Tropical Fruit Discussion / Re: Brutal heatwave 7/06/18 in Socal

I donít waste fruit so I will just cut off the exposed pieces and eat the rest. It sucks that the Fruit cracked so early because they havenít sugared up yet. This first fruit only had a Brix between 14-15% depending on which side I tested.

The heatwave sucked! It killed back several of my new grafts and did this to my Dragonfruit.

Simon (and others), when you get multiple sprouts, do you separate and grow out each sprout individually? If so, how soon do you separate them?

I have some yearling PSM and NDM that I separated at birth and are doing well so far in terms of growth. Last year's PPK only kicked out one sprout but I am keeping it.

This year I got clumsy hands and snapped tap roots off seedlings and also feel I separated my two Coconut Cream sprouts too soon. I snapped one completely off the seed but I managed to keep its tap root. Have you ever done something similar and the seedling survived? Thanks!

Hereís a couple pictures of my Sweet Tart Seedlings. Two sprouts came up from this seed. I direct planted this seed into the ground. Just because two seedlings come up from one seed does not mean that one is zygotic and one is a clone. Also, sometimes one segment of seed will have multiple sprouts come up. Because those seedlings came from the same segment of seed, they should be identical. In this case, if you are trying to get a clone, you could be out of luck because the seedlings could have come from the zygotic segment.






There are a couple things I do to ensure I get two seedlings from different segments of a Polyembryonic seed. The first and easiest method is to sprout the seed and visually inspect that you have at least two segments that sprout separate roots. Once you have verified this, you can plant your seed with more confidence.

The second method is for seeds planted into a pot or the ground. Once the seedlings sprout and gain some size, gently tug on the trunk of one of the seedlings, if both seedlings move, they may be on the same root or the roots are entangled tightly. If the seedlings move independently, they are likely from different segments of seed.

Hereís a NDM seedling growing vigorously. There were 4 sprouts from this seed. One seedling is obviously dominant with the other three being very similar in size and growth rate so one can presume that the offtype is the zygotic seedling.




If I wanted the clone, I could remove two of the three smaller seedlings leaving the two seedlings with different phenotypes but I wanted to see how the four trees will turn out if left alone.

Hereís a couple pictures of some PiŮa Colada seedlings with multiple sprouts coming out.

Was that one of the varieties that Maurice Kong brought over to Leos place that we tasted a couple years ago? I remember Maurice brought over several samples of Mangos Iíve never heard of before at that tasting a while back.

Leo Manuel just notified me of these new introductions. I believe they were introduced by Maurice Kong but I am not positive. Has anyone tasted these varieties or have any information they can add.

Several people including Cielo, Kevin Foth, Bob Holtzinger,  Dr. Paulette Johnson of Tropical Fruit & Vegetable Society, Dr. Jonathan Crane at the University of Florida, Steve Pearson curator of Gifford Arboretum among others attended the special Mango tasting.

Maurice Kong introduced us to Ice Cream Mango and Po Pyu Kalay so I figure if he introduced these new varieties, they have potential.

CA Hockey, yes thatís the way to do it.

Future, thanks for the confirmation on Honey KISS being Polyembryonic, now to find some seeds!

Fliptop, I have separated seedlings from polyembryonic seeds before but I mostly do this for rootstock trees. When Iím propagating Polyembryonic seedlings in hopes of getting a clone, I leave all the seedlings. By leaving all the seedlings, i hope we that only one of the seedlings is zygotic and the rest are clones.

Some of the research articles I posted in another thread show that there can be more than one zygotic seedling arising from a Polyembryonic seed but it is less common.

I have a feeling that if we grow out enough zygotic seedlings, some of us will get lucky with a great tasting new variety. The Zygotic seedling should have about 50% of the genes from the parent Fruit or 100% if it was selfed but with selfing, there is still re arrangement of chromosomes so you will Not get a clone although you can get something almost identical except at the DNA level.

Fliptop, I have snapped off seedling sprouts multiple times and I have often gotten new growth from the tap root.

I love Ice Cream Mango. Itís very sweet and has a unique somewhat savory umami flavor that is hard to describe in words. I just wish the tree were larger and faster growing. It would also be nice if the fruit were larger.

Sometimes the tip of a cleft graft will spread open as the very tip of the cleft dries up. It can happen after 2,3 even 4 weeks depending on the stage of growth of the scion and rootstock and also depending on the variety of plant that is grafted.

Grafts on more mature wood of Pomegranate for example will sometimes spread open when the wood is older but on younger wood, it doesnít happen as often.

For soft wood cutting such as that using the stone grafting technique, I will often not use any binder other than parafilm or buddytape. The wood is so soft that it will not cause a breach in the parafilm or buddytape and the stretched parafilm or buddytape is strong enough to add enough tension on the union to provide more than adequate contact.

Is there any mention that itís been irradiated?

I would assume itís not irradiated if itís from Mexico but I canít say for sure.

I brought a few top notch Kesar Mangos in to work about two years ago and some coworkers mentioned that it had a floral or rose taste to it. Kesar is a very piney, strong Indian spice flavored mango but when it is at its peak of perfection with Brix about 20-21%, a floral taste does come out but I would say itís a stretch of the imagination to say that is specifically a rose taste.

Brewster Lychees do have a wonderful rose/Lychee aroma and taste!

Sucks I couldnít make it to help you graft today as I had previous arrangements with Leo Manuel.

I donít like to use rubber bands because they deteriorate rapidly in our hot sun. The clothes pins are so much easier to use. When I used to use rubber bands, many of them would go bad and release tension on the graft union.

For avocado grafts, which I havenít done too many of compared to Mango, I have had success with cleft, veneer and side grafts. The clefts are easiest but veneer seems to have slightly higher success rate, similar to side grafts. As long as you keep it warm and out of direct sun for the first couple weeks, you should get some good takes. The most important factors are the health and vigor of your rootstocks/scions.

Hey Future,

If youíve never had the Musang King, I would highly recommend it. Itís the best tasting Durian Iíve ever eaten. They sell for $10 a pound here in the USA but they are frozen although the quality is exceptional. The MK Durian is sweet with a very slight bitterness that is very tasty. I have not purchased a Mornthong after eating the Musang King a few years ago.

I was out of town for the heat wave so I couldn't adjust my watering or protect any plants.  I was told it reached almost 110 in Long Beach.  Amazingly only a couple plants got sun burned.  A couple of my blackberry plants wilted.  My Grumichama has burned leaves all over it and dropped a lot of fruit.  My two foot Sharwil Avocado also got burned badly.  A couple of my mangos got burned but nothing too bad.  And my Lemon Zest keeps dropping almost all its fruit.  They split and then drop off the tree but I guess that is for another post.

Bill

My LZ on Florida Turpentine rootstock did that for the first several years. After spraying it with a systemic Fungicide, it appears to be producing what appears to be normal Mangos without the cracking.

The temperatures have been very warm ever since the heat wave began and my plants are growing like crazy.

Quick update of my Emperor Lychee innarched onto seedling rootstock. It is pushing a nice small flush. The tree is in a very small tall pot and I need to up pot it but Iím going to wait till the flush hardens first.

If you donít fertilize or properly water the seedlings, they can take a year or longer to grow just a few inches. Hereís a picture of a giant Yellow Megalanthus plant that I didnít thin, rarely fertilized and hardly watered. This is a Peruvian strain and the parent Fruit was about 1 pound. I also grow the Ecuadorian strain. This seedling is about 3 years old!



If youíre in a more Tropical area, Iím sure you can get it to fruit in 2-3 years from seed but in a subtropical climate, Iím guessing it will take 4-5 years unless you graft the seedlings like what Brad( Spaugh) and I are doing.

Hereís a giant Yellow plant that was fertilized and watered properly.

Dragonfruit seedlings, especially the Yellow dragon are extremely slow growing in its juvenile phase. Once they reach about 3-6 inches, they start growing much faster.

Many of my Giant Yellow S\H Megalanthus seedlings started out with one branch but once they start gaining some size, they will form multiple branches at the base of the plant. I thinned out several of my seedlings to a few branches which seems to have enabled the remaining branches to grow at a faster rate.

It depends on your definition of ďBestĒ. For some, best may mean large, vigorous, disease resistant. For others, best may be small yet productive. Hereís a link with a brief discussion on Mango rootstocks.
http://tropicalfruitforum.com/index.php?topic=20816.0

Within the thread above, you will find links that discuss rootstocks with different attributes. Squam256, Dr Noris Ledesma or Dr Richard Campbell will probably have a lot more information if you contact them.

I hear that there are relatively new hybrid rootstocks that may be available soon that may be more disease resistant.

Itís hard to tell because I need to see more of the older leaves on the bottom and compare it to the new leaves on top but it appears to be lacking Iron, Magnesium, Zinc and Nitrogen. This combination is frequently associated with nutrient lock from use of hard tap water combined with chemical fertilizers. If you see white salt build up around the top waterline or the bottom drainage holes, that is another indication.

If itís been in the same pot for a while, it may require re potting.

Recently someone posted that E4 was Polyembryonic. I am trying to plant out a few top tier Monoembryonic varieties as well but Iím focusing on Polyembryonic varieties. With the Monoembryonic varieties, I plan on growing them out and then top working them onto mature trees. The remaining seedling can then still be used as rootstock.

Great, another mango I need to squeeze into my yard, lol. I have so much respect for the Zill family. They keep pumping out these great tasting Mangos selected for excellent taste. I canít imagin what the mango world would be like without all the great varieties they released. Thanks for the info Rob!
