Fruit gathered in fall (7)
I believe the answer is:
plummet
'fall' is the definition.
(to plummet is to dive or fall)
'fruit gathered' is the wordplay.
'fruit' becomes 'plum' (plum is a kind of fruit).
'gathered' becomes 'met' ('meet' can be a synonym of 'gather').
'plum'+'met'='PLUMMET'
'in' is the link.
(Other definitions for plummet that I've seen before include "Fall at high speed" , "Fall like a stone" , "Plunge headlong" , "Fall rapidly" , "Fall headlong" .)
