Fruit and vegetable wholesaler's closing (4)
I believe the answer is:
pear
'fruit' is the definition.
(pear is a kind of fruit)
'vegetable wholesaler's closing' is the wordplay.
'vegetable' becomes 'pea' (pea is a kind of vegetable).
'closing' says to take the final letters (the letter which ends or closes the word).
The final letter of 'wholesaler' is 'r'.
'pea'+'r'='PEAR'
'and' acts as a link.
(Other definitions for pear that I've seen before include "Cone-shaped fruit" , "Shapely fruit?" , "William, maybe" , "Conference, perhaps" , "Alternative to apple" .)
