Did you do anything to speed up flowering?

Thank you. Are they completely seedless?I think they have a few seeds, but could be mistaken.
I have them but not growing in the best of conditions so no fruit last year. The grapefruit is delicious. The lemon tastes like a lemon. The satsuma was good.Does anyone know more about this plant's background?What do you think of their other Frosts? Do you have them?

I have a question for you on this cross:Pummelo has mostly seeds from sexual crosses. It would be the female parent.
"Pummelo Siamese acidless x Poncirus (fast flowering or Poncirus+)"
I want to use the Banpeiyu for my pomelo since I have a large tree with fruits now so I can do it on the next flower cycle.
Which fruit do I get the pollen from, and which fruit will should be the female to hold the fruit?
I put 4 citrus and one olive tree in the ground last spring. I have been researching for about 2 years on how to get them to survive a winter by using 100 watts of electricity (a string of Christmas LIghts) along with plastic, styrofoam and wood chips. I am actually having a problem with them being to warm. Last night it was 16 degrees and inside my set up it was 62 degrees...as you look at my photo the trees are actually 2 feet below the level of the plastic. i planted them 1 foot below ground level and added 1 foot of wood chips. At 10 cents a kilowatt hr...my lights are running at 100 watts an hour. So basically 1 cent an hour to heat my setupThis may help: https://www.homedepot.com/p/15-Amp-120-Volt-AC-Thermo-Cube-Thermostatically-Controlled-Double-Outlet-TC3/100210525

Thank you sir! I'm so happy that recordings of the presentations are now being made. I have been 2 of these, and I was always annoyed when I missed one because I was late or speaking to other attendees...It great to be able to go back and find out what I missed the first time.
Does someone know what causes the leaf stem/veins to turn red like this?What is the current situation? Were you growing these plants under lights set for a long day and then changed to fewer hours/natural light? This occurred on some of my 3/4 poncirus hybrids. Change in day length appeared to turn plants dormant. Poncirus leaves frequently turn color before they fall.
It happens on some of my rooted poncirus cuttings:
3-3 and Curafora made trifoliate leaves after being crossed with poncirus. No idea how zygotic. The other two have never born fruit.Thank you for creating this resource.
10 Degree Tangerine 3-3 died at 9 F. -12.8 C
10 Degree Tangerine 2-2 survived
CiClem 10 is approximately as hardy as 2-2
Curafora barely survived
Thanks! I'll get those added once I'm back at my computer. Any idea on if any of them give much zygotic seed?
Part of my motivation here is the fact that precious few cold hardy citrus also produce mostly zygotic seeds. There are a lot of hardy citrus, but almost all of them are basically dead ends when it comes to breeding. Identifying the ones that are both cold hardy and zygotic, and creating a reference for them, is something I've noticed is weirdly lacking on the forum and on the internet in general.
