info on roots please

[vyltan]

If I remember correctly, epiphytic root is made of 2 main components, the velamen witch is the spongy grey/white matter, and the root itself witch is the hard cord-like structure in the middle.

My question is the following: if u have a healthy root except for half an inch section in the middle of its length witch is rotted and the velamen removed on that section,
are the nutrients picked up by the velamen away from that section still transported and used by the orchid?
