Taking advantage of this thread of conversation in which they are talking about the varieties of this beautiful fruit that is the nispero I would like to consult something related to this.
Is there any difference to prune one variety or another of nispero? I do gardening and a client has consulted me, and the truth escapes my knowledge. I have been looking for information on the subject but I have only found articles that speak in a general way about pruning (a clear example is that of this post that explains quite generally how to trim any loquat tree)
I hope your help, I have already thrown this query in several forums and I have not obtained great results. I hope this is the right forum. 
Thanks for the link.
Loquats in our region are quite vigorous and responsive to pruning. They can be pruned in most ways, and will adapt well in most cases. I have seen ones trained into a beautiful fence in Coronado.
In Argentina, I would judge their ability to cope with pruning by tracking vigor of known trees in the area. If they show substantial vigor, and lack of disease (fireblight is the big one here), then most pruning techniques should be effective.
They produce pannicles on new growth similar to mangoes, so that would be a good reference if you're looking to promote production and ease of harvest. If you're doing it for landscaping, they do respond well to shaping (whitewashing exposed branches may be necessary).
You always see the massive loquats in Japan but I wonder how the flavor is and if they thin the entire panicle to one fruit to maximize size.
I've been to the farms, they do thin to one per pannicle. The fruit are very large and the flavor is on par with the better varieties I have tried stateside. Jim Nietzel had one called 'Chinadoll' that had received glowing reviews. I have found a seedling with rich syrupy taste. There's lots of variety in the local seedlings.
