Just make sure that the stigma and style do not break.
"Just make sure that the stigma and style do not break."
From Keith's website Crossing Tomatoes page. Let's say I snap the stigma off. Couldn't you still put pollen on the ovary? jt |

Thanks Keith!
There are a lot of hybridizing questions on the hot pepper forums that I frequent and I always send them to your most excellent site for information. Capsicum flowers can be awfully small to work with. BTW, looks like something green is growing on you lens. jt |

Hey PPPP and even more Ps,
Been a long time! And I had a reply from Jeffner too this week. Also had email from list mom Janice. A great week with old friends! If you ever stop over in California again let me know in advance and I will try to be there. We sure had a nice visit! Not sure if this will work... Depending on browser it may prompt you to dl plugins. Dial up connections might take a long time. http://www.fototime.com/9D176ACD105A434/conv.wmv Poor quality and will bring palmcorder next time. Hot regards! jt |

PP, remember our date for 2008?? Maybe we need to talk itinerary soon.
Funny, I was thinking about Janice and especially Gordo just lately. Got a much unexpected email from Allen just before Christmas. jt, does he have an answer to your question here? Hugs, Jeffner, off to the Omaga 3 trials and cardiac rehab (will respond email later in the day, PP with the fancy decorated legs) |

Allen says as far as he knows it's no stigma no pollination. But that he would "ask around". I think he's actually met Dr Bosland.
You tomato people are probably wondering who the heck is Bosland? He is THE MAN to us pod-heads. Unbelievable how many rare accessions I've grown from the USDA & German seedbanks were collected from various countries and cataloged by him. Kinda a chile-head version Dr CMale except more mobile. |

Hey JohnT:
I thought I would pass your question to Dr. Congo Joe. Here is his reply.... Question: If the stigma is clipped off before receiving pollen can the ovary still be pollinated? +++++++++++++ Not likely. The pollen is thought to need a special environment in order for the pollen tube to germinate. Thus, removal of the stigma surface prevents pollen from correctly growing. After the pollen lands it grows a tube (the tube looks like a root but is not a root). The tube grows down into the style and carries the sperm nucleus to the ovary. The sperm nucleus must move down through the pollen tube in order to be united with an ovule; only when the sperm nucleus enters the ovary cell is it considered that pollination occurs. So, pollination (in the sense of fertilization) actually requires that the pollen have a correct environment for germination, then successful pollen tube elongation must occur, and finally the sperm nucleus must be delivered through the tube to unite with the ovary. There can be many hours between when the pollen lands, and when the sperm nucleus unites with the ovule. Removing the stigma would mean that pollen would land on a cut surface, and it is thought the proper pollen tube germination does not happen in such a case. Note from the troll..... I'm growing a cactus plant that Joe collected on one of his field trips. Called a "horse crippler" wicked spines Joe was a PhD of Botany at Auburn, plant pathogens his specialty. He now works in the private sector with the human genome. More to follow. (I knew my friends would come through!!!) |

I have a pretty good .pdf file for more info, but don't think I'm allowed to attach anything like that here. And I don't have a website at the moment.
If anyone wants, just email me. |
