Citrus General Discussion / Citrus in art exhibition
« on: Today at 02:38:05 PM »
This came up on my FB feed, I thought it was impressive.

A rare opportunity to see the work of this significant member of the Madrid Realists, Isabella Qunitanilla. Featuring 100 works spanning the artist’s entire career and including her most important paintings and drawings, I'll be travelling to see this one and look forward to sharing more images with you. 'Isabel Quintanilla's Intimate Realism'
Thyssen-Bornemisza National Museum, Madrid. 27 February to 2 June 2024. Pictured: 'Garden' 1966.

Citrus General Discussion / Re: Canola oil for pests experience?
« on: October 22, 2023, 03:23:08 PM »
I wen't down the non hazardous / non toxic route for plant pest control. Still noticed minor effects from many " natural " control agents, biological control agents. If you have safety equipment, I would be using it. If a spray tank line nozzle gets blocked or pops off, you can get drenched or hit in the face. It is probably pretty safe, but you don't need canola and pyrethrum in your eye or up your nose. Yes it probably takes longer to suit up than spray, but might be worth the hassle. On of my friends who worked long term in a fried food shop developed a lung disorder from the oil vapour, not uncommon it seems. You won't get that from occasionally spraying, but your being exposed to tiny atomised droplets, which is different to what the rats were tested on. I would go safety where possible.

The Bergamias I have seen are pretty close to an Earl Grey Tea Bag in scent.

The scent of Bergamia is pretty distinct. If yours match that scent, it is going to be very similar. If the scent is only somewhat the same ( weaker ), that is another clue.
If your seedlings are either  identical, or quite different that will tell your more.
You could have variable seedlings from self pollination, or from crossing to another Citrus.
Since Bergamia are mainly grown as ornamentals or for perfumery, not edible fruit, you could get something interesting.

On the topic of Terra Preta, what did you find out about the method it was originally made ? Bio Char is interesting, but not the same thing ??

Syzygium glenum from the Daintree FNQ, not edible but very rare.....on 17 trees ever found in the wild.rare.....

Variegated Fig (Ficus variegata). The figs change from green to red as they mature and feed many species of birds and bats.
The figs grow on or close to the tree trunk, a feature termed cauliflory.

Tropical Fruit Discussion / Re: Mango Thief Caught
« on: September 10, 2023, 09:13:01 AM »
There is a big leap from grabbing a few fruit to eat or grow seed, to ripping off trees full of fruit to sell.
Most often I will ask first, and rarely get knocked back. If a tree looks neglected or fruit falling unpicked, I may not ask first.
I must admit to collecting a fair few seed in this way, so find it hard to get too mad when people do the same to me.

Citrus maxima has a lot of cultivars, from SE Asia as far south as Indonesia and PNG to Japan an China. I saw them growing in Tokyo, which has humid summers and cold winters. You might want to choose cultivars from similar locations. That certainly works in reverse, as Tropical varieties can have fairly sour fruit in temperate areas, but other varieties taste fine there.

“He" that is without sin among you, let him cast the first stone fruit''

Dwarf Avocados usually have shorter internodes, ie spaces between the buds. This causes dwarfing as the foliage is more compact.
Some varieties are smaller growing trees, but not dwarfing as above.
There are a few of these varieties.
Rootstock may also be another factor.
Not sure it has been researched, but a dwarf on a less vigorous rootstock variety may be more compact than the same on a very vigorous rootstock.
Gem Linda and Wurtz are compact types.

Sorry I missed that from your earlier post.
I enjoyed racemosa cluster fig, faint strawberry flavour, like a strawberry cookie. I thought NSW sandpaper figs are nice. If I remember, Deciduous Fig was ok, Moreton Bay was ok, but a few are enough. Not sure any come near Ficus carica in flavour.

Have you tried investigating the accession number. Ficus 52406 might have other records, like introduction information.

I have tried quite a few Australian Rainforest Figs, this doesn't really ring a bell.
If it was that good, it might be better known.

"A large clean tree with fruit of fine delicate sweet flavor and size of a black Smyrna fig, only more rounded and dark crimson when ripe."

Interesting that this doesn't clearly ring bells.
Cluster Fig sounds pretty close by size and colour. Flavour is OK too.
Sandpaper Fig seem closer to domestic figs, but I have never seen red fruit, and they are smaller fruited than carica.
Going by the above description, you could eliminate a good 35 to 40 of the 45 Australian Ficus.
That leaves the most likely candidates for you to experiment with.

Tropical Fruit Discussion / Re: Foreign mango familiarity
« on: August 25, 2023, 07:56:23 PM »
Just tried a tray of Chaunsa here in Australia. Very nice, slight Durian note. Also coconut. I ate too many Mangoes free off the trees on my first days in Cairns, so most varieties are not top of my list, but these were really nice.

Citrus General Discussion / Re: Calamansi / Calamondin as rootstock
« on: August 21, 2023, 05:01:25 AM »
I believe it is used in the Phillipines as a rootstock, along with Calamandarin. Maybe try researching that. From what I recall, it was used as rootstock for Pummelo.
It should be OK for related things, like Fortunella and Mandarin, maybe Limes ?

Apart from crossing for hybrids, have you considered grafting ?? Hardy rootstocks could increase the productivity of existing Tomato cultivars.

Another possibility is graft chimeras, this has been done for Tomato X S.nigrum.  Budding is done so that a combination shoot grows out, creating a hybrid.

nullzero, what is the source of your Solanum opacum ?? It grows wild around here in Australia, probably unnoticed as most people would think it is introduced S.nigrum.

Greensand is a rock dust source of Potassium, basically very fine granite dust. You can get it from the places that make cemetery headstones by cutting granite.
Potassium citrate is another source I have seen. Potassium is common in rock minerals, so there should be other sources.

Citrus General Discussion / Re: Citrus seed vendors that can do phyto?
« on: August 12, 2023, 06:12:57 PM »
unlike Australia which has had an infusion of Chinese funding and germplasm to support closer ties with China around the citrus industry — all of which is export-restricted.

Can you expand on this ?? I knew they had new Chinese varieties, but didn't know about the funding or links. That is very interesting.

Have you investigated "double glazing". Twin skin / twin wall coverings are used to create a further insulating air layer between the wall sheets. Thee are also IR infra red films that trap heat. Also another factor is how the cover disperses light, to create a better light scatter


havent heard of those, are they used with glass windows, like between the 2 layers of glass?
Do the infrared films stop any light spectrum? In any way they are ment for glass aplication

Not necessarily glass, can be two layers of plastic greenhouse film ( separated ). Some people put bubble wrap on the inside of house windows for privacy and insulation. Some people fix a clear plastic film inside their wooden window to create a still insulating layer over the window.
Woven clear plastic films are an alternative to polycarbonate. they have a good life span, can be used as walls on many structures, or roofs on dome or tunnel structures.

Great article, pagnr! Have you visited the Botanical Ark?
No, but I did often visit " Next Door". on the same road, and did buy some fruit when Mrs Carle ran a fruit market stall at Pt Douglas.
The pic of the front gate of Carle's brought back memories. Shrouded in foggy rainy mystery.

Mine too, if we ever make it back to the area. Wish I had known about it when we were at Cape Trib 20-some years ago.

I was up there too around then, a few times 97 -- 99.
I was lucky that someone I knew was living up there, so was able to spend a bit of time.

Also remember they filmed Island of Dr Moreau, with Val Kilmer and Marlon Brando. Never saw those two but did see an Asian Forest cat, one of the animal cast.
Amazingly Marlon Brando wanted the script changed, so that Dr Moreau, who always wore wide brimmed hats and thick sunscreen,
wanted the final reveal to be that when he took his hat off, revealing a blowhole on the top of his head, and that he was in fact a Dolphin hybrid...Genius.

There is no reason why an Ai can't breed Paw Paws.
They can order supplies online, rent facilities, pay a technician to water or pot up plants,
fund a research project into unique pollinator insects, and acquire some of those insects, use algorithms to invest, and use those funds to purchase land.
They could hack into military satellites and zoom in and pinpoint individuals wild Paw Paw trees with modified facial recognition software.

It is when people in the future start picking and eating those Paw Paws, that the trouble is going to start.

You may or may not believe me, but I am from the future,
I came back to try and stop P Day.
