Biology of citrus is the book, I forgot where it was I just found this passage and took a print screen.Seems like there are cultural practices to make the citrus flower earlier and also the use of hormones, but it's difficult to find out how exactly as most are patented or kept secret by research stations.
Although considered "seedless", Oroblanco often produces two or three seeds. I've grown a couple of Oroblanco seedlings.
Did yours fruit?
If you cut these "early flowering" grapefruits after first year flower to just few centimeters above the soil level , they will again flower next year on the tops of the shoots emerging below the cut. Otherwise, they will flower in more than 10 years.

I successfully induced flowering in papaya at a young age. So I'll try same with citrus. I am not so sure about the size. from citrus cuttings I had flowers at 15 cm high Also I am still trying to figure out the Japanese methods.
Yes I know, papaya is whole different subject for which I made a lot of experiments.Thanks, I'll take a look at the article.
Don't you want to try to induce flowering?

Imagine, if you cut every year. What you will get in 20 years?
I get sterile male flowers on my key lime, this usually happens during the winter.This is a different methods. What I read it's more like leaving one vertical bud only and when it reaches almost 2 m high, bend it over.It's known that auxins and antigibberellins trigger early flowering in citrus, but not GA or cytokinins.So I guess bend it over would lower the auxins levels.
