The Tropical Fruit Forum

Like russians developed many pomegranate varieties that can handle much colder temps than temps they are originally exposed to

Can you do the same thing with loquat?
The only issue that comes into mind is that they start flowering in december so unless it mutates to flower in spring instead its not gonna happen

But it makes you wonder about the possibilities of zone pushing

...than temperate climate trees?

Its as if tropical fruit trees are unable to "do the work" of bringing flowers, leaves at lower temps whereas temperate trees (apples, plums, apricot, pears etc.. ) do that with ease..
What is the science behind this?

Interestingly enough it not only affects tropical fruit trees but non-tropicals as well that came from the tropics, subtropics (but somehow evolved to handle colder temps eg: Asimina Triloba). They are really starting to wake up once night time temps go above 10C/50F

Can it be that as science advances we'll be able to manipulate whatever that is causing it to wake up early (and thrive), or push it with selective breeding?

.. by approach grafting it onto another seedling?







As you can tell the main stem is drying out, Im wondering if humidity would help it to recover or its heading for certain death?
It started a few days ago, now Im thinking approach grafting it would be the only way to save it (newly formed stem)

(BTW the seedling is not moldy it simply looks brown when its young)

The small ones in the picture?

Ive read that with approach grafting you have less chance for graft incompatibility to occur
Does that only include cheimical incopatibility (virus, fungus attack) or when a more genetically distant scion is used?

To be more concrete...  would it be possible to graft avocado on red bay this way? (Both are in the lauraceae family)

I have a few seedlings from store bought avocadoes and some of them have features like

• anis smelling leaves
• and the newly emerging ones are red colored

The weird thnig is that as far as I know there arent many actually Mexican avocadoes in the store yet these definitely inidicate Mexican origins

So how can this be? Is this even a legit claim that red and anis smelling leaves are an indication of cold hardiness/Mexican origin?

Saw a guy on Youtube talking about how you can plant a bunch of seeds from the supermarket outside in Zone 8-8b, maybe give it protection when it falls below minus 1-2 C. (and you can push it further as it grows )
And if it survives then you've potentially created a cold hardy avocado rootstock (Regardless of the origin of the seed)

Now you have to work with a large number of seeds, maybe only one in every 10 survives

Is this legit doable? Im starting this experiment, just wanna get some insight from someone who might have succeeded already
