Tropical Fruit Discussion / Multi stem Avocado rootstock seedlings, Can I strike as cuttings or root ?

Multi stem Avocado rootstock seedlings, Can I strike as cuttings ?
So I have a bunch of rootstock seedlings, mainly Zutano and Reed.
Quite a few are multi stemmed.
Still on the seed, pencil thick or less diameter, 6 months old.
Any thoughts on striking some as detached cuttings ?
Otherwise thought of trying to root them.
Maybe top the pots with sand, or a filled tube over the multi stems to induce roots.
Some version of the clonal Avocado method ?
Anyone heard of or tried this ??

Citrus General Discussion / Architectural development of some citrus trees from seed planting to blooming.

Architectural development of some citrus trees from seed planting to first blooming.
Interesting study, goes beyond node count theory to describe the flowering structures of a seedling as it matures to flowering.
Some interesting thoughts on the role of grafting to replicate the structures.

Citrus General Discussion / Anyone growing fruiting Citrus amblycarpa ??

Anyone growing fruiting Citrus amblycarpa ??
I'm wondering if the fruit flavour has any resemblance to Citrus hystrix juice, as according to some descriptions ?
There seem to be a few versions of it available, some say tiny sour mandarin.
Guessing some aren't the real one ??

Citrus General Discussion / Flamingo Red Pummelo..Seedless ??
« on: November 26, 2021, 05:56:39 AM »
"Flamingo" – Red Pomelo is a hybrid of the 'Chandler' pomelo with a hybrid of a Shamouti orange and a clementine.  This pomelo variety ripens in the period from October to December and unlike other varieties it maintains its red color when the temperature drops. The pomelo is sweet (14% sugar) and seedless and its special feature is the presence of lycopene.

Anyone know if these are completely seedless or just "seedless" ??  Just found some fruit for sale.

« on: June 28, 2020, 08:03:24 PM »
Just wondering if anyone has ever seen fruit of either Biasong aka small flowered papeda and / or Samuyao aka small fruited papeda?
How do the fruit of either compare with Citrus hystrix/Makrut ? Are they fairly close or quite different? .
