It also could be a result of what plants were combined to produce the fruit in the first place. If someone used pollen from a different species of cactus, the resulting seeds could have characteristics of one or both parent. That's one of the perils of growing dragon fruit from seeds, is that you never know what you're going to end up with. The fruit itself is just the chamber the seeds develop in, much like the womb of a person or even an dog or cat. If you mate two dogs, say a Chihuahua and a pit bull, you never know what sort of combination youre going to end up with, or even if the pups in the litter will all have the same combination of traits. Dragon fruit breeding is the same. Every pairing can yield a slightly different result, even a combination of the same 2 parents can yield variations in what plants the seeds produce. Sometimes the result can be a near clone of the mother plant, or you could end up with some strange new (and not necessarily better) species. Its why the normal way to grow these plants for the common folk like us is the cutting. You know what youre going to get that way: the same thing as the plant the cutting came from.
BTW, theres a established thread on dragon fruit on this board, if you 'd like to join us there, and theres usually a bit of info being passed around this time of year.
Anyways, good luck with your plants.
