremly varied results' ... you are highly likely to destroy lots of plants to come up with a 'winner', that typically shows little or no improvement over a standard plant ... it sounds exotic, and mysterious, so it's 'legend' has hung around for years, but its performance just doesn't make the grade .. if you want more buds, grow an extra plant ... :D ... but, some growers like to experiment, so go for it ... :smokin:

this should really be in the "Advanced Growing" section, so newbies dont get all excited and get hurt, colcichine is dangerous stuff

lol :)

polys are worth looking into....all you need is some seeds and a crocus plant.....check out the links to high times articles, as well as agricultural studies by colleges researching the use of polyploids to increase the nations food supplies....
