Ok, in non auto forms mode JAWS will read the selected or first element when it encounters a tree in VPC. When one switchs into forms mode by pressing space, navigation is then handled by the JAVASCRIPT on the page. But you stated you were not working with JS so navigation would be impossible there too.
When you mark a element as treeview the screen reader sees it as one widget,. often developers will use a list of buttons or links with ariaexpanded and no role sence this works without JS and can be navigated in Virtual screen reader modes.

As you know, Aria treeviews are intended to implement a keyboard interaction pattern which is coded using Javascript. Screen readers Jaws and NVDA know this. So when you tab into the treeview (assuming the first element is focusable the screen reader automatically switches into forms mode (Jaws) or focus mode (NVDA term for the same thing).
