"The silver ... of the moon, / The golden ... of the sun" (Yeats) (6)
I believe the answer is:
apples
(Other definitions for apples that I've seen before include "Crisp fruits" , "Stairs (Cockney rhyming slang)" , "-- and pears" , "''The silver ... of the moon, / The golden ... of the sun'' (W B Yeats)" , "Eg, russets, pippins" .)
