Thank you for your thought. I agree that organic soil does break down over time and the soil level gets lower. I think that is the best situation to add more organic soil on the top without overflowing. Dragon fruits are shallow rooted plants. When you add more soil on the top, very soon, you can see new roots growing in the top soil layer. The recovery of the declined plant is not only relying on the air roots from the top but also new roots growing from the bottom . Using sandy soil is a good idea but it still needs time to verify its long-term effect. I am doing experiment to verify it too in the meanwhile.

Thank you. I am so glad to hear your successful story.

The genetic calculation does not specify RR x KVA or KVA x RR, meaning the hybrids produced by either crosses will have the same probability for the hybrid variety. Besides, there will be so many variation in each cross, it will be very difficult to compare the differences between the two crosses, so it will be a lot of work but hard to get conclusion.

As far as I know, Selenicereus megalanthus, such as the yellow palora dragon fruits are tetraploid. I have tried to pollinate diploied dragon fruit with it to create triploid dragon fruit with some success. This is the video showed some of the process: ua-cam.com/video/ev4ZW78JjFs/v-deo.html

No creating polyploidy using anti-mitotic agents

@@xiaoli2142 I'm aware of megalanthus tetraploid but undatus and polyrhizus can also be converted into tetra or octaploid

@@justhackitfpv No. I haven't tried anything like that.

@@justhackitfpv It may need tissue culture technique and a lab to do so.

KVA is the mother of RR, so half of the chromosomes of RR are from KVA, so they are genetically very close to each other, which could trigger the self-sterile mechanism when you using the pollen from RR to pollinate KVA. I always wondering how the self-sterile occurs. As far as I understand from readings, that when pollen pollinate a flower, many tiny pollen tubes will form along the stem of the stigma to guide the germ cells travel to the ovary. When self-sterile occurs, the plant produces enzyme in the stigma stem to block the formation of pollen tubes from its own so that the pollen from itself will not reach the ovary, while pollen from other varieties will resist these enzymes so their germ cells will travel through their pollen tube to fertilize the flower. So, if RR inherited the pollen tube formation genes from TC instead of KVA, it will form TC type of pollen tubes instead of KVA pollen tubes, which will allow these pollen tube resist the enzyme from KVA so it won't block the pollen tube formation, therefore allowing it to complete the fertilization process. I am just guessing, I am not sure if it is the true mechanism.

@@xiaoli2142your knowledge in this subject is impressive! Do you think there will be any difference in the resulting seed traits if you take pollen from plant A onto a flower of plant B versus pollen from plant B onto a flower from plant A?

@@codyj7769 I think it won't have much of a difference in either scenario. The chromosome segregation and recombination would be the same but I can't rule out the influences of the mitochondrial DNA and the proteins that are involved in this process. I tried to do an experiment just like this, to use pollen from Bruni to pollinate Sin Espanis and vice versa, then I realize that there will be so many variations in each cross, it will be very difficult to compare the results from the two scenarios, so I kind of abandoned the experiment.

The pollen was air dried over the counter at room temperature for 24 hours before freezing. It is easy enough and good enough for pollinate of dragon fruit flowers from the same growing season. To pollinate the flowers from next growing season, I have tried to freeze the pollen with silica gel pack, hopping that the silica can continue to dry the pollen further to preserve its activity, but I have tried twice. None of them worked yet so far. The method still need some improvement. Do you have a specific way to dry your pollen?

@@xiaoli2142 I pollinated 13 flowers today and vacuumed up all the pollen. I now have a couple grams of pollen . It will be my first experiment with freezing pollen. Thanks

I am at 9b, central Florida. Yes, I agree. Different climate may have affect on the timing of effective pollination.

I have a small farm, mine are self pollinated and we have bees to pollinate. There are 9, 10 bees inside every flower.

@@beinginsan460 Yeah, the self pollinating dragon fruit can save a lot of time, but unfortunately, most of the varieties are not self pollinating. What variety are you planting in your farm?

I opened the dark looking fresh and I can see clearly that there are many seeds have already formed, but something infected the flesh and the flesh turned black. I am hopping the next flower will have better luck.

Hi, thank you for commenting. I don't remember I said the parents are "bitter". Their parents are Bruni and Sin Espinas. Both of them are NO bitter, but just not as sweet as I would like them to be. ha ha.

No, the parents are not bitter but just not very sweet. My Bruni has a Brix reading around 15-16 and Sin Espinas has a Brix reading around 14-16. Some other people reported Bruni can have a Brix reading around 17-18, but mine are not as that high.

Surely hope so. Thank you for your comment.

Thank you very much. I am hoping for a better tasting fruits too, but because both parents are not very sweet ones. If the test shows these are sweet, that would be a very good surprise.

Thank you for the comment. The flowers are pretty but I am looking forward for the fruits too to see if they are worthy to save.

Also, seeds from hybrids like these will not come true with the specific features, so if the taste test shows any of them are good, I will try to grow up more branches to propagate them.

I am testing if the soil is bad by putting some new plants in the pot with old soil and also leaving some old plants in the same pots. It seems that all the new plants are growing well in the old soil and some of the old plants recovered in the same pots arguing about the bad soil theory. It may still too early to draw conclusions but we will see. Thank you for commenting.

Thank you for your comment. Interesting that turning the pot 180 degrees can awaken the root. I may try it some other time, but this time, I just want to see how the plants handle the bad situation such as root problem. Neon and Pink Panther are very similar varieties, but Pink Panther growing more branches from the main branch but Neon only growing flower buds. I would like to see this process going through without interruption to see what is going to happen later. Since I have the Sugar Dragon re potted and Neon is basically the same as Sugar Dragon, so I will not lose the variety if Neon will not recover.

Thank you.

Thank you very much for watching my video and liking it and thank you for your subscription. Happy gardening!

It depends. The fastest one take 12-18 months, but some can take as long as 2 years to fruit, so if you treat them good with good sun shine and good fertilizer, it will fruit earlier.
