Thanks for the support. I’ve been working on creating a hyperblooming mammoth variety. The trick is creating the cross without triploidy. I’ll be selling the seeds in a few months if you’re interested.

Thanks Michael. Interesting! You’ve given me ideas. I have all kinds of tomatoes especially come up from my composting.

How did you avoid self-fertilization? As you rubbed the pollen on the flower, won't its own pollen get into the mix and stick to the stigma?

Sorry just saw your question. I think I answered it above. It’s not perfectly scientific but let me know if you have any questions.

Rookie question! Last year I grew a sunflower from seed that I had saved from the previous year. The first blooms were stunning. So, I covered the following blooms before they were mature with an organza bag. I shook the bag every so often thinking that the bloom would pollinate itself. I harvested the seeds when the bloom was dry. I planted the seeds in the greenhouse six weeks ago and none of them germinated. What did I do wrong? Thanks for your time!

@thechaosgardener 3 ай бұрын

They might have not been fertile seed. Some hybrids don’t produce fertile offspring. One thing that might have gone wrong is in pollination, you need an even number of chromosomes. Depending on the genetics of the parent some hybrids end up with an odd number of copies of chromosomes (google polyploidy and triploidy if you’re curious). I’m not saying this is what happened but I did some crosses that resulted in nonviable seeds and I think that’s what went wrong. Polyploidy or duplicate chromosomes is how we get giant fruit including corn and wheat and even strawberries which used to be small. Interestingly strawberries are octoploids which means they have 8 sets of chromosomes. Seedless bananas and watermelon have an odd number of chromosomes. Let me know if that helps.

Thanks so much for your helpful response! Interesting that we were just talking about planting a field of strawberries! I’m going to give these fellows another shot in the greenhouse and see what happens. If not… I will assume that they are not genetically complete and unable to bear. Hope you are well and have a wonderful day.

Thanks for the video. I appreciate the info. If I want a complete cross-pollination without pollinating the same variety to avoid getting no visual changes, I should only use the paper towel once per flower I'm pollinating? Correct? Once a flower is pollinated by the paper towel, the paper towel picked up pollen from that flower ultimately collecting both pollens? So collect pollen from my flower of choice and only transfer it once then discard the paper towel? Does the pollen affect all the seeds if it reaches just one stigmas or do each seeds contain their own individual stigma? Are each seeds technically a different flower/stigma?

@thechaosgardener 2 жыл бұрын

The objective is to gather a significant amount of pollen from one flower and attempt to transfer that pollen to the stigma of another flower before it’s pollinated by its own anthers. I speculate that there is a lag period of when flowers are receptive to pollen before they produce viable pollen on the same flower. Also within a single flower it’s possible to have receptive stigma before there are mature anthers. If you look closely at the flowers you’ll see what I’m talking about. The tiny flower stigma change color as they become receptive and also the anthers change color when they are producing “ripe” anthers/pollen. Either way it’s fun to see the results of future generations. I try to write down the parentage so I can keep track so I can try to predict phenotypes

@@thechaosgardener That is “normal” cycle of things. But....in the 5-7 years we’ve seen some very brief but cold dips. Last February it dipped to 16!! And stayed in the mid to low 20’s for almost a week. I thought for a moment I was still living in Idaho!! Lol. My lemon & fig trees paid for that dearly. Some broccoli & mustards survived but the onions, cauliflower and cabbage “yielded up the ghost”. Also the garlic took it in stride and came through nicely.

@bagelbananaalt5536 Жыл бұрын

I always get nervous when touching the disc florets because I'm worried I'll break them especially when rubbing the inside of the flower because I grow dwarf sunflowers varieties, and also when it does self pollinate, is that bad?

@thechaosgardener Жыл бұрын

There’s a high possibility of self pollination that’s why you have to grow the offspring to see if you got a hybrid that you like

@@thechaosgardener I went out last night to pollinate them the first ones bloomed 4 days ago and they are already pollinated. I had to laugh I had no idea bees liked them so much. But I am going to cross pollinate my mammoths with the wild sunflowers in the feild behind me that haven't bloomed yet. I am so excited. Thank you for this video it literally explains everything I needed to know.
