Maybe ma sees it's a sort of seed (6)
I believe the answer is:
sesame
'a sort of seed' is the definition.
'maybe ma sees' is the wordplay.
'maybe' indicates anagramming the letters.
'ma'+'sees'='masees'
'masees' is an anagram of 'SESAME'.
'it's' acts as a link.
(Other definitions for sesame that I've seen before include "Open .... is a pantomime cry" , "Plant cultivated for seeds providing oil" , "'Open . . . . . .'' is a magic phrase to gain access" , "Seed or oil used in cooking" , "Opening word for the oilplant?" .)
