Citrus General Discussion / Okinawa
« on: June 16, 2023, 03:42:54 PM »
Just wanted to alert that Kamado has posted about an upcoming trip to Okinawa in Buy Sell Trade.
Not sure if any members would be interested in some of the wild Citrus species previously discussed.
Obviously only members in areas not subject to Citrus import bans.


June 08, 2023, 12:05:18 PM ťOn a different note, I will be in Okinawa next month.
I can get a variety of fruits, so message me if there is anything you want!

Have a great weekend!

Tropical Fruit Discussion / Re: Electroculture

Not sure how this may link in.

"The soil in your garden is paramagnetic. It isn't magnetic, but mildly attracted by a magnet and partially aligns with the earth's magnetic field, making it paramagnetic. Some soils are attracted more than others, and the more paramagnetic your soil is the better."

Volcanic rock crusher dusts have been investigated to increase this property in Agriculture.

I am not sure I would follow conventional science when it dismisses concepts too quickly.
If we look back at Science over the last 200 years, it has evolved greatly, and at any point in time many prevailing concepts have been proved incorrect later on.
Some seem ridiculous now, yet they were mainstream science back then.

My neighbour has a grape farm.
Each row of grapes has a railway line post at each end in the ground ( earthed ?? ) and 3 strands of steel wire, 150 m long between, held up by wooden posts ( insulated ? )
He has 10 acres of this set up, and other neighbours have 5 or 6 strands of wire running between similar set ups. Some have metal star picket stakes instead of wooden posts.
Apart from the grape vines, it kind of sounds like a giant antennae or crystal set. A set of old style telegraph lines ?
Is it possible that this structure is exerting some kind of weak electrical field on the plants ?
I'm not sure either, but the neighbour is certainly under some unusual influence.

Well if it proves to be right, and your flowers grow better,
You might be saying,
What in Carnation ??

Citrus General Discussion / Re: one person's trash...
« on: June 13, 2023, 10:39:21 AM »
I often buy 3 paks of Tahiti Lime for $1 or $2 when discounted at the supermarket, fruit is on the way out.
So far I don't think I have found 1 seed in those, ( Did get some from free fruit home garden trees, possibly pollinated by another Citrus ? ).
Still haven't given up on those 3 paks, but have stopped buying them at $2 or more so much.
Have to confess that "I brake for roadside Citrus fruit " for seed.
These are often from people taking prunings to the tip or dump, and fruit drop off the trailer.
Sometimes travellers dump fruit on the highway before they cross state borders.
Nothing too unusual so far, but you never know what might be hidden in someones yard ?
Since fruit fly became established here, more and more fruit trees are getting the axe ( chainsaw ).
A lot of older trees are being lost for this reason, and also when houses are sold and renovated, fruit trees often get removed.


55
Anybody think this is a harvest issue ? Fruit was picked too early. Sometimes happens with fallen fruit after storms ??

Tropical Vegetables and Other Edibles / Re: ISO: Pandanus conoideus
« on: June 12, 2023, 02:32:24 AM »
I have seen a few amazing Australian native Pandanus fruit in FNQLD, but this one is even more so.
Have you tried reaching out to the PNG community in Cairns, they always had interesting vegetables at the markets when I was up there.
I hear the market scene has changed a lot nowadays, so may not be as easy as before.
Certainly hope you can track it down.

Tropical Fruit Discussion / Re: Rooting hormone for graft success?
« on: June 11, 2023, 01:54:37 AM »
Not sure about the rooting hormones.
I have heard the that GA, Gibberilic Acid can be used to force lazy buds that won't sprout.
Etiolation, ( removal of light sources ) is also sometimes use in grafting.

58
Some more, great!

Thanks for the addition of the Jamaican cultivars. Can see if I can find some.

Those 3 are in the " Rare Fruit " circles in Au.
Topaz ( Ortanique ) is a commercial variety, fruit sometimes in the supermarket.

59
Other PNG Citrus are the Papuan Citron and Citrus macroptera ( related to kaffir lime / makrut ).

Ugli, Temple and Ortanique are Jamaican in origin. Ortanique is also known as Topaz here.

King ( King of Siam ) mandarin is from Thailand, and other related types from Vietnam.
Many of the original parents of modern Mandarins and Tangelos are from S E Asia.

60
You make a good point, but in this case the disease did come from China.

Makes sense if Citrus came from China. Some of the species evolved there. Pest and Diseases also.
Some modern cultivars are even called Mandarins !!!

It seems most of rutaceae can host psyllids and many can get HLB, but it doesn't seem to do anything to them. HLB seems to specialize in mainline citrus.

Murraya is a very popular ornamental in Australia, and also a potential problem.
Many other wild Rutaceae, like Microcitrus, Acronychia, Flindersia, just to name a couple.

This last winter with extremes and days of extremely warm weather confused some of my mango trees.

Similar problems here in Australia in some places. I have Apples and Fig fruit ripe on the tree in winter.
I get around a bit to peoples yards for work, and there are a lot of figs with extra crops this year.
Orchard growers were complaining that the stone fruit season was way out, and varieties were going to miss the Xmass sales window.
Also variety ripening  times were overlapping more, causing a glut, instead of a stretched season.
A mild wet winter also brought fungal problems, and fruit fly surviving thru winter to kick off their attacks again.
Grapes had similar problems with fungus and delayed bud burst and flowering, then summer rains and mild weather slowed ripening down again.
Many grape crops were a write off.
This type of situation did happen in the past, but if it occurs more frequently and repeatedly in the future, it will be the end of some farms.
The success of this area is based on being in a dry semi arid climate, hinting into subtropical.
Irrigation from the Murray River allowed water to be applied in a controlled timed fashion over normally dry summers.
Rain events during fruit ripening season are not welcome in most cases.

Our local Catholic Priest ran 2 churches, one in the irrigated grape and citrus area, and another in the grain growing area, about 50 km apart.
On any Sunday, he would be praying for rain in one church with one parish, and praying for no rain at the other church a few hours later.
At some point in the year he would swap the prayers around, so that the fruit farmers got rain, but the wheat farmers did not get any during their harvest.
Some people blame Climate Change for recent weather events, but it is interesting to note that the priest did eventually retire,
and the parishioners merged and did start all using the one church ??

Huanglongbing, China? Seams like there's some bad stuff coming in from China lately... Or maybe I am just to cynical..

Maybe a leap too far ?
Huanglongbing is just the Chinese name of a widespread Citrus disease.
I would be more inclined to blame the Romans. So many plant and animal disease organisms have Latin names !
As for Huanglongbing, it is more commonly known as HLB. Blame the Corporations ?
Interesting that the Australian Citrus species have resistance to HLB, even though we don't have the bacteria that cause it or the insect vector.
Maybe something carried from the ancient past in the plant genes.
A very strong case for the conservation of ecosystems and plant species.
Who would have thought ' Finger Limes " could be so important to the future of the Orange Juice Industry ?
You never know what else you may need from wild plants in the future ?

Tropical Fruit Discussion / Re: cultivars, nobody knows
« on: June 04, 2023, 09:41:28 AM »
They looked at me like I was an idiot when I asked them what variety of Jackfruit it was.  Based on taste and appearance though I'd say they're selling multiple varieties.

How about the style or flavour of Jackfruit, ie crunchy, bubblegum, orange etc Maybe exact named cultivar is too broad.
For some fruits, the country of origin may be meaningful to people from other cultures ie Thai, Vietnamese, Cambodian.
They would know well the fruit types from their own country, and those from neighbouring countries in SE Asia.
Possibly Durian is the exception where named cultivars are known and sought out.
I have always found that a knowledge of fruit and interest in other cultures around fruit to be a genuine point of contact, even if I too look like an idiot at times.

Temperate Fruit Discussion / Re: Chilean Nut trees - Gevuina Avellana
« on: June 03, 2023, 04:24:19 PM »
Geuvina is in the Proteaceae family, and in the group with Macadamia.
You could investigate Macadamia growing problems, or Proteacea problems and the solutions.

Tropical Fruit Discussion / Re: Happy donut day
« on: June 03, 2023, 04:12:43 PM »
Krispy Kreme came to Australia about 10 years ago. It was a big hype at the time. They are sold about 100 km from here, so we sometimes get them if we are going past.
Australia also has food vans selling hot strawberry jam filled donuts. They are flat tennis ball sized, not donut shaped.
( After we closed the Hole in the Ozone Layer, we then closed the Hole in the Donut. ).
Pineapple icing glazed donuts from 7-11 were very popular, especially with pot smokers with the late night munchies.

66
I have tried 3 wild Australian Garcinias. I like G. warrenii,  (sour but a lot less than the Yellow mangosteen.). No others I have tried are much like " The Mangosteen ".

67
Thanks W. that is interesting information. Any more info about what is in the collection ?

68
One of the Australian collections has about 10 different distinct Pummelo varieties, and well over a hundred Orange varieties.
In the Oranges, a good number are Navel Orange varieties ( Late Navels, Limb sports etc ) and a lot are Valencia selections.
In a way " more of the same ".
That leaves less than 50 % unique Orange varieties in the collection.
It would possible to have a very diverse Citrus collection, with lower numbers in the collection.
Or a very large collection with less unique / diverse varieties.
I am sure that many members on this forum have highly diverse and unique Citrus collections, with some varieties not widely known or represented elsewhere.

69
It would certainly be interesting to get the Arboretum list, and which organisation it disconnected with ( or private collection ).
https://tahititourisme.pf/en-pf/activities/points-of-interest/arboretum-papua-keikaha-ua-huka-en-en-pf-3438682/

quote
A tree nursery with different varieties of fruit and forestry trees and a genetic resources conservatory of citrus fruits, including a hundred or so species from Corsica.

Maybe it is part of the Citrus research based in Corsica ?

70

How can this statement be true? The largest collection of Citrus fruit tree's in the world are at an Arboretum on Ua Huka Island , Population 674 , in  the Marquesas Islands? Hmmmmm


https://tahititourisme.pf/en-pf/islands-and-archipelagos/marquesas-islands/ua-huka/


Maybe the 674 people each all have a different Citrus tree ??

71
Yes definitely Juvenile leaves, and long and strap like, as usual for C. australis.
Being in Australia, I have collected and grown some seed from the wild around Brisbane.
Can't say I have had seedlings that look exactly like those in the pics.
Also have a feeling that the leaves should be slightly more pointed than round ended.

72
They do look a little unusual. Are they under strong grow lights that could compact growth/ short nodes ?
Each individual leaf looks a little different to the australis seedlings I have grown before.
I will double check some of my seedlings for leaf shape.
You could try tasting a leaf from the seedling and the seed tree to see if there is any strong difference indicating a hybrid.

I don't think Jordan Peterson should be in this section "Tropical Fruit Discussion".
He really should be in the " Temperate Fruit Discussion".
along with all the other nuts.

lmao!

Just out of curiosity, if the OP of this thread had instead posted some pictures of yellowing citrus leaves and asked "is this citrus greening" and the first reply had been somebody saying that citrus greening was a conspiracy theory by Big Mango, and then people here had correctly called them out for being chock full of crap, you wouldn't be calling for the thread to be frozen, would you? Honestly if that were the original exchange, the responses in here would seem kind of tame, eh?

Just because something has unfortunately been politicized, doesn't mean that it isn't extremely relevant to what we're all trying to do here, i.e. grow fruit trees.


We don't have Citrus Greening in Australia  as of yet.
How might it get here ?
We are still importing Citrus fruit from USA. Possibly low risk / zero risk with treatment, but who knows.
Australia exports Citrus to USA in your off season, and imports in our off season. The Gap is not that great. The profits must be bigger.
A few years ago exports of Citrus to USA took a dive. The local industry went into local promotion and begged locals to buy local Citrus fruit.
Funny that they didn't ask that previously when they could sell their fruit overseas ??
Citrus canker got into the Darwin area some years back. Suspected by contaminated tools from farm workers who came in from overseas farms.
Another outbreak linked to illegally imported budwood used to start a major orchard in QLD.

Not a "conspiracy theory" as such  but the global movement of produce and workers is linked to the economic forces that further contribute to Climate Change,
above that of each persons individual consumption of goods and services and contribution to the atmosphere.
This was clearly illustrated during Covid, when supply chains went to near breaking point. Goods could not easily be moved interstate.
Another interesting case was here was when a disgruntled worker put sewing pins into punnets of strawberries. ( ps this is a strange case, want really happened is murky).
Basically the whole supply of Strawberries in Australia was shut down because they all come from 1 or 2 large farms in QLD, and trucked Australia wide.
A similar case with Canteloupe melons, Blueberries etc. Totally shut down due to contamination issues on one or two farms.
Local small scale producers of fruit and vegetables cannot often supply their local supermarkets.
It is well known that fresh grapes from this area, travel to Melbourne for supply/logistic reasons, then travel back to our shelves.
If tackling Climate Change addresses some of these issues, it will be a good thing.
