It looks like a nice tree. Sorry I cant ID it any further.
Are Avocado fruit available in shops or markets in Ludhiana ?
Maybe it came from where the fruit farms are ?
Maybe it is one of those types ?
What type of Avocado fruit can you buy in India ?Are they Local or Imported ?

Those photos are interesting.
I am in the Southern Hemisphere ,right now my Alemow fruit is a bit bigger and light yellow colour.
A few early Citrus are also just starting to flower here now, end of September, early spring.
I am thinking your fruit is a lot greener than when I would pick mine.

You can tell different Avocado varieties apart by the leaf shape and colour of new growth, and tree shape if you know what you are looking for.
It is hard question because we don't know the source of the grafts.
It could be a more tropical area to the south, a neighbouring country,
or an agricultural research station in your area.
It could be grafted from a unique fruiting tree in your area ?

Mexican varieties have anise scented leaves, so if it has scented leaves it is more likely a Mexican type or Mexican hybrid.

Other members might be able to guess what Avocado race the tree could possibly be ?

Not sure about that, I guess you can get good seed out of green Makrut / hystrix fruit, another Papeda type.
As for macrophylla, I was not in a rush to eat them so I waited till they dropped / knocked off.
Unless you are rushing to sow the seed, maybe wait till yellow.
The fruit do seem to get full size and hang at the green yellow stage for a long time.
Maybe that is why it is popular in the Phillipines, holds well on the tree ?

Various cheap clear plastic medium duty thick bags are available, such as 200 litre bin liners, to larger mattress protector bags from bed shops ( cost $2 each here ).
These are pretty cheap may to make mini greenhouse covers, for one season.
A 100 watt incandescent bulb ( old style) can be used inside a mini glasshouse etc to warm the air for frost protection.

There is a limited number of Finger Limes available in USA.
Also because of greening restrictions possibly less types officially available in Florida ?
Possibly 'Australian Red' available in Florida is a particular release ?
I think UF has been working on them recently.

Citrus General Discussion / Re: TDS levels and gray water watering
« on: September 22, 2022, 05:28:55 PM »
My tap water is showing about 310 on the TDS meter.  Since I've started using soap nuts instead of laundry detergent,  the laundry gray water levels have been 300-350.

Yes that is not a big jump. Soil should act as a buffer, and soil organisms should consume some nutrients too from soaps and detergents.
That could depend on soil type, very light soils might offer less buffer and microbe activity,
As you are in a drought regime, you may not be able to apply any non grey water as usual, or rely heavily on grey for multiple irrigations ?
Check the ingredients of the Oxiclean, there may be a sodium component as a stabiliser ?

They can be after ripened with ethylene gas.
That is done in a chamber for commercial fruit.
Another trick is placing the fruit with a banana in a sealed plastic bag.
In Japan Kaki fruit were placed in empty Sake barrels to ripen them.
Might be worth checking out at what stage the crop is picked ?
I think they are at the orange yellow stage but still firm.
Not sure how earlier you could pick them.

TDS is derived from EC (electrical conductivity)
Tds/ec measurement does not tell you what is dissolved, just how much electrically charged particles are in solution. Without testing a sample there's really no way to be sure what is in it.

As I understand it you still have to watch the EC of water you apply, including liquid fertiliser mixes ( and ultimately dry fertiliser that dissolves in water ).
Basically if NaCl salt has an EC, then so does CaCl, MgCl, and also MgSO4 etc etc. all common component of fertilisers.
Yes some are going to be beneficial nutrients and some more harmful, but a very high EC from any compound can be a problem, particularly in pot plants.

Yes the latex will stick to your hands too, pretty hard to get off. Gloves might be the best.

Citrus General Discussion / Re: T-Bud grafting of citrus
« on: September 21, 2022, 06:58:53 AM »
Not having access to budwood, but having a number of young citrus in containers (and a few older in ground), I've been cutting buds from the middle of live branches where the small branch is at least round.  No success yet and I don't know if this is because my designated trees don't seem to have slipping bark, or the buds are small, or because it's a bad way to collect buds.  Do you have any thoughts about this?

It could be a good place to start, using your own material, as it eliminates some factors involved in failure, i.e. incompatibility and incorrect budwood storage.

Any ideas why the failures are happening in your case ?
Bud dies by infection via petiole scar.
Fungus infects under tape, whole bud goes fuzzy grey and dies.
Bud looks good until tape removed then it dries off and dies soon after ( not healed ).

Chip budding is another simple technique, doesn't need bark slipping.

You could try using different tapes.
Buddy Tape or Parafilm can have better results, as you don't need to remove the tape for the bud to shoot.
Weather and irrigation can also be important. I usually avoid overhead irrigation until buds have shot.
Hygiene can be important, clean hands and tools might also make a difference.
With correct technique, very tiny buds can be quite successful.

Citrus Buy, Sell, & Trade / Re: WTB 日向夏 Hyuganatsu
« on: September 21, 2022, 02:16:33 AM »
Seasons/Availability
Hyuganatsu citrus is only available for a few weeks in the early to late spring when cultivated in outside orchards. The citrus is also grown on a small scale in greenhouses, producing fruits from the mid-winter to the early spring.

Today Hyuganatsu citrus is primarily grown in the Miyazaki Prefecture and is found through specialty distributors, roadside stands, and local markets. The citrus is also grown in other regions of Japan under the names Konatsu and Tosakonatsu

Info from Specialty Producehttps://specialtyproduce.com/produce/Hyuganatsu_Citrus_15764.php

Not sure if you could track down a fruit if you visit Japan ? Might still be available from coolroom storage ?

13
Mexican Race Avocados, the more cold hardy type, have Anise scented leaves. Hybrid varieties can have some anise scent too.
You may be able to screen seedlings for Mexican ancestry ?
It may or may not be directly linked to cold tolerance, but it could be an interesting marker to watch out for ?

Have you asked locally?
I " phoned a friend " in Cairns, said one of the Durian Lovers ( lives in the Daintree ) has eaten it in Borneo.

"Itís a snacking durian, P ate them in Borneo just growing wild at entrance to national park"

15
the survival of the fittest "method" is suitable for getting the fittest individuals, IMO not suitable if people looking to breed dwarfs or for specific fruit characteristics to mention two parameters.

Yes, less vigorous types can be grafted onto rootstocks overcome that problem. Avocados have a few rootstock choices for different situations, Citrus has a wide range of choices.
As I remember there were a lot of Avocado seedling vars in FNQLD, some got to markets, a lot of types on the Tablelands on peoples fences, a few in the bush.

16
In my opinion there is no definitive answer because most Citrus are hybrids of several original species.
Some Microcitrus can fruit from seed in 18 months,
West Indian Lime 3 years,
Mandarin 6 years,
Pummelo 10 years plus.
Citrus cultivars are complex hybrids of the above and more.
There would be different systems and genes counteracting each other at times to induce or delay flowering maturity.
What works in one case may not work for another.
On top of that there is climate, in areas of continual growth i.e. tropics, flowering and growth to node count can be achieved much faster.
Node count is a good rule, but there are certainly case of Citrus plants flowering well before it is achieved.
Presumably mutations that lessen the effect of one or more controlling genes.

17
Any chance of collecting seeds from a Cafe or Restaurant that uses Avocados ??
They are widely used in Australia in those places. Not sure in your country.
Another possibility is Supermarkets that need to discard over ripe fruit .
You could also buy them in bulk and give them to friends, to get the seed back.
I do this here, but I am in a growing area so they only cost me $1 each off farm.


"Although south London is Zone8b-9, so it isnt even reaching its threshold in terms of cold hardiness"
Ok, but the tree is growing very well, not just sitting there having a hard time.
You are probably better off starting with seed of cold tolerant varieties, or at least keeping to commercial hybrids of Mexican Guatemalan, which are pretty common.

Cassowary, not sure I fully agree with the survival of the fittest for a breeding program in all cases, but I do know other people in FNQLD that grew Avocados from seed by throwing them hard out the kitchen window into the Jungle, and they got a lot to grow.

Cold Hardy Citrus / Re: Trifoliate orange
« on: September 19, 2022, 12:02:12 AM »
Benton Citrange is quite passable, slight mandarin flavour, better than Troyer or Carizzo Citrange.
Thomasville Citrangequat is not too bad.
Swingle fruit are ok here, Pineapple scent with a bit of Trifoliata.
As I remember from Citrus Growers Forum, a member had a fruiting Swingle in Germany but found the fruit not so great in that climate.

19
The London video is great, don't miss the follow up with a few more trees and a fruit.
https://www.youtube.com/watch?v=47evMZyBtXQ
It would be interesting to find out what variety they are ?
Suspect seedlings, but could be grafted ?
Looks a bit like a Bacon type.
Also seem be fairly old trees, so not seed from recent varieties.
I think there are some other places in the UK with very mild climates ( coastal ) that can grow tougher subtropicals.

20
The question came from a member in Hungary, not sure where their Avocados would come from, maybe Israel, Spain etc ?
As for other parts of Europe, could be coming from USA, Mexico, South America, Australia ? You are probably right about the types available,  ( or Hybrids of  ) but might be a few more diverse types also ?

21
Most Avocados in the supermarket are from large groves of the same variety. Probably with another variety as pollinator ?
Seedlings will be variable but maybe not that much ?
Zutano seeds and Reed seeds from farms are used as rootstocks, seedlings from each var are close enough, slight variations not too great.
Other rootstock variety seeds are similar, yes variable but not enough be unusable variants.
From 50 Zutano seedlings, I got about 5 odd ones, different leaf shape, closer nodes etc.
My point is probably that there will be cold variance in seedlings, but they could also be mainly fairly similar ?
Agree, probably better to start with a Mexican origin type if possible.
Also be careful of multi factor selection.
You are looking for cold tolerance, but vigour and root disease resistance will also play a part in the survival of your seedling trees.
If you want to favour cold tolerance, you may need to protect seedlings from being killed by another factor.
i.e. the most cold tolerant may not be the most vigorous, or most disease resistant.
Any chance of collecting seeds from a Cafe or Restaurant that uses Avocados ??

From the video, he could be starting the seeds in bigger pots to get more root development
Bacon var is known for cold tolerance in Australia.


22
Also you will want to stump the tree and graft onto new growth  if you have a tree that is already growing well and you hang a 2nd type on it, the new type will most likely never catch up to the original tree.  That is assuming you want them to be equal halves.

That is reworking / Topworking.
Any methods to produce double grafted trees from the seedling nursery stage ? i.e. as per Citrus or Stonefruit or Apple multi grafts ?
Clonal Avocado rootstocks sort of travel this path, until the lower stock is sacrificed.
Lots of people have one garden tree and need a pollinator.
Also wondering if I grafted high on a seedling rootstock, or already grafted nursery tree, would both sections throw fruiting branches after planting out ?
One of the members on the Citrus General Discussion top works Citrus high up, to keep part of the original variety fruiting, add a new variety and save tree space.

Tropical Fruit Discussion / Re: Tropical Sources of ALA (Omega-3)
« on: September 16, 2022, 06:45:43 AM »
Purslane, there is a larger leaved type in some inland areas of Australia.

Taken from the Royal Botanic Gardens website; The tiny black seeds are one of the most important bush foods of inland Australia, containing up to 20 per cent protein and 16 per cent fat. Joseph Maiden (1889) reported that Aboriginal people Ď€˜pulled up the plants, throwing them in heaps, which after a few days they turn over and an abundant supply of seed is found to have fallen out퀙. The seed is processed by grinding it on a flat rock with a hand-held stone. The resulting flour is made into a damper. Low (1989) comments that the oil from the seeds stains the grinding stones. The leaves and stems are also edible. They can be pounded into a mush and eaten raw, cooked as a vegetable or added to salads.

Generally purslane is known to have abundant omega-3 oils in the leaves. It also contains vitamins A, B and C as well as calcium, magnesium, iron and potassium.

This was kind of discussed here.
https://tropicalfruitforum.com/index.php?topic=48658.0
To add to that, It has often been quoted that the Red Finger Lime is Citrus australasia var sanguine from Mt Tamborine, ( cool area )
however Red Finger Limes are found throughout the natural range of Finger Limes.
However these are still highly variable plants, some are from hotter areas and some from cool highlands.
Some selections might be affected differently by climate, i.e. flowering or fruit set.
The development of red pigmentation of some varieties seems to be climate affected.
It is possible that a particular selection of Red Fingerlime would perform poorly in some areas, but it is not a blanket rule for Red types as far as I know.
I think TFF member Mike from Cairns had Red Fingerlimes fruiting there, in the tropics.
As there are less Finger Lime selections available in USA, maybe see what happens, or grow it bigger to produce more flowers.
Not sure how different rootstocks might influence performance in hot climates ?

You could find some NZ Citrus Nursery sites and see what they grow.
Also you might want to narrow down the areas in NZ for cool growing regions.
