Yellow Zucchini Experiment 黃色夏南瓜授粉實驗
Purpose of this experiment: Can I save male flower pollen when I don’t have female flower ready yet?
As picture shown: 5/29 + 6/10 same plant male flower pollen, use Q-tip to swab and store in small re-sealable bag then store in freezer. This morning pollinated a same plant female flower and then cover female flower with clear plastic bag. In three days, this female flower will wilt and come off then we will know the result.
My Food And Flowers 
Curious to see this result. I have a few stamens in the freezer right now with the intent of doing the same thing.
I actually tried the 3 weeks old stored pollen from freezer and it worked!
This time what I did is to challenge older stored pollen and with plastic bag covered and sealed. so I know it is the result only from the old pollen I gave not fresh pollen from the pollinators delivered.
Wonderful news! Thanks for letting me know
You are welcome, glad to share the info!
