Tetraploid and triploid seeds

[mudballs]

No..
A pollen grain on the stigma grows a tiny tube, all the way down the style to the ovary. This pollen tube carries a male gamete to meet a female gamete in an ovule.
The grain has a 1um cavity containing the tube...and can vary in size significantly
I'm saying when they meet and try to make a zygote...shit goes wrong

I've had my say, I'm out.

Ur one of the few i like talking to about stuff!...@mithridate around? ...guess not

You make contact more than misses when you swing

Djonkoman isn't around anymore either.
I've given this my best guess, I can't argue about this, as it's just guesswork. I can't say more than I have already.

Ur probably right about the haploid diploid stuff...im thinking ur idea of deliverying the genetic material is maybe not worded in a way i expect to hear it

How did you identify that the male was a triploid?

I'm not 100% it's a triploid.. ive always called a plant with an extra leaf and flower site a triploid.. I'm not to informed on the scientific stuff about them... i know the basic information...

Yeah tetraploid diploid is talking about the amount of chromosomes. They are created with a chemical called colchicine.

Three or more shoots from the same node is called a whorl.

Update?
So triploid x triploid would produce no viable seeds or 98 less%? Explain it like I'm a child
Thanks

"When triploid plants try to reproduce with other triploid plants, their offspring will end up with an odd number of chromosomes (3n + 3n = 6n), which is usually not viable for the plant to survive. This results in no viable seeds being produced. Additionally, triploid plants often have difficulties in meiosis, the process of cell division required for sexual reproduction, which further hinders seed production"

In theory, a triploid male would produce two types of pollen a) diploid (two DNA samples) and b) haploid (one DNA sample (the normal way)).
A female triploid would do the same with their pollen receptor sites (ovums).
The diploid pollen maybe too large for the female haploid sites, but would pollinate the diploid receptor sites. The haploid pollen would pollinate the haploid receptor sites, and would produce normal diploid seeds. The haploid pollen may, but probably not in most cases, pollinate a few diploid receptor sites, creating more triploid seeds, but greatly reduced in number. The diploid pollen may pollinate the diploid receptors, if the haploid pollen didn't get there first, and create tetraploid seeds.
So in the reduced seed sets, I would hazard a guess, that you would end up with a mix of normal seeds, triploids, and tetraploids.
But that's all guess work and should not be considered gospel.
Wish djonkoman was still around.
Only way to know is to do it. Then test any seeds produced. But people in that position are more likely to produce papers and patent applications that post their results here.

I'll never spend money on this sterile bullshit.

Hey, want germplasm you can't reproduce?
(...)
People don't want to admit that the profit motive makes shit worse for everyone.

With all due respect to the OG growers, it seems like a speech that could have made sense in the 80s, not in 2024: the profit you're talking about in the canna-business ($) today comes mainly from the sale of elite clones flowers and from the sale of autoflowering seeds, two forms of business independent of the fertility of the strains.

In this scenario, it seems to me that being scandalized by some sterile seeds is a bit anachronistic.
