Citrus General Discussion / Re: Lights for citrus trees
« on: Today at 03:19:03 AM »
Just a guess question,  but any risks in removing the covers, from water, insects, humidity, dust ?

I wonder if those Brazilians got those Finger Limes ?

Since they have adjacent natural ranges there is a possibility they have a common ancestor. In some cases of near relatives, the grafting method may need to be tuned to work ie approach grafting of two rooted plants, or leaving some live leaves or branches on the rootstock. As for the two species, do the flowering and fruiting times overlap to allow X pollination ? Also is there anywhere in the ranges where they meet, and possibly hybridise.
The other one I was thinking about was Diospyros sonorae from Sonora.
Seems to be in your ball park too.

Just for interest here is Diospyros mabacea, Red Fruited Ebony, now one of the rarest rainforest trees in NSW, and a few other Australian species.https://keys.lucidcentral.org/keys/v3/FFPA/key/FFPA/Media/Html/Ebenaceae%20Images.htm

Cold Hardy Citrus / Re: Poncirus from Seattle Arboretum
« on: Today at 02:43:09 AM »
If you have other Citrus you could graft/bud the Poncirus onto that, or grow some Poncirus seedlings as rootstocks.

Diospyros is a very big genus, and the species occur in Australia, PNG, South Pacific, SE Asia, India, Africa, Americas off the top of my head.
There is a possibility that two species are closely related enough to be graft compatable, as well as the chance that they are not.
Some of the Australian Diospyros seem similar to D.kaki, and some quite different looking plants.
Kaki can graft to D.americana and D.lotus so cross species grafting is a possibility.
From what I have seen D.texana seems fairly different to D.nigra, but that may not mean they are not in the same sub group ?
Maybe it is worth the experiment ?
I have not heard of D.texana being used as a rootstock for D.kaki, which would seem a useful combo in some areas ?
I believe there are also other Diospryos from further south than Texas.

Citrus General Discussion / Re: Thornless Mexican Lime
« on: November 27, 2022, 03:00:03 PM »
The Bearss / Tahiti Lime is thornless. Most Mexican / Key Limes are thorny, except thornless selections. There are some bigger fruited selections of Mexican / Key also.
For many peoples tastes, the one you have is the true lime, and the Bearss is a very very close second flavour and fragrance wise.

$18200 AUD is the no payable tax threshold, anything above that is taxable.

That is the income tax threshold.

The $5000 is the threshold for income from a Hobby before it becomes a business. So if you sell 4999.00 of bonsai trees you can regard that as a hobby without declaring that as income added to your $ 18200. ( I think that is more like $ 20000 now or soon.)
If you register for GST you can claim back against what you have paid and balance that out. The 70000 threshold is voluntary, you can register before that income but for some it is not worth the extra paperwork and compliance and paying 3 monthly instalments.
As you say the AU Govt has pushed itself into the online commerce area and the platforms like e bay and pay pal collect the GST for them, probably because it also ramps their cashflow too.

I think you can fine this pear at Korean market.
Bacause it is normal pear in the South korea.

I got some really nice big Nashi Pears at my Vietnamese grocery, the fruit came from Korea. Sorry, I don't know the name for Nashi in Korean.
Also got Ya pears from China a few years ago. Not exactly the same as Nashi.

Tropical Fruit Discussion / Re: Jack Bean for Nematodes
« on: November 25, 2022, 08:02:19 PM »
Since radishes are in the Mustard family, the nematode action could also be chemical, as with these Brassicas.
https://www.thelostseed.com.au/mustard-mix-nematode-control
There was a product over here based on mustard seed powder as another method of bio fumigation.

I was hoping the study with potted plants could be applied to in ground plants as well.

OK please keeps updated on that investigation.

Another possibility in the marigold area is Tagetes minuta as a green manure crop for biomass and a bio-fumigant for control of selected species of nematodes.
There are also some plant species that trap nematodes in their roots.

The hobby threshold for personal taxes is $5000 in Australia. If you don't include any of that as income you can't claim the expenses or sales tax.
Most people would do ok under that system, except maybe hobby jewellers with high value gold or silver craft materials as their inputs.
About 5 years ago the Australian Govt applied the GST sales tax to overseas purchases via E commerce.
That was under pressure from major retailers to stem E commerce from cutting their margins.
It is still mostly cheaper to purchase from overseas, especially on sale items. Also depends on the currency exchange rate and postal charges which are a rip off.
The GST makes a slight difference, but probably not enough to stop anybody, especially if you can't find something locally.

Syzygium malaccense is also native to Nth Qld. The fruit is not as great as the really good types, but the plants are probably a lot tougher. It might be possible to graft an improved fruiting type onto a tougher rootstock plant malaccense. Maybe even another closely related Syzygium.
I have grown quite a few Nth Qld Syzygium, they are mostly fairly tough outside that area. I often found growing from seed was better than trying to move seedlings south.
The choice of pot mix is also important in helping them survive winter.

How are the nematodes getting into the pot mix ?
Years ago  a family member potted Citrus into river sand and red loam ( the type of red soil you see in outback Australia. Result lots of nematodes on those trees ).
Since then I have used pine bark mixes or the same river sand and coir peat. Have not seen nematodes since in pots.
Solarising soil mixes might be a precursor control for nematodes.

I did grow a Vaniglia orange, but it went on the back burner as I wasn't too rapt with the fruit flavour, neither here nor there in a way for my tastes.
I haven't given the variety much attention, maybe it has it's moments ?
I probably prefer some of the Blood Oranges that fail to develop pigment due to the weather, still an Orange but lighter flavour than Navel etc.

Citrus Buy, Sell, & Trade / Re: Japanese citrus growers?
« on: November 24, 2022, 02:53:05 AM »
Are you importing fruit for consumption ? What is the time frame involved Japan to Canada ?
The ordinary post and priority from Japan to Australia is far faster than Australia to Japan.
There are plenty of websites in Japanese for individual Citrus farmers, but how to connect ??

Citrus canker on fruit is probably more of a problem than Tristeza via fruit.
Seed are not likely to transmit either, if hygiene controls used to extract seed from fruit from Canker areas.
Tristeza is mechanically ( graft ) or insect transmitted.

16
January in Japan is mid winter. Maybe not much local fruit in some areas. There are probably various fruits coming from the warmer areas of Japan
also stuff grown in tunnel houses or out of cold storage. I was able to find various Citrus out of season, and the Fuji apples are nowhere bigger or better.
I hear there are some pretty impressive strawberry varieties these days.

17
I'm assuming they were cross pollinated so I don't think I'll be growing the seeds.

You might get closer than you think. Some people in Australia grew seed of a new hybrid plum and it fruited pretty close to original.
They might be bred by being  X pollinated but also maybe not AA X BB gives AB F1 hybrids.

Tropical Fruit Discussion / Re: Fruit Trees with high ornamental value
« on: November 23, 2022, 05:05:21 PM »
Clove tree.
Star Apple, with the gold leaf undersides.
Quince for its beautiful trunk and branches, matched by some tropical Ficus and Alectyron.
Even more so Strangler Fig with its complex mesh of entwining roots. Like H.R. Tiger artwork  from the Alien films.
Syzygiums for foliage and new growth flush tips.

I posted this on the Citrus section re some Phillipines Citrus.
Citrus hystrix/Makrut vs Biasong vs Samuyao 
https://tropicalfruitforum.com/index.php?topic=39947.0

Biasong and Samuyao  are closely related to Citrus hystrix/Makrut Kaffir Lime.
I would be interested to know if you could even find them readily in the Phillipines ?
They might be rarer now or regional specialities ?
Really interested to know how different the fruit are to the well known C. hystrix.

That is interesting. I once tried a very large purple pear shaped Syzygium malaccense that was like a fantastic juicy pear.
The Keisui pears in your post are Nashi pears.
How do they compare with other Nashi pears ?
We sometimes get Nashi imported from China, Ya Pears. They are very light and crisp textured. Juicy but crunchy.
Interested how these Keisui compare to other Nashi.
Are you going to grow out the Keisui seed ?

Citrus Buy, Sell, & Trade / Re: Wanted: Desert lime (Citrus glauca) seeds
« on: November 22, 2022, 02:32:12 PM »
So basically, don't order from boutique-vegetale.com because they're claiming that it's "not obvious" and "too early" to tell that the plants are C. australasica and not C. glauca.
I contacted them and they're "looking into it" or something like that.

Those seedlings you grew are clearly not C. glauca. I would say also that they clearly are of C.australasica parentage.
Just wondering if those leaves seem a little long and the thorns a little long too to not be a hybrid ?
Hard to tell, I do have some Fingerlimes with longer leaves that look like that, but I haven't grown those seedlings recently.


22
There are probably two possibilities.
Grafting a seedling scion onto a mature tree might induce flowering in the scion by plant hormone activity,
ie the activity of a flowering hormone coming from the mature tree, or the reduction of an inhibitor in the grafted scion.

You could also induce flowering and maturity by physical growth.
If a seedling grows 1 metre per year, grafting a scion from it, onto a mature rootstock tree might cause it to grow and much faster, say 2 or 3 metres per year.
The placement of the scion and cutting back the mature tree to force scion growth ( top working) can result in rapid growth.

https://fruitandnuteducation.ucanr.edu/fruitnutproduction/Persimmon/Persimmon_Scion_Rooststock_Selection/

Kaki persimmons can be grafted to Kaki, American and D. lotus.
Some info on above link.
It is recommended not to graft non astringent Kaki varieties to rootstock seedlings of astringent Kaki varieties. Mainly fruit quality reasons.
Not sure how this relates to D.kaki on D. virginiana ( American ).
Are American Persimmon fruit astringent ?  The fruit is not seen much in Australia.

Tropical Fruit Discussion / Re: Giant citron or citron-lemon hybrid?
« on: November 20, 2022, 02:51:32 PM »
I have an interesting lemon that is very small, but the fruit will ripen (turn yellow) and hang on the tree ripe for 1 year before it starts to dry up inside.

That sounds very interesting. Any more info on that ? Any Pics ?
There are a few dwarf patio Citrus in Australia, a small fruited Key Lime and cutting grown Myer Lemon and a Lemon.
Yours might be nice fruit size for dwarf trees in balcony patio pots.

( Any macrophylla rootstocks on the way for grafting it to ?   ps That is an In Joke from Citrus General Discussion on the Forum ).

Citrus General Discussion / Re: Calamansi x Tangelo Hybrid
« on: November 20, 2022, 03:37:55 AM »
Odd enough both inbreeding and crossbreeding....can have similar effects. So could be a hybrid or could be a weird seedling.

You can certainly get unusual seedlings from both inbreeding ( selfing ) and crossbreeding.
The changes in selfing could be from shuffling the genes around or throwing some out.
The changes from crossbreeding are more from swapping genes between pollinator and receiver. ( some of the above may occur too ).
It is often possible to take a good guess as to which of the above happened, from the look of the seedling.
Hybrids often look like a combo of two parents.
Variable Selfs often look like a version of the parent, sometimes slightly odd, sometimes quite odd, but still with parental characteristics
