Some things can be propagated from fruit stems (the citrus can be one of the most obvious examples, i have propagated some citrus from store bought fruits stems), but citrus stems have buds into the stems almost till the fruit. Durians, on the other hand seems to have (at least from a quick examination i gave to the only one fresh fruit i got), a dedicated fruit petiole which should abscind at the fruit's maturity (sot like an apple). Since on petiole you don't find buds, you can root or propagate that (unless you can regenerate the meristem from differentiated tissue, which is pretty hard, unless you can get your hand on expensive equipments and protocols).
