Tropical Fruit Discussion / Corynocarpus cribbianus
« on: September 18, 2018, 03:50:36 PM »
Anyone know anything about this fruit?  It evidently occurs in Aus, PNG, & the Solomon Islands.  Since rare fruiters like Mike T do not seem to have mentioned this (couldn't find in google search), I am assuming it is not worth attention.

Tropical Fruit Discussion / Mango graft problem
« on: August 21, 2018, 02:49:21 PM »
I have tried to graft some mangoes the last couple of years & have had very poor success.  I have been using cleft grafts & used to get very good results on temperate fruits, ornamentals, conifers, etc but I have not done well with mangoes.  I have been using rubber bands to secure the grafts and buddy tape to cover the scion & area near the graft.  It is possible that my eyesight is just gone down hill enough that I no longer line up the cambiums well enough but I don't think so. 

One thing I have noticed is that the scions tend to look like they are developing sooty mold (or something that resembles it).  Unfortunately, I neglected to take any pics.  It is not present on any of my trees or anything nearby but this is the Hilo area & fungus & other microbes are everywhere.  We do have a humid environment here but I am guessing that I still need something to insure that the graft area does not dry out initially.  I have not tried hydrogen peroxide or dilute bleach to sterilize the scions -- maybe that would be worthwhile.   Anyone encounter anything like this?  Any ideas?  I was thinking about trying to use a loose fitting plastic bag with a few small holes in it taped to protect the graft area from drying.

Tropical Fruit Discussion / Rust on Myrtaceae in Hawaii
« on: May 24, 2018, 04:35:03 PM »
I've been wanting to post this for a little while but I have been waiting since I think Oscar would be the main respondent and I know he has had a stressful period with the volcano activity.

I have seen a pretty wide range of response of various species in the Myrtaceae alliance to our rusts here in Hawaii.  Many (so far) seem unaffected but a couple are really struggling.  Cedar bay cherry (Eugenia reinwardtiana) seems to be one that is having a tough time.  I have one tree of onionwood (Syzygium alliiligneum) that is growing like a trooper while its neighbor is now pretty severely stricken (greatly slowed).  So far, it has been a while and I am not seeing this second tree affected so perhaps this particular tree has some natural resistance.

I live in an area where there is a solid reservoir for this rust.  There are tons of rose apple (someone originally told me that they were mountain apple but I now hear that they are probably rose apple) in the palis that are severely affected (they "kind of" grow, slowly and weakly, but I have never seen fruit on any).  Unfortunately, it is all around in the area so there is no way to eradicate them.  I'm sure that there are others in HI in the same boat as me.

Can we start a list of Myrtaceae that are wise to avoid in Hawaii for rust susceptibility?

I just wanted to doublecheck, I think I had read here that mango & kuini are graft compatible, correct? 

Thanks!

Temperate Fruit & Orchard Online Library / Cyclopedia of Hardy Fruits

I came across this pdf.  Seems like a good reference for some older clones that are now sometimes pretty obscure:

Tropical Fruit Discussion / Bakuri seed prep (Platonia insignis)
« on: December 04, 2017, 02:19:43 PM »
I've got a question I am directing to Oscar of FL but others may have the same question so I decided to post here.  The seed packet has instructions to "first soak seeds in distilled alcohol for 10 minutes".  I am assuming that this is ethanol ("drinking alcohol") not isopropanol or methanol.  I also assume that denatured alcohol would not be appropriate.  What percentage / proof should be used?  Could a relatively neutral high proof spirit like vodka be used?  (I can think of good ways to use the left over alcohol in that case.  :) )

Thanks,
John

Info on some monkey colas, where the aril is eaten instead of the nut:

Tropical Fruit Discussion / Annona paludosa
« on: July 09, 2017, 01:08:00 PM »
Anyone fruit this yet?  Just wondering how you know when fruits are ripe on this one.  I assume they perhaps start to yellow a bit?  It looks like they get to about the size of a large strawberry or perhaps a bit larger.  Since it is often compared to a small soursop, I assume you pick when still a bit under-ripe & allow to ripen on the countertop?
Any advice is welcomed.

Citrus General Discussion / Budd blood orange
« on: April 05, 2017, 02:58:08 PM »
I don't recall hearing of this one earlier, does anyone know anything about it?  How does it compare to better known blood oranges?  Does it require less chill to develop good color (it supposedly originated in FL)?

Here is info on it from a nursery:

I figured I should list this here, since people may not find it in the general discussion forum.  Paul Noren's presentation from Kona (Dec 2016).

Tropical Fruit Discussion / Zevelu - Diospyros mannii
« on: December 19, 2016, 10:36:52 PM »
This fruit sounded very intriguing (& very good) in the Congo Native Fruits book.  However, reports I had seen since from Aus gave it bad reviews.  Paul Noren reports he has never tasted a worthwhile zevelu, however, Roy Danforth did have some exceptionally good ones at one point.  So, it sounds like this is a high risk fruit if you get seeds.

Tropical Fruit Discussion / Panda oleosa
« on: December 19, 2016, 10:33:21 PM »
This fruit sounded interesting in the Congo Native Fruits book but Danforth & Noren indicated that they did not know how to germinate these seeds.  There is now an update to this, the seeds require no special germination procedure but may take 8 yrs or so to germinate.

Just wondering, do sweet lime cultivars come true from seed?
