The Tropical Fruit Forum

Thanks TFN. Where do you purchase the frost cloth?

Thanks for the temperature listing! It helps paint the picture of how hardy the tree is. Maybe breaking above freezing each day helped give Super Changsha some relief. Like being able to get it’s head above the surface of water to take a breath during a week-long swim in a frozen lake.

How many hours below freezing did it endure during that event and still be able to survive and set fruit this year?

Another link about treatment of phytophthora.

I looked up “Kabosu “ or citrus sphaerocarpa on Citrus pages site. It’s Ichang/sour orange hybrid growing in China and popular in Japan.

But Walt, it sounds like everyone can concur that the “poncyrus is bitter gene “ is present in all human, and probably all vertebrates’ DNA. I’ve heard even pigs won’t eat trifoliate fruits. I wonder if goats will; goats eat anything.

Thanks guys. So, when describing the hybrid the mother plant is listed first? Ex: poncirus trifoliata ( mother) x citrus reticulata (father)?

I should know the answer by now, but I know several of you can elaborate ad nauseum and enlighten me: When trying to create a citrus hybrid, does it matter which of the parent trees serves as the mother or father plant? For example, I’ve learned Ichang papeda doesn’t come true from seed, so if I want a hybrid of ichangensis with Seville sour orange, I would want the ichangensis to be the mother plant, no?  If the sour orange was the mother pollinated by ichangensis, there would be less chance of getting a hybrid offspring since the orange is polyembryonic, right? So when the citranges were created via hybridization, which was the mother plant, the trifoliata or the orange? Did it matter since oranges and trifoliata both tend to come true from seed with low chance of producing a hybrid? Could I pollinate both parents with each other’s pollen and then watch the seedlings of both sets of fruit to look for hybrids?

Thanks hardyvermont. Same idea as adding some apple or crabapple to rowan jelly.

I’ve not sent him a personal email. Guess I should. Thanks. I really think it’s Swingle though. After research, I think the only way it could be poncirus x aurantium is if the aurantium half was bergamot since they can be yellow and pear shaped. I wonder if anyone else has got any fruit off of a Woodlanders “citradia “.

Lovely. Morton and citrumelos are rather large fruits compared to other citranges. May this combination of the two produce larger fruit in the future?

Poncirus  juice extracted yesterday and darker juice settled to bottom overnight in refrigerator. Top layer tastes very bitter but may be able to drink small amount with added sugar.
