Tropical Fruit Discussion / Re: Fruit ID - possible Australian native
« on: February 06, 2023, 01:37:15 PM »
To me the CSIRO classification of it as S malaccanse seams strange. It looks to be different enough to be classified it's own species.

Many plants when classified by the key system will fall into a species. In this case it must key out as malaccense.
Maybe DNA analysis might show unseen differences to either confirm or seperate ?
Syzygium aqueum also occurs in Cape York, but the fruit are not as big as the cultivated types from SE Asia.

I don't see how the Oak would keep the psyllid from laying it's eggs on the citrus?

It was discussed on the Citrus General Discussion.
Something from the oak helps the greening affected Citrus recover and reduces symptoms.
Oak leaf tea is used as a treatment in the trials.
Similar to the Finger Lime peptide, it imparts resistance / recovery.

Transgenetic is the answer?

If you could identify the greening resistant genes and pop them into a Navel Orange etc without changing other fruit characters that could work.
Otherwise you could hybridise with resistant Citrus, but most likely the fruit would be slightly unusual.
If you did enough hybrids, maybe 2nd generation, you should get something that would pass as an orange or for juice purposes.
Otherwise change to new Citrus types, greening resistant types like Finger Lime.
That could work, replacing your morning " OJ " with a glass of "FL", except that Florida is also FL, co CA Citrus Farmers might get upset with that ?
Also here in Australia it would be "AuFL", except that our football league is the AFL, and it also sounds a bit like awful.

For Sports Fans here are some great AFL moments of 2022

Kumquats and fingerlimes do best from what I know.

If I remember correctly, they are closely related in the Citrus family.

"Echium gentianoides is rare, being confined to La Palma in the Canary Islands, and classified by the International Union for Conservation of Nature as vulnerable due to browsing and predation by goats and other invasive species.

There may be trees or researchers at the sites listed above.
I think there are still Breadfruit trees at the old Kamerunga site.

These rare fruit groups might be useful to contact

Oaks are not native here in Australia, and not that common except in parks in cities. I am more inland and not sure I have seen any here.
Any advice as to what species are used for greening protection ?
Think the experiment was with Live Oak, anybody growing Citrus with other species ?
Spanish Cork Oak may grow here, or maybe American Oak species "Out of the South and Texas Too" ?

The Oak treatment sounds interesting, possibly the research can't be commercialised as anyone can grow under oaks or make oak leaf tea.
Maybe that put it on the back burner, unless a specific Oak chemical was isolated and marketed as a treatment.
Still that wouldn't stop the simpler treatment version being used.
A peptide from greening resistant Fingerlimes is also being investigated as a treatment.
Some research into Fingerlime Citrus hybrids, or other Citrus hybrids that have higher resistance is also going on.

Definitly not Malay Apple, as the fruits are large, atleast 40 to 60 mm.

I think it is thought of as a wild relative of the cultivated types.

fruit nerd, was that a wild tree or in a park or garden ?

Citrus General Discussion / 'Bưởi' is the Vietnamese word for Pummelo
« on: February 02, 2023, 04:37:28 AM »
Some years ago I was in a local Vietnamese grocery and noticed they had a Pummelo in the small Buddhist Shrine in the shop.
I was in a rush, and also didn't want to be disrespectful about the offering in the shrine, so didn't ask about the Pummelo.
About a week later, I was back in the shop, and asked the Lady owner if they sold Pummelos ?
There was a language barrier, as the word Pummelo is not Vietnamese, and also I thought the word for it was Nam, because one of the Vietnamese types is Nam Roi.
Anyway, it went back and forth for a while, me making fruit sizes with my hand for Lime, Orange, Grapefruit, which made sense to both of us, but crashed at Nam.
The Lady was helpful, and suggested I come back after school when her son was working and he could translate.
I tried the hand gestures and Citrus types again.
Finally it clicked for her, and she said '' Ah, you mean Buoi "
Then it clicked for me too, and I remembered that was the Vietnamese word for Pummelo.
We were both happy with the breakthrough, and the Lady said the Pummelo fruit should be back in on Tuesday or Wednesday.
I still wanted to be sure about when to come back in,
so I asked " When will you get the Buoi in the shop" ?
The Lady quickly replied,
"He comes back after three thirty, after school"

I am still working on my pronunciation of Buoi.
Only last week I was walking in my neighbourhood, and noticed an elderly lady in her garden with six 2 metre pummelo trees along her fence.
We chatted, and I asked about the Buoi trees, to which she quickly corrected my pronunciation to one she was happier with.
She said the trees were Pink types grown from seed.
I had seen them often while driving, but never noticed any fruit yet.

Tropical Fruit Discussion / Re: Not enough Durian Discussion
« on: February 02, 2023, 04:04:38 AM »
I popped into my local Asian grocery here in Victoria, Australia and grabbed some Durian Candy. close smell and faint taste.
A few weeks back tried a Frozen Durian Soy Smoothie from the Bubble Tea Shop. Not a bad effort, nearly convinced.
That is how far I have fallen from my time in Cairns, ate a lot of Sunday and Monday unsold ripening Durians from a friend who sold them on the Friday and Saturday fruit market.

info on the Australian type malaccense

You can also search other Australian Syzygiums on this site. A few have purple fruit, but malaccense could be right.

It could be an interesting one as a rootstock for the better fruiting types from SE Asia. It should be a little tougher, for people wanting to growth further south.
That is one that I never found wild in FNQ, only the cultivated types.

Any other info, one seed or multiple seeds, solid flesh or hollow fruit ?

What is the foliage it is resting on ? Is that the plant it came off ?

Tropical Fruit Discussion / Re: Best time to graft loquat?
« on: January 30, 2023, 04:43:21 AM »
Does Loquat grafting season vary with rootstock ? It is compatible with a few different species as rootstock.

As I understanf it, there are no buds below the cotyledons. I believe that it is possible for a bud to regenerate from callus tissue, however, this takes time and there won't be enough energy in the seedling to support it that long unless it is in tissue culture media.

Apart from the agar gel, the tissue culture medium has nutrients. Anyone think you could supply the nutrients to seed raising mix.
Most seed mixes have fertiliser, but the TC nutrients are more tailored ?
Since the seedling is green it can photosynthesise, increasing the lighting duration and intensity may help it push through.
The Citrus general discussion had a topic on feeding albino seedlings with nutrients ( sugars ) to keep them going for a while longer than normal.
Any thoughts on plant hormones to stimulate bud formation.

Tropical Fruit Discussion / Re: Planning a trip to OKINAWA in June -
« on: January 28, 2023, 04:44:04 PM » is some info about what fruit and season available
Possibly Travel Blogs might give you more specific info about where to buy.
You could also try Japanese websites and translate.
A lot of individual small farms have their own pages.

Yes I have heard of it but never eaten it. I have been to Tokyo, but did not find it in shops. It is famous from Nagasaki area ?

Citrus General Discussion / Re: Honey Pomelo seedlings
« on: January 27, 2023, 07:56:59 AM »
Pummelos are not nucellar clonal, but they don't throw highly variable seedling types either. The seedlings are most often Pummelo.
A seedless type on the other hand may have been cross pollinated, so seedlings could have shorter maturity than straight Pummelo.
You can probably compare the parent to the seedlings for some idea of their origins.

It works so well that here on a sunny cold day itís -30f outside and over 80f (26c) inside.

How do you go with condensation drip or ice formation on the inside roof ? It is a problem here with frost in unheated plastic tunnels at below zero.

The Beachcombers, it was on TV here back in the mid 70's when I was a kid. I think they repeated it a lot in school holidays. Must have seen the first few series many times.

Shade houses, and irrigation, hand watering to soak them up. Overhead sprays to stop them drying out quickly.
42'c is not uncommon but we haven't had a run of them for a while. If the nights stay hot that is what dries them out the most if you don't watch out for that.
Then to relax go home and watch some movies about really cold places about - 30'c,  or reruns of The Beachcombers TV series, salvaging those logs with their speedboats.

Itís -30c here again todayÖIím crying a bit on the inside.

it will be 40'c here tomorrow, it was about that xmas day too. Hottest ever was 47'c. If you like sci fi, its like virtual reality sensory surround.

I have found the fruit in Nth Qld. The fruit are large, tennis ball plus. The pulp tastes like weak seedy black sapote, or a bit like wood apple pulp. Interesting, edible not the greatest, but has beautiful scented flowers. It grows right on the beach, mass blooms with that gardenia scent, romantic nights on a tropical beach, oh the memories.

i keep goldfish and some native species

Plantinyum, what native Bulgarian fish species do you keep ? Just wondering what they might be ?

 We have Carp, Tench, Redfin Perch ( Perca ) and Rudd/Roach introduced to Australia.

Cold Hardy Citrus / Re: Zygotic Poncirus hybrids
« on: January 26, 2023, 01:42:29 AM »
For commercial Citrus rootstock seed production I don't think there is any attempt to exclude pollination from other nearby rootstock Citrus types.
That is in mixed plantings or rootstock seed trees, including FD and PT.
Off types may need to be removed, but the seedlings are usually highly uniform for rootstock use.
I have found variants in rootstock seed, but never thought they were pollinated hybrids.
