Not if the key is easily identifiable by the parser as what perl likes to
call a "bare word" (as it is in this case). If you wanted to have spaces
or punctuation in your key or if you're composing a compound string like
"$dir/$file.$ext", you need the apostrophes (or, in the compound string
example, double quotes). And obviously, a single scalar could be put in
place of the bare word without any quoting, like: $qhash_ref->{$key}.
