There are some comments on storing Green wood in the help sticky at the top of the section.
You can use anything on the ends of the logs or any end grain surfaces, Hot Wax, PVA adhesive, old leftover paint (it's a good way to use up those part used tins).
some use packing strength Cling film, the aim is to mimic the moisture loss speed to that of the Bark Covered surfaces.
Fruit wood is notoriously difficult to dry in log form without it splitting, I have better luck in cutting it into slabs 75-100mm thick ( don't seal the side grain faces just the end grain ends.
The slower you can dry it the better your chances, fruit wood is usually rather close grained and dense and it takes a long time for the internal moisture to migrate to the surface, if the surface wood dries out quicker than it's migrating it will split.
