发帖数: 16778 | 1 I googled the structure of a watermelon flower.
Some websites show there are stigma and stamen in the same watermelon flower.
For example,
I am not sure if it is correct.
Please let me know what is the stigma part, and what is the stamen part,
if the female watermelon flower contains both.
thanks. |

发帖数: 16778 | 2 This is first time I found a watermelon flower with stamen and stigma both.
Is it strange?
Before all I found are male flowers with stamen and female flowers with
stigma.
questions:
1) do I still need to pollinate the flower which contains stamen and stigma?
2) should I use the stamen in the flower to pollinate the stigma in the
flower?
Can I use other stamen from other flowers to pollinate the stigma in the
flower?
this morning, I had pollinated the flower with another stamen from other
male fl... 阅读全帖 |

发帖数: 16778 | 3 Pollinating seems a easy job, but is actually exhausting.
You need to climb up sometimes, or kneel down sometimes.
Some stamen in male flower are small, so you need to tape them inside
the stigma of a female flower.
Most boring part is their leaves make you allergical.
The pollen can make you allergical too.
Oh, I got some questions.
In some books, they show stamen and stigma in the same flower of plant,
for example,
1) does this mean there are stamen and stigma in the watermelon flower too?
2) ... 阅读全帖 |

发帖数: 16778 | 4 It is pouring now. No bees. So I have to take an umbrella to go out to
pollinate some watermelon flowers.
Although I used the same protocol for the pollination today, I noticed some
difference for the stigma and stamen. For example, it is difficult for us to
see
if the stamen has successfully fallen onto the stigma.
Anyone has experienced this in a rainy day? Can the artifical pollination
eventually succeed?
any suggestions welcocmed. thanks for your reading. |

Huh! That bumblebee looks ridiculous staggering its way
across those blue flowers, the ones I can never
remember the name of. Do you know the old engineer’s
joke: that, theoretically, bees can’t fly? But they look so
perfect together, like Absolute Purpose incarnate: one bee
plus one blue flower equals about a billion
years of symbiosis. Which leads me to wonder what it is

It is very strange.

What about your watermelon? |

Tomato flowers are stigma and stamen existing at the same flower.
So it doesn't need bees, but strong wind for pollination in natural
environment.
I use my electric brushtooth for pollinating tomato flowers.
It works great!
My method works for pepper too.
Good luck. |
