• atemoya: Lisa and "unnamed Mauritius"This unknow cv. from Mauritius (well at least i can tell it got into Reunion from Mauritius...) is a self fruiting cv. It has very sweet and nice flavor. see the link below to a topic i had launched about it http://tropicalfruitforum.com/index.php?topic=10299.msg131957#msg131957
• cherimoya: El bumpo
• sugar apple: a vietnamese cultivar very sweet and tasty with interesting seed/flesh ratio (see the attached pic from a 1st year fruiting tree, i assume the trees can come bigger if hand pollinated and from an older tree).

To further illustrate what already has been written, I like to try different rootstocks on my own experimentations. It looks like we have too many variables at play. The growing conditions and the climates may be different.

For example, I grafted several cherimoyas scions onto cherimoya rootstock whose seedlings were from the same mother tree.  None of them took.

I grafted 2 cherimoyas onto graviola (annona muricata), and both of them took, and both of them are growing like a weed.

I have read that graviola (annona muricata) was not a compatible root stock for cherimoya! Did a read it right?   

My understanding is that biriba (rollinia deliciosa) is being used as a root stock for graviola (annona muricata) successfully in northeast Brasil. The resulting tree is resistant to root rot and to other diseases.

Bottom line, in my opinion,  is to try yourself several different rootstocks for atemoya.  You may be surprised with the results.

Well done micah it sounds like I sent keledangs seeds to Hawaii for nothing. I understand there is a bit of variation in this species. It would be interesting to compare the fruit to pix I posted.I know they can be picked 'green' and ripened off the tree.They are prone to dropping and getting splattered if tree ripened.

There has been a relatively new atemoya  cultivar released in Australia, called "Tropic Sun". They are marketing this as an "ideal backyard" tree. I am assuming they have grafted this onto A. Squamosa  rootstock for the dwarfing characteristics.  It's not the case with mine that's for sure, mine are definitely grafted onto Cherimoya. I believe they have at least two rootstocks to cater for temperature differences in the country, A. Squamosa for tropical Australia and A. Cherimoya for the rest of us.
 In summing up, if A. Squamosa is plentiful in your area, you could consider marketing it similar to above, or do you have any restrictions on importing Cherimoya seeds into your country? One last thing, it would only take three/four years to get a producing Annona tree there anyway for your own seed production.

What kind of graft is used on these grafted soursop?   

How long they take to bear fruit?

Thanks,
John

Your place looks great Samuel. I like the way you are going about things.
And Simon is killing it with the pick axe in that picture, reminds me of myself out in the bushes with sandals and tools, making it happen.  Keep up the good works.

Upon rereading the FTBG webpage, I read that though the trees are dioecious, grafted females can produce without males nearby.  scientifically speaking, How is this possible?  Also, if one uses a male seed unknowingly as rootstock, will that effect the fruiting of the tree?  I suspect it will not but haven't read anything on here talking about it.

Thanks!

The sex of the plant will be determined by the scion, just like the cultivar will be determined by the scion. The rootstock, that is the trunk, is not going to flower, so it will have no sexual parts.
About fruiting without pollination, that is called parthenocarpy. A lot of garcinias, including mangosteen, which are all female, are able to produce fruit without getting pollinated. The act of pollination is to form a seed that has genes from both parents, not really to form the fruit (pulpy part that we eat). So the so called seeds in these parthenocarpic plants are not real seeds in the sense that they have genes from both parents.
