Fruit sown occasionally in Japanese bed (5)
I believe the answer is:
futon
'japanese bed' is the definition.
(I've seen this in another clue)
'fruit sown occasionally' is the wordplay.
'occasionally' indicates alternate letters (letters taken at regular intervals or occasions).
'fruit'+'sown'='fruitsown'
The alternate letters of 'fruitsown' are 'FUTON'.
'in' is the link.
(Other definitions for futon that I've seen before include "Jap. quilt bed" , "Japanese mattress with wooden frame used as bed" , "Japanese mattress with frame, a bed-couch" , "Sleep on it" , "A Japanese bed-mattress" .)
